[danmurph]

Hi guys,

As soon as i turn on my computer; then at regular intervals I get a warning coming up from AVG saying \windows\system32\expsr.dll - trojan horse psw.generic5.vxd

Before I came here I tried various registry cleaners and anti-virus programs

All I know is that the virus is on my boot sector

I have followed the steps you have given me on here but

couldn't get kaspersky to work,
