comodo is a good firewall, and comodo verification engine is very good to see you are on a genuine site very reassuring when signing in to banks etc.

Mc Affee site advisor is also good to see you are on to the safer sites from your search you will need it twice if you use both Internet explorer and Mozilla fire fox. it is free and you do not need to have bought or use any of the other Mc Affee products.
I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following link. http://www.computeractive.co.uk/ On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps.
i use avg, adaware and spybot s%26d all have free versions and are very good.
