My system started malfunctioning again 3 or 4 days ago and what I discovered was my folder packed up with Desktop_.ini. Even after reinstalling a fresh copy of windows after uninstalling the old one even formatting my windows drive didn’t solve the issue. I am still trying to solve the issue and can’t do. Here seems to be a good discussion about Desktop_.ini issue.

This file i.e Desktop_.ini copies itself to every folder accessed. I am McAfee 10 Enterprise Edition but this virus, I believe has even cleaned up some registry values and I can’t even start Active Shield and My Firewall is also disabled. Tough Virus Ah!
