Hi,

 

I first noticed problems when my mic started muteing itself all the time.

 

So I have run malwarebytes witch detected rootkit.fileless.MTGen on my computer. 
Then I runned Zemana AntiMalware,

and after that Farbar Recovery Scan Tool.

 

I attached files from both Zemana and Farbar

Hi nasdaq,

 

I runned the fixlist (fixlog is attached) but my F-secure told after FRST had run that it had blocked it because it tried to change application (and then just location of the FRST) so I hope that didn't do anything harm to FRST.

 

I reseted my chrome

 

my mic seems to work (not muteing itself) now, but while looking for answer with the mic I noticed that lots of svchost.exe run and few of them (3) are running as user (as running under my username and not under SYSTEM or local etc).

Hi
 

I noticed that lots of svchost.exe run and few of them (3) are running as user (as running under my username and not under SYSTEM or local etc).

Srvhost is called by the operating system when required to execute a program.

If all is well you should have not problems.

Hi, 

 

If the Fixlog was fine and there is nothing more to do  and if those svchost.exes are fine, then I see no other problems with computer.

 

Thank you a lot and whole Bleeping computer
