What is a really good program can detect and remove Trojans?

My PC has been running a little slow and freezing at times with hardly anything loaded on it, I think I may have a Trojan(s) I have avast home edition and it usually catches some infections and I also have spyware doctor (full version). I run auslogics boost speed to clean up junk files and other stuff to help with the slowness but it is not really helping. I have windows Vista so certain programs may not work on it.

Vista does use a lot of your RAM but most programs are completely compatible. It's good that your using Avast!. Now you just need to get some more anti-spyware.

No single anti-spyware application is perfect so I recommend using Ad-aware and Spybot (they are free). Other free anti-spyware programs would be AVG Anti-spyware (formally Ewido), Super Anti-spyware and SpywareBlaster.

I strongly recommend using FireFox, it's a far better and safer alternative to Internet Explorer. If you add-on McAfee SiteAdvisor, it will warn you of potentially harmful sites. I also recommend CCleaner which is a free system optimization and privacy tool.

Running these programs in Safe Mode (tap F8 after powering on the computer and choose to boot to Safe Mode) can be more effective.
