Lock your Flash Drive by BitLocker . . .



Password Protect your Pen Drive using BitLocker



Sometimes you may need to protect your USB Flash Drive/ Pen Drive or Drives of your PC. And for this purpose you may use or think of using third party security tools. But do you know that Windows OS offers a better way to secure your drives? Yes! BitLocker Drive Encryption could be a great tool for you . . . 


Applies to - Windows 7 or above


You can use this security feature both for your internal hard disk drives and also for external flash drives or hard disk drives. Here I will mainly focus on USB Flash Drive. Before we start I believe you have a - 
  • A Personal Computer with OS Windows 7 or above
  • A USB Flash Drive 
  • Minimum skills to work with Windows OS

And remember, I'm working on Windows 10. So few terms may not match with yours if you're on Windows 7 or 8. Don't get nervous in that case. Simply try to find the similar terms.  


How to use BitLocker?

  1. Insert your Flash Drive on USB Port.
  2. Now go to This PC/ My Computer to see your drives.
  3. Right Click over your Flash Drive and Choose Turn on BitLocker.
  4. Now you will see a window asking for password. Choose use a password to unlock the drive.
  5. Now enter your password 2 times. Remember, password should contain Uppercase and lowercase letters and numbers. > Press Next.
  6. Save recovery file to your desktop and Press Next.
  7. Choose Encrypt used disk space only > Compatible Mode > Start Encrypting.
  8. Wait sometimes and you will see Encryption is complete!

Now remove your Flash Drive and insert it again. Check your drives and you will get your Flash Drive locked.

If you try to open it then it will ask your password. 


Unlock BitLocker Protected Drive by Password


Keep your recovery key in a handy place. If you forget your password then recovery key will help you unlock it. 



How to Turn off BitLocker?

Well it's quite simple. If you need to turn off this feature then unlock your drive first. Then follow the steps below - 
  1. Right click on your flash drive.
  2. Choose Manager BitLocker.
  3. Click on Turn off BitLocker.
  4. Now you will get a window decrypting your drive.
  5. Wait few moments and this feature will be turned off for your drive.

Caution!

  • If you forget the password and lose your recovery key, then the only way to access your drive is to format it. And it that case you've to lose all of your data contained inside. So be sure about the safety of your data. 
  • Don't eject your device while encrypting or decrypting. It may cause damage to your data or device. 


Fact!

Encryption and decryption speed depend on the amount of data you stored in your device. 



Disclaimer!

By no means Marks PC Solution will be responsible if your drive gets damaged or if you lose important data. 


Thanks for your time. See you in the next post . . .

Test your Site on Safe Browsing Site Status



Google Safe Browsing Report


Couple of days ago, I noticed a sudden fall in my site's traffic. It was not clear why Marks PC is experiencing a decreasing traffic. Later I discovered a harmful content in my site. That's why Google Chrome was stopping visitors to enter my site. Then I fixed the issue with the  help of Google Safe Browsing and Webmaster Tools. In this post, I'm gonna share my experience with you . . .


Warning Message from Google Chrome



About Safe Browsing Site Status

Safe browsing site status is a part of Google Transparency Report. Everyday it collects and examines billions of URLs to find out harmful contents on those websites. If a site is safe to surf then it's okay. 

But if harmful contents are found, Google enlists the sites in blacklist. And Chrome browser shows warnings to the visitors. 



Check your Site

You can check any site on Safe Browsing Site Status. It maybe your own site or any other site you visit often. So, what are you waiting for? Let's check a site on Google Safe Browsing Site Status . . .


Follow the URL below - 




Then you will get following view - 


Google Safe Browsing Report


Here you can see a search box named Status of. In this box, you will enter the link of your desired website. As soon as you hit the search button, you will see the current status. If the site is okay, you will see - Not Dangerous

If any malicious contents are found, you will see the status like dangerous or harmful



Taking Actions

If you're a site owner and find your site dangerous, don't delay a second. Immediately go to the Google Webmaster and sign in there. There you will get a message for critical issues. 

Sometimes you may know what is the problem exactly. Then fix it and inform the Google Webmaster that necessary actions have been made. Then you will request a review for your site.

If you're not sure about the problem, then talk to the experts. Or sometimes this problem might be caused by harmful ads shown on your site. In that case, you need to talk to the Advertisers. 

And never avoid this issue. If you avoid it, then your traffic will fall dramatically. And you will lose revenues. 


After taking corrective actions, Google will review your site. Within few hours (not more than 48 hours) Google will update your security status.

