#5. For a trojan scanner, which you should also get, try Moosoft's The Cleaner. This works VERY well.
5) The Cleaner is good but it costs money, only good for a 30-day trial without it. I prefer SwatIt. It was recommended to me for use in the office, and it's served it's purpose well. There's a version you can pay for, but there's also a free version that isn't a trial version. It's available from

#4. For a virus scanner, I would go with Norton AV '04. But seeing as you are nearly broke, you could try Avast, which isn't all that bad.

#2. A router simply takes one internet connection, and shares it with other computers located nearby, thus creating a network. Using a router is not a way of making your system, 'more secure' though it certainly can be. I.E. It is not a security tool or anything like that. Google 'linksys' or 'dlink'.
2) If you think that is all a router does, you have a lot to learn about routers. Routers support ACLs (Access Control Lists) and firewalling (Check out the 800-series cisco routers for a good home example). If you want to stick to home routers (there's a huge difference between something made by dlink or linksys and something made by cisco or nortel), then you still can't say they don't provide security. If I have a router in front of my system and I'm using NAT with no port forwarding and no DMZ setup, you are going to have a hell of a time getting access to my system. A port scan isn't going to reveal anything of interest to you, if you attempt to telnet in the router is going to drop the connection because it doesn't know which computer you are destined for. To take a very old example because I'm tired... I could put a Windows 95 machine vulnerable to WinNuke or a Windows 98 Machine vulnerable to IGMP Nukes on the net and if they are behind the router, your attacks won't be successful. A router is definately not the holy grail of security, but it does provide it's benefits.
