NOD32 is the best anti-virus out there. The price is just right for this wonderful piece of software.
http://www.eset.com is the website. You can try the program out for a while, and I assure you that it’s the best. It’s anti-spyware, anti-adware, anti-virus, and anti-trojan. It also acts as a firewall.
This may seem like an ad, but it’s not. It’s my real opinion.
I used to get a small virus about every month or so, and spyware too. Once, I had this trojan/spyware that was really hard to get rid of, and when I got NOD32 it vanished.
So, if you want free anti-virus software, you aren’t going to find anything like NOD32. AVG is not that good, and it doesn’t even protect against trojans. Spybot: Search and Destroy is ok, but not great (it didn’t get rid of a few nasty pieces of spyware that NOD32 did). Ad-Aware is not that good either, it deleted some important files of mine and I had a lot of trouble fixing the damage.
I have used Norton anti-Virus before, and it’s ok. It’s about half the speed of NOD32, but it does an ok job. The technical support, however, sucks. In fact, Symantec’s technical support is the worst I have ever encountered. And, we bought the software that was described, specifically, to have a license for 2 computers. It was a bit more expensive, so we read carefully to make sure that it was what we thought it was. But, when we tried to install it on both of our computers, it didn’t work. The technical support people were hard to get to, and not very helpful. We finally learned that this version would not work on 2 computers. After having more trouble with the software, we gave it up for good.
And that’s my $0.02.
