Here is my cut and paste for virus threads.
For antivirus NOD32
is the best.
Check it's VB100% record.
23 passes / 3 fails.
It's pricing is comparable to Norton, but for a better product.
21 passes / 6 fails.
3 passes / 19 fails
Avast is also free, and some people think it's better than AVG.
7 passes / 17 fails
is also a good AV. I use the dos based one for pc's behaving badly and won't boot to windows.
is also a very good AV you may want to try.
If you believe you mave have a trojan, try TDS-3
and follow the instructions to manually update the free version. An advantage TDS-3 has over other trojan scanners is it can scan compressed files. No other trojan scanne can do that.
If you think you have a worm try Wormguard.
is also very good, but there is no free demo.
Lately some viruses and trojans have been compromising AV's by locationg their default directories. A way around this is to install security software in a non-default directory, like C:\Safety, or something.
We should really have a sticky with security stuff in it.
AVG is subpar, but for free, you get what you pay for. Avast is better.
You can try Panda online scanner.
If you must have free, Avast is better than AVG but seriously, when it comes to security software like AV's, you get what you pay for.
***FREE PRO ANTI_VIRUS***
You can also get a one year license for free from CA's AV for Free.
Try that out. Better than AVG and Avast.
For firewall, I like Kerio.
It's rules based, so you have to set it up, how you want. But Zone Alarm is fine also. If you use Zone Alarm, might as well use Visual Zone
The above doesn't take into consideration running a linux or bsd firewall or IDS. It just assumes you are a windows user who likes to be safe.
is my friends security page. It has some very good links to a lot of good info. It does need some updating, but it's still useful.
