By pure stupidity and lack of attention, I downloaded some sort of Malware on my PC.

It affected my browser and tried to send some data online somewhere.

I cleaned as much as I could with all sorts of steps, most importantly using AdwCleaner 6.047, NOD ESET32 10 and then going through registry and folders to erase as much as possible.

There are still two threats reported by AdwCleaner, both related to uefochubsrv.

I can't get rid of it, although my computer seems to be running normally.

 

Thank you in advance for any help.

Attached the reports from FRST

Hi nasdaq, thank you for a quick response.

 

I followed your instruction. Fixlog attached.

It appears that the damn thing can't be erased.

I ran AdwCleaner again and right after FRST action, 2 more threats were found.

I cleaned them but the main two remain (1 service, 1 file).

 

The computer seems to be running just fine ever since I purged most of the crap few days ago.

I can't be sure, though, whether there isn't something happening without me knowing...

 

It seems like the only way now would be to format the drive and reinstall the W.

I used the advice in this thread: https://www.bleepingcomputer.com/forums/t/647557/ucbrowser-uefochubsrv/

and it worked. No longer an issue.

 

Thanks
