Be on the lookout for virus hoaxes. These are emails that are sent, often by well-intentioned friends or family members, telling you to delete files because they are viruses, when in fact they are files you need on your computer.

The body of the hoax virus email usually reads: "I just received an email that said I might have a virus that is spread from address book to address book. It is apparently undetectable by Norton and McAfee. It remains dormant for abut 14 days then activates and wipes out the hard drive data. When I checked my hard drive, I did find the virus and successfully deleted it."

The email goes on to give steps for removing a file named, sulfnbk.exe. This file is a Windows utility used for restoring long file names. DO NOT REMOVE IT!

Viruses and virus hoaxes can catch you off guard. Be sure your computer has anti-virus software, and be vigilant.
