What antivirus is support Window Vista 64Bit ?
I'd found that Kingsoft Internet Security is compatible, but cant install.

Kaspersky Internet Security 2009

dit defender internet security 2009.
RM 95 for 3 license.

Kaspersky Anti-Virus 2009. Running flawlessly on Vista and 7 64-bit. Tested.

avast.. all the way.. and it's free...

AVAST

free of charge???

Kaspersky is not a freeware
the onyl free anti-virus that i know of is AVG, but iianm it is not really a good anti-virus

anyway, if TS looking for commercial anti-virus, i would recommend NOD32 64-bit

using avira only

Kaspersky Anti-Virus 2009 or Avast/AVG for free...

did the Nortan Internet Security 2009 support window vista 64 bit?

Dont worry too much about AV on x64 aren't much viruses (or none significant enough) out in the wild ..other threats exist, but malware, nah...

If you want cheap, get KIS or KAV from Zhen^Wei...Iianm, the KIS key is only Rm18 for 1 year usage =)

Avira can support

Latest Kaspersky and BitDefender will do the job.

if got on9, b sure 2 pick up internet security version...................

avira free only
so far my pc no problem.

Not fully supported, if not mistaken, can't enable certain functions even though NIS '09 has been updated and evne though Vista 64-Bit has been fully updated. PS: I didn't encounter it, a fellow LYNer encountered the problem.

i use avira too..its free and light..but their updater really annoying me..need to update regularly..

sorry i m newbie here >.<
i using NOD32 for vista sp2 64bit it is good?
i new in vista.. pls teach me i willing to learn

i using NOD32 business edition also
Currently works very well, no eat up my ram, no hang, everyday update, scans fast =)

same here =p

Try using Nod32 v4 beta and you will like it.
