I have an AMD sempron 2400+ with asus mother board on winxp home platform protected by avast antivirus.
Yesterday avast detected win32:dialer-520 [trj] infected my system. I tried to remove it by invoking a command delete from the message screen. It was not able to remove it since it was in the system background. I then forced a boot time scan. During the boot time scan it was able to catch and delete it. After the system got booted,again the trojan started appearing again and again. Since I am not able to delete it, I choose 'no action' to temporarily suspend that appearing. After a few minutes, it appears again.
Can some expert help me in getting rid of the trojan. Since Avast is able to detect, I am sure it will heal it. Expecting an advice.
thanks