How to Disable or Enable Autoplay?


Disable Windows Autoplay


By default, when you insert any removable media (ie. Flash Drive, CD etc.) on your PC, windows will automatically open the drive. Or it may play media or start program contained by that drive. If you're good to go with this Autoplay Policy, then it's okay. But if your PC is vulnerable to virus, then you must turn off Autoplay. 


There are different methods for different versions of Windows which you can use to turn off Autoplay. But I'm gonna show you a universal method which applies to all running versions of Windows. 



Enable/ Disable Autoplay - Universal Method

Applies to:
  • Windows 2000/ XP
  • Windows Vista/ 7
  • Windows 8/ 8.1

I would like to use Group Policy Editor to perform this task. Simply follow the steps below:
  1. Press Start + R to open Run.
  2. Type gpedit.msc > Press Enter.
  3. Now you will get the Group Policy Editor window.
  4. Hit on Administrative Template under Computer Configuration > Windows Components > AutoPlay Policies > Double Click on Turn of Autoplay.
  5. There are three options - Not Configured/ Enabled/ Disabled. To turn off Autoplay, choose - Enabled > Apply > OK. 
  6. If you choose Not Configured or Disabled, Autoplay will be Enabled

How to turn off autoplay by gpedit.msc


Note: Autoplay Policy is available both on Computer and User Configuration. You should always use Computer Configuration. Because if there is any conflict between the two, Computer Configuration settings will be preferred. 




Turn off Autoplay - Shortcut Method

Another handy way to turn off Autoplay is choosing - Take No Action. When you insert any media on your PC, Windows may ask you what to do? 

In that time, you can simply choose Take No Action to turn off Autoplay. 

Turn Off Autoplay


Note: If you choose any action, next time this notification will not appear. 


Turn off/ on Autoplay from Control Panel

You can also turn autoplay on/ off from control panel. Follow the steps below:

  1. Go to Control Panel.
  2. Then open AutoPlay from there. 
  3. Removable Drives > Choose Take No Action to disable autoplay or Choose Ask me Everytime. 
  4. To enable autoplay, choose Open folders to view files. That's it. 

Disable Autoplay from Control Panel

Report Suspicious Sites to Google Spam Report


Google Spam Report


At the beginning, web technology was operated by the people who were committed to keep it safe. They were dedicated to build such a communication network that will turn the world into a Global Village. But there is a negative site everywhere. Some people always try to abuse the technology. They use technology to harm other people and thus try to get some personal benefits. What do you call them - Hacker, Spammer or simply Criminal? 


Google is trying to prevent the webspam. And you have a great opportunity to contribute to build a safer web along with Google Spam Report! Recently Google Webmaster Tool has introduced a new page through which you can report 10 types of suspicious site under following categories:
  • Paid Links - Page that sells or buys links
  • Objectionable Contents  - Page that contains inappropriate contents
  • Malware - Page that is infected
  • Other Google Products - Page that abuses AdSense, Google Maps etc. 
  • Something else is wrong - Page that is not webspam but has some other issues
  • Report Webspam - Page which is really webspam
  • Copyright and other legal issues - Page that violates copyright 
  • Personal/ Private - Page that discloses private information
  • Phishing - Page that asks for sensitive information like username, password etc.
  • Rich Snippets - Page that violates Google's Rich Snippet guidelines

Google defines webspam as - the pages that try to trick Google into ranking them highly. And before you file a webspam report, you should decide which of the above categories best describes the page. 

If the page has multiple identifiable issues, I think you should report the site which will punish it more! 



Here I would like to illustrate some practical situations - 


Copying Contents

If someone is copying contents from your site, you can report it to the Copyright and other legal issues category. And you must be the copyright owner. Or you can also report the site in Other Google Products category if that site uses Google AdSense Ads.



Link Sharing Site

Some sites share too much links. If you found a site which is primarily selling or buying links without providing services to the people, you can report that site under paid links. Users find it difficult to use the site due to the numerous links. 



Sites Sharing Malware/Virus

Some sites have downloadable contents. And often they share virus or malware. If you found a site that shares virus or malware, you can report this site in Malware category. 



Redirecting Sites

These sites are really boring for the users. Wherever you click on these sites, a pop up window may appear. Or you maybe redirected to another unwanted page. These sites could be reported in different categories. But I prefer Something else is wrong category. 



Site Revealing Private Information

Privacy has been a great concern now. Often we see, some sites reveals secret information about different individuals which is against privacy. If you found a site which discloses your personal information or someone else, you can report it in Personal/Private category. 



