Keylogger - Longterm protection advice please.

I recently had a keylogger on my machine that went undetected by several different programs that I had downloaded from your awesome download page. I followed the steps as advised and did not skip anything. The programs I used were Malwarebytes Anti-Malware, SuperAntiVirus, Spybot S&D, AVG, HiJack This, ComboFix, Registry Mechanic (Subscriber), NAV (Subscriber) and friend reccommended ZoneAlarm. None of these detected the keylogger. The reason I knew I had a keylogger is because 2 MMORPG's that I play have been compromised as well as 2 different email accounts, and quite possibly other things that have yet to surface.

After hours of searching for the keylogger I gave up and did a reformat and re-installed Vista. I had always considered my security habits would keep me safe from outside intrusion and regularly run anti-virus and spyware checks and was pretty surprised when I realized I had a problem.

I now know that what I was doing before is not enough and seek advice for a program that can protect me from these malicious threats. I realize there is nothing that is 100% guaranteed short of not connecting to the internet, but to say the very least I am pretty dissappointed with Norton Anti-Virus and ready to take the next step to replace it.

Any help is greatly appreciated! I have been visiting your site for several years now and you have always had an answer to any problems I had and appreciate the thoroughness of your responses to people's questions when they turned to you as a last resort.

I go to school full time and 90% of my classwork is done online. I also am an avid gamer and play a multitude of MMORPG's and first person shooters. I am willing to subscribe to the right program that fits in with my computer usage environment. I appreciate any help you can give. Thanks!

 

Thank you very much for your reply and I have gone down through the list and applied updates that your site has suggested. I am worried that I may not be doing enough to keep my machine secure however. I had several (7-8) anti-malware programs prior to a reformat and re-install and now I currently only have 3, shouldn't I need more or possibly one that claims to do it all?

I currently subscribe to Norton with Norton 2008, Norton Internet Security and Norton System works, but as long as I have been a subscriber with them they have never detected a problem on my machine, but many of the freeware versions have detected and removed the infections that Norton missed. With Norton I kind of feel like a victim as each time I decide to no longer use it, I have such problems removing it that it seems like it is easier to just re-subscribe and leave it on the machine.

I apologize for my ignorance on this matter, I only desire to have my machine protected as best as possible, and I thank you kindly for the replies.
