I think System Works is huge and bloated, at one time Norton products were must haves but now I think they are invasive and troublesome. The Zone Alarm firewall is good as is the Zone free version also or the free Kerio/Sunbelt offering. The free version of A-Squared is a usefull addition. click here
click here If you are a Barclays customer you can get a 30% discount, just click on security as you log in. I have had problems in the past with both of the programs you have and I ran ZA & AVG free for a long time, but I can recomend F Secure. Try the 30 day free trial.
If you are happy to pay for these products then I would recommend "AVG Plus Firewall". It is low on resources, effective and a good price for two years updates. You can also try a 30 day trial before buying. click here
Is there anything better than Zonealarm on protecting you from the internet? As ive decided i dont need all the protection Zonealarm gives, so i dont need protection on every program and msn and all that. As i believe it slows my computer down too much, but i still want a good service on the internet side of things?
