What is the difference between anti-virus software and internet security suite software?

Is the anti-virus enough?? Or do I need a security suite?? Does the security suite slow down the computer or throw in annoying firewalls that block file sharing programs??

What is the best thing to do?

It seems if I go with a straight antivirus software I should get BitDefender....but Norton if I want a Security Suite....

Some advice would be helpful...thanks..

Security suites tend to slow your computer a lot. Virus.gr did a test on anti-virus programs and Kaspersky v.6 ranked the highest, but the Active Virus Shield by aol is ranked second (well they both ranked the same on percent) anyways Active Virus Shield is based on kaspersky and it's free.The link is below

You can also play it safe with a separate firewall as stated before. Personally I like comodo.

go with a separate anti-virus and a separate firewall

Zonealarm Security suite is the best i think all in one suite!!!

but strong firewall weak anti-virus software
It all depends on what you do with your computer. If you do a lot of downloading and surfing I would suggest at least an anti-virus and spyware program.
