[priya08]

System affected by Trojan horse virus. Anti-virus is having in the system but it is detecting the virus but not removing the virus...
Tell some antivirus to remove it....
when the system is logged on, the notification will that there is a virus each time i am deleting the virus but its coming again and again ...

and so the system is slow...

I like Avast myself, but the best way to overcome a virus is to reinstall - I even like switching hard drives, but that's because I have encountered hardware virii.

You said you have anti-virus and it even detects the threat. That's enough. Now, for quick solution just browse through the 'threat history' or 'log files' or whatever your anti-virus calls its reports. Note the name of the threat and search google for 'removing <virus name>'. It should come up with some unit tool to remove that threat.
