That post was, what, two weeks ago, and I'm struggling to remember what was in it. Didn't think I was old enough for senility to set in yet.
It might have gone a little something like this:
1. For spyware, download
Ad-aware and
Spybot Search & Destroy. These two programs are free, and do a reasonably good job of cleaning out spyware. A non-free option that I'm familiar with is
Spy Sweeper. Bear in mind that no one program is ever going to find or prevent 100% of all spam, but using a combination of them is usually pretty effective.
2.
You must use an anti-virus program. In this day and age, you're crazy not to. I am currently using Norton Antivirus 2007. Some would suggest using the full Norton Internet Security suite, but I think that's overkill for the average home user. For the last several months, Fry's Electronics (for those of you that have them nearby) has often been marking 3-user-license copies of NA 2K7 down to $45, and then offering a $45 mail-in rebate. I currently own 6 licenses of NA 2K7, and it cost me about $6 in sales tax. If you despise Norton, or don't want to spend anything at all, I recommend
AVG Anti-virus, which is surprisingly effective for a free download.
3. You should also get yourself behind a firewall, which protects you from numerous forms of outside intrusion. I personally prefer to use a hardware firewall (i.e. a router) which is usually quite effective and completely unobtrusive. A router is a device that connects directly to your internet connection (i.e. cable, DSL) and then shares that connection with multiple computers, all the while providing that protection from the outside. If you don't have a router, the Windows Firewall that is a part of Windows XP and Vista can also be effective.
That's as much as I can remember at this hour of the morning. Feel free to ask more questions, and the tech savvy may feel free to chime in with their own ideas as well.
