1. Antivir:
[-]:
- No firewall, you need another external firewall
- (has a anyoing sound when finding a virus)
[+]:
- Free
- finds most viruses
McAffee:
[-]:
- Really difficult to configure... a friend of mine used it and it takes about 5 min to disable the firewall
- very expensive.
- As far as I know not as efficient as the other ones
[+]
- All inclusive package, (firewall, spam...)
Kaspersky (I use it)
[-]:
- Not free
[+]:
- Internet security includes everything
- Finds nearly every virus (really good test results)
- Easy to use
(as redscores says there is a free version in the german computer magazine "computerbild" which can do nearly everything the original version can do)
Panda Internet security: (i used to use it)
[-]:
- Extremly high cpu and memory usage (pc speed dropped to half)
- Extremly expensive
[+]:
- Includes everything

I personally preferre Kaspersky.
