If you're the type who doesn't keep a virus-scanning program running on your desktop out of memory concerns, or you find yourself at a system without your preferred scanner, you might want to think twice before downloading any suspicious attachments—even if the boss sent them. Luckily, previously mentioned service VirusTotal offers the same multi-AV-scanning service through a utility email address. Simply forward your email, attachment included, to
[email protected], with the body cleared out and "SCAN" in the subject. After running McAfee, AVG, F-Secure, and other apps over it, VirusTotal will email you back to let you know whether the attachment is infected. High thanks to Digital Inspiration, which offers a link to similarly useful email addresses at the link below.
