Hello,

 

I searched the forums, found similar topics but could not find the solution for my problem.

 

Malwarebytes anti-malware detected several times. I deleted these every time. But coming again and again.

 

Pelase find the log file for the last detection attached.

 

How can I understand if this is false positive or not?

 

Your help would be much appreciated.

 

Best regards

Andach

I have followed your instructions.

 

There was a problem. After restart Windows started with temporary profile.

I managed to take it to normal profile by changing entries in Regedit.

 

Please find the fixlog file attached.

 

Please kindly advise what the problem was and what we have done to correct it.

 

Thanks and best regards.

My greatest concern was this brower.exe process and the restrictions set by the infection. Something was modifying your Hosts file as reported by MBAM.
Key Found : HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\browser.exe

I aslo remove anything else that was not required.

How is the computer running now?
