Thread: Deleting Trojan from XP

I have Windows XP installed in my PC and all functioning well, but now problem is when I am checking my emails one message appears as system is infected by infected with Trojan.Agent/Gen-Clicker and it is able to delete it. But after restart same message appears again. So please help me to remove this Trojan.

Mainly Trojan.Agent/Gen-Clicker appears like legal purpose but actual work of it is to unsafe effect and simultaneously it downloads other dangerous software elements to user's PC without user knowledge. This application is probable to install other application without knowledge of user and it utilized by hacker too.

I am using Avast Anti-virus software for my Netbook. Plenty of Viruses automatically deleted help of it. So It is best for me.
