Infected with BuenoSearch

[Haereldir]

Hi,

I've just recently been getting the error: progid atkexcom axdata every start-up for a week now. I've scanned with AVAST Boot Scan and it detected a corrupted registry. Sadly, I wasn't able to record this. However, I've spent hte last hour scanning with Malwarebytes and the same things keep popping up. They have been deleted and quarantined over and over again, but they keep coming back. Everytime they were quarantined, Chrome closes.

Here is the Report:

Hello and

You need to update MalwareBytes:

 

Then run a scan and clean. It should no longer appear.

Thank you!

I feel stupid for not updating beforehand.

There are no more threats detected.
