MyDoom.F impact

Typical - the first recent virus that does damage to the users local files as opposed to just launching a DOS attack or act as a zombie (which the firewall would have prevented) and this is the one that the user gets infected with, AND with no backup of their data!
The cost to us was a days downtime whilst I had the users pc shipped to the office to work on, 5 hours of my time to hack the box to change the administrator password (as this was set by a previous company and I wasn't bringing the machine online to change the password over the network!),run the av software check (which took about 3 hours to run), run adaware to remove the spyware (gator) on the machine and check for windows updates (remarkably uptodate!) I also had to run a complete network sweep which REALLY slowed everyone's machine for about an hour - and all because updates were less than a day old and someone was daft enough to open a weirdly named attachment. In their defence the file did look a .txt file due to large amounts of spaces and changing the icon to look like a .txt file instead of a .exe file
