Windows users hopefully know that their systems are open to

online attacks

without some

reliable security software

installed. Be it Windows' overwhelming market share or security oversights in the code (or both), Microsoft's flagship product gets the lion's share of the bad guys' efforts.

If you're running a legit copy of Windows XP, Vista or 7, Microsoft Security Essentials is free and protects your computer from all kinds of Internet nasties.

Malware, spyware, viruses, Trojans

et. al. be gone!
