Dear Avast Team,

I am getting message from past 4 days that suspicious files found using heuristic method.It is not allowing me to delete the file.Its in Operating Memory
Its in
E:\WINDOWS\SYSTEM32\DRIVERS\13BBCE38.SYS
E:\WINDOWS\SYSTEM32\DRIVERS\MSSUMSSU.SYS

At Boot scan it deletes the virus,but after restart the virus again pops up.Also my Windows XP hangs for about 15 seconds while loading due to virus.Actually the virus came into the PC when my brother was downloading some software from LIMEWIRE.Please help

Google does not give any results on those filenames, so they are really suspicious at least.