Sites asking passwords, username etc.

Some sites may ask your Facebook username or password to sign up or log in. Or they may want your Google username or password. Or they may ask for any information which they are not supposed to do. 

Sometimes you may find a fake site which exactly looks like a popular site. Suppose Facebok instead of Facebook. Or Goggle instead of Google. They are known as phishing sites. If you ever sign in to these sites by mistake, change your password immediately. Because you may loose your account anytime. 

If you found a phishing site, please report it in the Phishing category. It's popular method to hack someone's account. 



Really Webspam

If you found a site which contains wrong information, exchanging links, copying contents from others, too much posts within a few days, misguiding the readers, redirecting the visitors to unwanted sites - in a word Massacre - you can report this site in Really webspam category. You may find all sorts peculiarities there! 




Misleading Sites

Some sites mislead the usres. Suppose you search something in Google and found a site appropriate for your query. But after visiting the site, you've understood that this sites doesn't contain your desired contents. But it provides wrong information in Google search result. You can report this site in Rich Snippets category. 

These sites use such a description in the search result, that influences users to click. But when the visitors enter the page, they don't find necessary information. 

If you think, the contents of a site is not appropriate, then you can report it in Objectionable contents category. Or if you fails to decide the proper category, then use Something else is wrong option. 



The last thing I would like to tell you, I personally hate Phishing, Spamming, Copying and Malware sites. What do you hate most?

How to Sign out of Gmail Remotely?


How to Sign out of Gmail account from a remote location

Your email account is as important as your cell phone. Even sometimes it's more important than a cell phone. Because it may contain lots of personal as well as official information. Once hacked, it could be really tough to get back. So, you should keep your email ID safe and secured. Today I'm gonna discuss about how to sign out of Gmail from a remote location. 



Background Story


When I was in college, during my graduation, I used to sign in to my Gmail account from Computer Lab. And I used to select the Remember me option for quick login. One day, when I was working in my Gmail inbox, the electric supply interrupted. And I didn't have enough time to wait. So, I had to leave my account signed in to that browser. 


I was not sure whether the next user would get my account signed in or not. I was lucky that I didn't save my password. Otherwise anyone could see the saved password and access my account. 


However, there was nothing to worry about! Because Gmail has a great way to sign out of all other sessions except the current one. And you can also change your password any time. 






You may need to sign in to your Gmail account from different locations. Suppose your friend's PC, cybercafe, library, cell phones or any other public places. By mistake, if you forget to sign out, your account might be unsafe. Or if you lost your cell phone with Gmail account signed in, then what? Simply sign out of all other sessions from your Gmail inbox. 


Account Activity

If you need to sign out of all other sessions, then you have to go to the Account Activity options from your inbox. Account activity is available at the bottom of your inbox. If you're using basic HTML view then you will get the account activity as below:


Last Account Activity in Gmail

Look at the red mark. Last account activity. And look at the yellow shade - Detials. Hit on the details button to view your activities. And if you're using the standard view of Gmail then it looks like as below -

Last Account Activity in Gmail

And this will be located at the bttom right corner of your inbox. After hitting the Details option, you will be redirected to a new page named Activity on this Account. Look at the image below:


Gmail Account Activity


Since my account is not open anywhere, it shows - This account doesn't seem to be open in any other location. If there is any unusual login detected, it would show different message. 

Now look at the button - Sign out of all other sessions. If you hit on this button, your account will be automatically signed out from any devices/ sessions except the current one. If you're signed in into your mobile, it will also be signed out. 

Also look at the Recent activity table. It shows from where your account has been accessed, with location, IP address, date/time and duration.  


Hopefull this will be really helpful for you to keep your Gmail account safe. Facebook has also  similar option. You will get it from settings.

How to Check the Performance of Antivirus?


Test your Antivirus Performance by Sample Virus


It's been a long time since I discussed about PC security last time. Because I've talked about MSE and Windows Defender. If you use any of the two in your PC, I believe you don't need any other security tools to protect your PC. But if you use any third party security tools or if you've any doubt about your current security software, you can check its performance by a sample virus


Windows users often purchase security software ie. Norton, Kaspersky, Bit Defender etc. Many of them use trial versions to protect the system. But how much safe you are? Are these tools really working for you? Can these tools detect viruses or worms? Let's check it! 
  1. Go to Run by Pressing Start + R
  2. Type Notepad and hit Enter
  3. Copy and Paste the following code on notepad
  4. Now Save the file as Virus.exe 
  5. Scan the file with your antivirus

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

If your security tool is strong and if it has real time protection system, then you don't need to scan at all. It should be able to detect the file as virus automatically. If it doesn't detect the file immediately, then scan it. After scanning the file, if you see that your antivirus does nothing, remove the antivirus immediately. Because you're not safe with non performing security program. Rather it slows down your operating system. 


