Ok, done!

Avast uninstalled.

Ok, procede with other steps…

And re-run FRST and post me the fresh report…

Virus total link: https://www.virustotal.com/pt/file/d2e15811a4322b95e1ab5a7b36f092aba912ec294fc04efb9af660b1ef1d8f3b/analysis/1383828113/

And the frst attached

Ok, we’re nearly done, but there are still the remnants of Kingsoft antivirus? Can you uninstall it through Control Panel?

Well, Kingsoft is not listed on that installed programs’ list. I asked my father and he said he doesn’t recall installing Kingsoft.

Ok, we’ll remove it in next step

1. Open notepad and copy/paste the text present inside the code box below.
To do this highlight the contents of the box and right click on it. Paste this into the open notepad.

R2 kisknl; C:\Windows\system32\drivers\kisknl.sys [215928 2013-01-25] (Kingsoft Corporation)
C:\Windows\system32\drivers\kisknl.sys
S1 KDHacker; \??\c:\program files (x86)\kingsoft\kingsoft antivirus\security\kxescan\kdhacker64.sys [x]
S2 kxescore; "c:\program files (x86)\kingsoft\kingsoft antivirus\kxescore.exe" /service kxescore [x]
c:\program files (x86)\kingsoft


2. Save notepad as fixlist.txt to your Desktop.
NOTE: => It’s important that both files, FRST and fixlist.txt are in the same location or the fix will not work.

3. Run FRST/FRST64 and press the Fix button just once and wait.
If the tool needed a restart please make sure you let the system to restart normally and let the tool completes its run after restart.

The tool will make a log on the Desktop (Fixlog.txt). Please attach it to your reply.
Note: If the tool warned you about the outdated version please download and run the updated version.

Any remaining problems? Reinstall Avast, and tell me how are the things now?

Ok,

I ran FRST and installed avast again. Everything seems to be fine.

Once again, thank you very much, your help was greatly appreciated.
