Virus of a new kind:

Hello,
i am Siva.
I am having a trouble with a kind of virus in my computer.
It entered my pc thru a pen drive. Also i don't have an internet connection with it.
The symptoms are:

The infected folder consists of a folder icon with the name of the same folder but with an .exe extension.

The System directory consists of folder icons with names FUN.EXE , DC.EXE and a few more.

When i attemp to delete these they are recreated.

In the Task Manager, Processes tab, i could find proceses named fun , dc , etc. which comes under user created processes.

After a month , i think it is active, because taskmanager is blocked from veiwing and frequently my applications are minimised automatically
