PUP.Optional.Extension.NFCS

Hello ,

Recently I've been having numerous problems with my computer: start menu and the search bar stopped responding, various applications I installed from the Windows Store do not open nor respond (Netflix, Facebook Messenger, etc.), neither does the Store itself, and some programs (such as Dropbox, Yandex.Disk, etc.) just disappeared from my PC.

Having run the threat scan with Malwarebytes (I attach the results below), I found out that my computer is infected. 

Please, help.

Hello @clerc_venne and

Yes, the logs show the computer has some issues. I don't believe it is infected, but probably needs some good clean up and repair.

Your use of BitTorrent is a very good way to get infected, and though it has some very limited legal use, the vast majority of BitTorrent traffic downloads are illegal. I would highly suggest you stop using the program.

You also have a very old compromised version of Java on the computer. You should remove all old versions of Java and if you really need it then make sure you have the latest version of Java at all times.

 I don't think this will find anything, but let me have you run it just to make sure.

 

Please download the following scanner from Kaspersky and save it to your computer: TDSSkiller

Then watch the following video on how to use the tool and make sure to temporarily disable your security applications before running TDSSkiller.

PC Winvids - How to run Kaspersky TDSSKiller

If any infection is found please make sure to choose SKIP and post back the log in case of a False Positive detection.

Once the tool has completed scanning make sure to re-enable your other security applications.

Thank you

Ron

Hello again, Ron @AdvancedSetup.

Thank you very much for helping.

I've done everything you suggested to do, no infection has been found.

And even though I can now open the Netflix app, I am still having a problem accessing the Start menu (it's not clickable but I can operate it through keyboard) and still my search bar isn't responding. Is there anything I can do about it? 

Thank you,

Clerc

Let's do another round of scans and if they come back clean we may need to look at doing some Windows Repair work.

 

Please run the following steps and post back the logs as an attachment when ready.

STEP 01

• If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• If you don't have Malwarebytes 3 installed yet please download it from here and install it.
• Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• Once the scan is completed click on the Export Summary button and save the file as a Text file to your desktop or other location you can find, and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know on your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Right-click on the program and select Run as Administrator to start the tool.
• Accept the Terms of use.
• Wait until the database is updated.
• Click Scan.
• When finished, please click Clean.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Copy its content into your next reply.

 

RESTART THE COMPUTER before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens, click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here.
• Please attach the Additions.txt log to your reply as well.

 

Thanks

Ron

Okay, just some minor stuff there. Let's go ahead and try the following.

 

Please visit each of the following sites and let's reset all of your browsers back to defaults to prevent unexpected issues.
If you are not using one of the browsers but it is installed then you may want to consider uninstalling it as older versions of some software can pose an increase in the potential for an infection to get in.

Internet Explorer

Microsoft Edge

Firefox
Click on Help / Troubleshooting Information then click on the Refresh Firefox button.

Chrome
Reset Chrome back to defaults to completely clear out issues with Chrome.

• First, go to >> Google Sync << and sign into your account. Make sure you know your password as this will clear it from the browser.
• Scroll down until you see the   "reset sync" button to clear your data from the server and remove your passphrase.
• Now, close all Chrome windows. Chrome cannot be running for the next step. If needed, print this information or use another browser to read the information.
• Press the Windows key + R at the same time, to bring up the run dialog box.
  • 
• Type in (or copy/paste) the following and press Enter:     %localappdata%\Google\Chrome\User Data\Default\

1. Press Ctrl + A to select all the files and folders.
2. Hold down Ctrl + A and click once on the files "Bookmarks" and "Bookmarks.bak". This will unselect them.
3. With all the files selected (except for your Bookmarks), press the Delete key and click Yes to delete the files and folders.
4. Example of all files and folders selected, except Bookmarks

 

Restart your computer now and make sure there are no longer any redirects or other browser issues.
