Free Antivirus software Download

Antivirus is one of the most essential software for computer nowadays. Most of the software doesn't come cheap and you'd have to renew your subscription every year at a fees just to download the latest virus definition. I've tried numerous anti-viruses software both paid and free, and I've to say I don't really see any difference between them. The paid version I used were Norton, one of the biggest antivirus software company on the net. Is it any good? Well.. it's just ok. I've decided to stop using it 2 years ago after messing with some free antivirus software. And the fact that Norton software is a resources hog that will slow down any super computers. But the real problem here is, Norton is a decent antivirus software, but it's not perfect. It doesn't detect every virus that are infected on your PC even with the newest definition, while others free software detected it. This doesn't mean that a free version is actually better, I tried many different antivirus software with various result. Some software detected a virus while others don't, and while others detected a virus and some don't. In short, I haven't found the best antivirus software yet that detect every viruses.

Before you invest in antivirus software, I highly recommend you to use a firewall. A firewall will protect you from virus, spyware and adware on other site and block them from accessing your computer. This will greatly reduce your chance of getting infected with unecessary adware. The best firewall I have uses so far are zonealarm. I think there's a free version of zonealarm available on the official site. If you like it, buy the full version for more advanced protection against malware. Firewalls are especially useful against blocking internet and suspicious program from running on the background. But still you need an antivirus software to make sure your PC's are clean.

You don't really have to pay for an antivirus software. There's some free antivirus software you can download on the interenet and it provides good enough virus protection, at least comparing to the pay version. The one I'm currently using are AVS, I heard that avast are not bad as well. These companies provide very frequent virus database update. You can either set it to automatically update or you can download the virus definition on the official site and update manually.

Although these softwares does a fine job, they are not perfect. If you are downloading files from unknown sources, p2p or torrent, make sure you scan all the files before opening it. Another dangerous sources are from email attached, even if it's sent by your friends, you should check the file and make sure it's clean before downloading it. Your friend might be forwarding attachment file that contain viruses without knowing it. Be a little bit more careful and your PC will be cleaned from viruses.
