HI Guys,
Just came across this announcement from Bleeping Computer today (via Twitter)
"Unfortunately it has come to light that the program ComboFix had a file in it that is infected with the Sality virus. The minute we heard about this, we pulled the executable so that it is no longer available from BleepingComputer.com. Unfortunately we have no control over other sites that may have mirrored ComboFix without permission, so please do not attempt to download it elsewhere."
Read the rest of the article if you believe you may be affected by this issue.
If you have offline copies of Combofix.exe which are infected then I would suggest you delete them and carefully verify that the virus has not spread beyond your storage media.
Kind Regards
Simon Zerafa
