What makes a good A/V

When I send a virus sample to antivirus company and after 1 hour the virus info is added to database it's a good antivirus. When I send a virus sample and I receive an automated response and only 1 month later the virus is added to database it's NOT good.
So many paople in the world send new samples to antivirus companies and I see that many companies ignores it.
Despite heuristic, that I believe is very important, the update is important too and the team behind an antivirus software is an important factor.
One more thing: real-time scan is basic...
An Antivirus that have no real-time scan is NOT an antivirus, I think...

 

For me a Good Anti-virus program... should have this features and functions:

- fast automatic updates
- has a Network Shield and Webshield
- will not slow down pc and some other applications
- very advance scanning engine
- w lots of features not found on other brands
- has boot-time scanning to scan the boot sector(some virus might reside in there)
- passed many tests and certified by some reliable testing sites
- fast customer support reply
- compatible w other softwares installed
- w real-time resident protection
- of course... it should be FREE!!!

I found it all in Avast! Home Edition antivirus.
