A little slow during scanning is ok and maybe unavoidable but it shouldn't hang. Also during self updates ZA totally hangs.

But ok let's start to build this list.

Antivirus software

1. ZoneAlarm-AV-FW-pay-poor
2. Avast-AV-NA-free-so so
3. TrendMicro-AV-FW-pay-good
4. Symantec-AV-FW-pay-bad
5. Comodo Pro-NA-FW-free-unknown
6. AVG-AV-NA-Free-good
7. NOD32-AV-FW-pay-v.good
8. Sandboxie----pay-???

ok what else is there out there. I'm pretty there's a lot more out there

we need performance status on comodo Pro firewall.

AV
- AVG (free edition) - light on resources - good
- NOD32 (pay) - light on resources - very good

There's also a nice, lightweight, and very efficient anti-malware appl, called Sandboxie, used to be free but not now, which creates an isolation "wall" between a certain application, example your browser and PC's hard drive. Whatever is downloaded from the net, spyware, viruses,... remains in this sandbox, and can be deleted when you close your browser.
It can also be used to isolate other programs as well, which you wish to have them contained, say you want to test a new software. It creates a sort of virtual environment. It's sad that is only for windows.

Sandboxie - (pay) - very light on resources - very good.

i am not infected by winblows and hence don't have to bother about all those listed above

hey shouldn't this thread go in Windows & DOS: Issues & Discussions - The UNIX Forums

I don't know, maybe. Then again, that seems to be more of a discussion of Windoze, not its programs.

Back on topic, I use Avast (free).

AVG has a free option with additional paid for upgrades.
not sure how good/effective it is, i installed it for a pal as a guinea pig . here is link to download... AVG Free - Download AVG Anti-Virus Free Edition for Windows XP and Vista

I added a poll.

If your option is missing, please let us know and we will add it to the poll (let us know if you use the free or paid version, thanks).

I use McAfee. Even though the software is sometimes free, they charge for a subscription to get updates to the virus database.
