PC Security: your questions answered

The answers to your most burning security questions

At PC Advisor we're deluged with your PC security questions. So here's our guide to getting rid of spyware, shrug off spam, and staying safe on unsecured public networks.

Why am I sending myself spam?

You're almost certainly doing no such thing. I once received the same spam message from a friend and from myself, after sending out a notice to people who knew both of us, we discovered a third party had the infection.

Most spam is sent from infected PCs, but the malware tries to hide the identity of the infected computer. To that end, it spoofs (forges) the sender address.

A little more detail: the malware searches the infected PC's hard drive for email addresses and sends spam out to them. But it also uses some of these addresses for spoofing purposes. So if you get spam from yourself, that means someone with your email address has an infected computer.

What can you do about it? Not much. But if only a few people have your email address, you might try letting them know about the problem. One of them has an infected PC. And if someone complains that you're sending them spam, send them a link to this article.
