What's the best combination of antivirus, antispyware & antiadware softwares?

I am specifically concerned about backdoor viruses, trojan horses etc. Softwares MUST have real time protection. Please do not recommend AVG, Avast. Norton Internet Security 2007 wasn't able to detect a severe backdoor trojan in my system. It was a sasser worm which is very hard to identify %26 remove.

Thanks!!

the sasser worm requires a removal tool which many vendors have available

mcafee, kaspersky are good choices

zonealarm also has one

I use the free ones - always have and they work fine.

That'll be AVG Antivirus

Adaware and Spybot for spyware

and zone alarm for firewall
If you've already decided that AVG and Avast are not acceptable, why do you ask what is the best combination? You said you had a sasser worm. That is NOT a virus and antivirus won't find it and eliminate it. You obviously don't have anti-spyware and anti-adware, and what I recommend isn't apparently going to be good enough for you. You will get as many answers as there are opinions in this forum, and that's a lot. And viruses don't come in the back door, they come in because you click on something that is infected, or you open an infected email.
