Make sure you're protected from MyWife aka CME-24 aka BlackWorm. If you're infected (you may already be), it'll corrupt files with these extensions:
*.doc
*.xls
*.mdb
*.mde
*.ppt
*.pps
*.zip
*.rar
*.pdf
*.psd
*.dmp
on the 3rd of each month; so Friday is the first day it will show itself. It's spread through email & disguises itself as winzip. So make sure anything you open doesn't have a double extension.
shows up as
file.zip if you don't view the full name...
