I have a virus that keeps adding extensions - can't get removed

Hi there,

I have a virus/some kind of malware that keeps adding extensions to my web browsers. I can't get it removed! I have tried a lot of antivirus softwares, that are able to find the program, to remove it from my PC. But when I start up my computer, the deleted files are back again. These files keep adding extensions to my webbrowsers to monitor my internet behaviour! How do I permanently get rid of this virus?! Can someone please help me? I've included some pictures of the virus/malware files on my computer and the extension itself. 

Thanks in advance,

Omar

Hello Ootje98 and welcome to Malwarebytes,

Lets grab some logs and see whats going on, continue with the following:

If you do not have Malwarebytes installed do the following:

Download Malwarebytes version 4 from the following link:

Double click on the installer and follow the prompts.

When the install completes or Malwarebytes is already installed do the following:

Open Malwarebytes, select > small cog wheel top right hand corner, that will open "settings" from there select "Security" tab.

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Close out the settings window, this will take you back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Click on the Detection History tab > from main interface.
  • Then click on "History" that will open to a historical list
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply

Hiya Ooje98,

Continue:

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.

NOTE. It's important that both files, FRST or FRSTEnglish, and fixlist.txt are in the same location or the fix will not work.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1: This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed.

My system is still infected unfortunately. This virus already tried to login into my email, social media etc. It's terrible. Still getting constant notifications from Malwarebytes. I think my last option is to totally reset my PC. What do you think?

It doesn't make any difference unfortunately, I've tried to reinstall both browsers as well. It seems that this malware file in my PC keeps adding those extensions to my webbrowsers.

Run FRST one more time, ensure all boxes are checkmarked under "Whitelist" but only Addition.txt under "Optional scan" Select scan, when done post the new logs. "FRST.txt" and "Addition.txt"

Open FRST and press the Fix button just once and wait.
