Windows: Free Malware app from Microsoft

Microsoft offers a FREE antivirus/anti-other-bad-stuff application called
"Miscrosoft Security Essentials".

It is NOT the best thing out there, but works pretty well. It DOES "suck
up some CPU cycles" - i.e. when it's running your machine will slow down a
bit.

It is DEFINITELY better than running nothing - so if your subscription to
Norton or Symantec or whatever is running out, and you don't have the cash,
check it out.
