I came across an intersting event today. I haven't been able to research it as much as I'd like, but I'd like to toss it out to the community just the same.
 
A customers machine appears to be infected with some type of malware that apparently harvests email addresses and puts them into a file named '~'.  Just the tilde ~, no extention.  This file is created under the C:\Documents and Settings\%username%\~.  I have attached a zipped copy of the file for refrence.
 
I came across the file earlier today, renamed it and copied it off to a keychain USB drive for later analysis. Well, the file re-created itself and the malware creating it is not immediately apparent.  I've scanned all the running apps but I haven't had much time to investigate.
 
Any ideas?
