Hi everybody, i'm new here and need help please.
A while ago my PC got infected with the Brontok virus. (email/USB virus)
I've removed the Brontok worm by means of Avast Bootscan from C:\System Volume Information.
Now my PC behaves strange like;
1)Sometimes my PC reboot by itself,
2)TeaTimer.exe not showing up in the taskbar,
3)Avast only shows up the second time when opened.

I've read somewhere that after removing Brontok, a PC is never the same again. (is this true?)

Now i need some info like what this strange names in the S&D directory means;

HEHIFR.scr
KHQVRJAXJJEKKVXV.scr
NVYLKWYBBZLWWENXH.scr

Could this be Brontok files created to oppose S&D's functions?

I use S&D version 1,5,2,0

Your help regarding this will be very much appreciated.

Regards
