I don't think AVG's messages include one that says "Your computer may crash if you try to remove it". Perhaps the full error message would be helpful.
Which Trojan/Virus is being reported by AVG?
A trojan virus had just infected my computer few days back. When I try to remove it using my antivirus "AVG" it says your computer may crash if I tried to. My system(windows vista) slowed down after this infection.
So how do i remove it?
