cd \programdata
ren  "AVG Secure Search"  "AVG Secure Search.save" 
ren  AVG2012  AVG2012.save
cd  "\program files (x86)"
ren AVG  AVG.save
ren  "AVG Secure Search"  "AVG Secure Search.save"

All commands are succesfull? If so reboot and post results. Don't uninstall AVG yet!

sure you did all of this? (I editted post later). please look again

Don't reset bios. But do the following. Be sure to boot from DVD, so not from F8!!

BTW: what rootkit did you have? And how did you remove it?

TDSS rootkit?
If so:
C:\WINDOWS\system32\TDSSciou.dll - Win32/Agent.ODG trojan
C:\WINDOWS\system32\TDSSliqp.dll - Win32/Agent.OIK trojan
C:\WINDOWS\system32\TDSSnrse.dll - Win32/Agent.OIK trojan
C:\WINDOWS\system32\TDSSoeqh.dll - Win32/Agent.ODG trojan
C:\WINDOWS\system32\drivers\TDSSmhct.sys - Win32/Agent.ODG trojan

Code:

c:
cd \windows\system32
attrib  -h  -s  tdss*.*
del  tdss*.*
cd  drivers
attrib -h -s  tdss*.*
del  tdss*.*

All gone? Now just to be sure you have correct MBR bootcode:

Code:

bootrec/fixboot
bootrec/fixmbr

Code:

reg  query  HKLM\win7sys\Microsoft\Windows\CurrentVersion\Run
reg  query  HKLM\win7sys\Microsoft\Windows\CurrentVersion\Runonce

Any strange startup items?

Code:

reg  unload  hklm\win7sys

Or download Data Recovery | AVG Rescue CD | AVG Ireland . Download the ISO, burn it and boot from it. Scan for virusses. Anything found? Cleaned?

This is critical information to identify. Unless you can exactly identify it, you will often find that the best solution to get a 100% guarantee the system is clean, is to perform a clean install after running a DISKPART and CLEAN or CLEANALL.

I know its not ideal, but its the safest solution.
