Hello,
I did a lot of looking around and the I decided to do ask the question

My computer has two operating systems,one XP and one mandriva.

Now my XP has avast antivirus,which was working fine.
Recently I started reciveing error messages n my avast antivirus that my PC has been infected with a worm called autorun.inf.
I tried deleting it ,removing it moving it...nothing would just work.
The same message kept coming over and over again.
I did a boot scan from avast ..but nothing really helped.After the second boot,the same message began appearing again and again.

Now i booted in to Mandriva and read my ntfs partion ,There I found three .com files lying in he c:\ of my computer
namely
h.com,i.com,ofddh.exe,ntdlr,autorun.inf

I again rebooted into windows and did a whole scan ,nothing was caught.
I am quite sure that h.com and i.com are not windows files.
my antivirus is upto date
I tried googling them but that too would not help much.
Any help from you guys will be highly appreciated