I've also checked this code by Windows Defender. Defender is able to detect this file immediately. Even if you save the file with .txt extension, defender can detect it. The background scanning system of defender is so strong. 

I believe Microsoft Security Essentials will do the same job as Defender. Both have tight security system. If your antivirus doesn't work well, you should use either MSE or Defender. Defender comes with Windows 8 by default. But if you're using previous versions of Windows, you can use MSE at free of cost.



Defender reports this file as: 


  • Item Name: Virus:DOS/EICAR_Test_File
  • Category: Virus
  • Alert Level: Severe
  • Description: This program is dangerous and replicates by infecting other files
  • Recommended Action: Remove this software immediatley

Protect your Documents, Workbooks & Presentations by Password !!


Protect your Documents, Workbooks and Presetations by Password


If  you're a regular visitor of Marks PC Solution you should notice, we've published lots of tutorials on Microsoft Windows, Microsoft Office and other software. We've also published many tutorials and tips regarding security issues. You can find those tips by using the search box. Or you can search by categories: Tips n Tricks, Tutorials, Microsoft, Windows, Security etc.  Today, I would like to share another tips on security.


Many of you might be familiar with the password protection system of Microsoft Office. If you're working with highly confidential documents, workbooks and presentations (ie. Exam Questions, Online Account Information, Personal Information, Other Secret files),  then this is a good idea to encrypt those files by password.


But if you are not acquainted with the password protection system you should go through the whole post. You should know, the different versions of MS Office keeps the password option differently. You will not find it similar in Office 2003, 2007 and 2010. That could be difficult for you to find the password option. That's why I'm gonna discuss about all versions. :)

Note: The procedure is very similar in MS Word, Excel and PowerPoint.



Setting Password in MS Office Documents


Office XP and 2003:

These two versions are almost similar. All the options and tools are located at the same place. Maybe they are different just by color! Let's start -

Open MS Office Document (Word/ Excel/ PowerPoint) > Go to Tools Menu > Select Options > Hit on the Security Tab > Type your Password on Password to Open Box > Hit OK > Save the Document.

Now whenever you will open the document, first you have to enter the password. Then you will be able to access the file.

I apologize for not sharing any image. I don't use 2003 anymore. I have been using Office 2010 for last two years. But this is very easy. You will have no problem to set password in Office 2003. Upgrade to Office 2010 or 2013 to enjoy exiting features!


Office 2007:

You know Office 2007 brings a dramatic change in the interface. Its ribbon interface is absolutely different from Office 2003 or XP. But Office 2010 and 2007 are almost similar except small changes in few options. Okay start -

Open any of the Office Programs (Word, Excel or PowerPoint) > Now hit on the Office button from the top left corner > Choose Prepare and then Select Encrypt Document > A small Password box will appear > Type the Password > Hit OK > and then Confirm it > Save the Document.

Look at the image below:



Office 2010:

Though Office 2007 and 2010 are very similar, but there are some significant changes in some of the options. A major change is the disappearance of the Office button. Instead of Office button, you will see the File button in 2010. See how to do -

Open either Word, Excel or PowerPoint file > Click on the File button from the upper-left corner > Choose Info > Hit on the Protect Document from Permission section > Choose Encrypt with Password > Type your desired Password in the box and hit OK > Type again to confirm it > OK > Save the Document.

You can take help of the image below:




Note: If you don't save the document after setting the password, then it will be removed automatically. Password will be enabled after saving the document. And remember, this password has no recovery options as you can do in Gmail, Yahoo or Facebook! So be careful!



Removing/ Changing the Password

Sometimes you may set a password for testing purpose only. For example you set password in a document that doesn't need password at all. And every time you're required to type it when accessing that file. Or maybe you want to change it. But when you try to remove or change that password you can't find any option to remove it. How disgusting!  :)

Well this is easier than you think! If you wanna change the password then repeat the whole process again until the password box appears. Then type a different password and save the document.

And if you would like to remove the password then just leave that box blank and save the document. Password will be removed. 




Hopefully this post will be helpful for you . . . :)
