PUP Firefox virus

[raul8]

Hi,

I do not have Firefox installed on my system.

But on startup a random Firefox window appears for few seconds and then system behaves weirdly.

I installed malwarebytes and it reported PUP.Optional.FirefoxNSR.Generic issue.

I quarantined it & I want to know, can I delete this registry from system?

I've Windows 10 installed.

 

Regards

Hello raul8 and welcome to Malwarebytes,

Run the following: Download Farbar Recovery Scan Tool and save it to your desktop. Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version. If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way... Be aware FRST must be run from an account with Administrator status...   Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.) Make sure Addition.txt is checkmarked under "Optional scans"   Press Scan button to run the tool.... It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply. The tool will also make a log named (Addition.txt) Please attach that log to your reply. Thanks, Kevin...
