It sound to me that you have too many utilities doing the same job.
It is not a good idea to run more than one anti-virus or firewall program as they can stop one another working correctly. Also they are all actively running at the same time, which can be counter productive.
I use AVG from Grisoft which can be down loaded free at

The ZoneAlarm firewall is another free piece of software which is very good, it can be downloaded at

Since using both of these products I've not had a virus or PC invasion.
Adaware is a useful program to detect spyware, I prefer this to most others as it seem to detect more and I also use Spybot, between them my pc seems to run un-invadered.
Another useful utility is HiJackThis which when run tells you exactly what programs are loaded at boot-up. You then have the option to stop programs which you think can be malicious from being loaded.
This is probably better in the hands of the more experienced user.
