Rundll32.exe 100% CPU usage

Evening all,

My brother's having some issues at the moment, whereby 100% cpu usage (or there, there abouts) is being used by Rundll32.exe I dunno what's causing this :crosseyed:

Any ideas?

if he was folding at home it'd show winFAH.exe or one of the F@H cores but he doesn't either ways..

He's not got any anti virus atm, S'pose i'll chuck some on there later

Yeah on a system connected to the net w/out anti-virus I would check that 1st as I recall a virus/trojan that ran as rundll32 but was in a different location then the real system file. ;)

Oh and a good FREE online scanner is housecall.

if u cant access any online virus scanner, then check the hosts file because the viruses add the antivirus sites to the hosts file making it not assessible.

Might want to do a full spyware scan too, I know some that can cause the CPU usage % to spike at 100% for a while. It's not necessairly a virus.

For spyware removal I normally use either MS Antispyware Beta, or Ad-Aware SE.

My antivirus is the full version of AVG Antivirus 7, which is VERY good!
