I believe that The Renegade is pretty much on target with his classical definitions here. Most AV products are not very good at detecting trojans because they are not necessarily harmful, and they require user intervention to load.

As suggested you should use several products when it comes to dealing with spyware and adware.

With Spybot Search & Destroy, remember to use the "immunisation" facility that will block quite a few

With your AV, AdAwareSE and SpyBot, you should update them then reboot into SAFE MODE and run them from there. They will have a better chance of detection and removal that way as a lot of malware won't load in safe mode so will be dormant.

You might like to try Ewido as another product, it has a very comprehensive detection for around 100,000 nasties. OK it is only a 14 day trial with the interactive scan running, but it is free and updatable after that for manual scanning.

You should get into the habit of emptying your browser cache, history and temporary files after an online session and before you re-boot. Don't forget to empty the Java cache...........in fact I usually disable the Java cache.

I see that TDS3 from DiamondCS has been mentioned. Whilst at that site get their free "RegistryProt"..............you might as well stop the damn things from landing in the first place

Also get Win Patrol (it is free)

Ok, from the EC member state of Austria allow me to introduce:

A-squared is a very good (and free) anti-trojan tool

Please allow me to repeat, apart from Moosoft's "The Cleaner", you should run all this stuff in

safe mode

Good luck, and happy hunting
