I thought I'd share some valuable info regarding win-doze security, but I don't really want to put it on this site, as it's long, so I'm sharing a link to my own website where I've stored it. I'm not the original author of this, so I obtained permission from him to share it freely with others. It was originally sent out on a mailing list, which is also mentioned in the post.
Here's the link:

Those of you that still use windoze should find this valuable. Properly done, a windoze computer will likely not require an antivirus scanner running on it. I scan my system every now and then with a copy of Linux, but you could use ClamWin AV (it's free) if you're intimidated by Linux.
I should tell you all up front that I haven't had any antivirus or anti-spam software or email scanners on my computers in over five years. My son uses Win7 and makes good use of some of this info, and he also hasn't had any problems. He keeps Avast Home Edition on his system just to be safe.
Our browser of choice is Firefox, and our email client of choice is Thunderbird. I also use Sylpheed on some of my setups for email. We use these because they're more secure, especially when properly set up. I use a few plug-ins, or add-ons, called NOSCRIPT, DO NOT TRACK PLUS, and PHZILLA for the Firefox browser. I NEVER store cookies, prefering they be deleted every time on shutdown. My settings are tighter (I'm a bit paranoid) than my son's, but he also never has problems with his system either.
Your mileage may vary from mine if you use this info, so take responsibility for your own stuff. I'm a bit more adventurous than most, and not afraid of risks. Re-installing everything on my computer is no big deal to me. I did this weekly for fun back in the Win3.11 days, and doing it with Linux is even easier for me. I understand if you don't feel that way, as we're all different.
