You talked about Alcra F. That use to be a common limewire virus. Download a few copies myself but didn't run them. ;-).
Except on a test machine not connected to the internet and in virtual mode. Its interesting how these viruses destroy/disable regedit, taskmanager etc. That's why if someone's comp is not working I first test to see if regedit etc. works. valualble clue to whether they have a virus or not.
