Which antivirus is best to use with vista

Could you please tell me which antivirus is the best to use with vista. I
am using Norton 360 at the moment but it let in BankerFox.A,
Win32/Nugel.E & Trogan.FakeAV all in one hit so I'm not impressed
Norton sucks, it'a huge resource hog. I like Avira, it's small, light weight, and has much better detection ratings.

1) Antivir PersonalEditionClassic
-Free anti-virus software for Windows.
-Detects and removes more than 50,000 viruses. Free support.
You forgot to say whether you are 32bit or 64bit. For 32 bit there are
more options (Panda Cloud, AVG, Avast!), while for 64-bit only Avira and
Avast! are really recommendable, as they are (partly) 64-bit coded.

But you can´t go wrong with Avira either way
