which anty virus software is best to install my home pc?

I am using bitdefender software,it is also doing good. PC speed also not got slow,also good against the spywares and virus threats.

Nortan, McAfee are best, but Nortan have some performance issue, so overall i prefer and use McAfee. for more low standards, you can use NOD32

Anti-Virus programs are more of a personal preference. It depends on what you like. i personally prefer McAfee, or Norton. they update the dat files frequently once a week or more often. I am not sure about the others. Once you have a virus protection program and keep it updated you should stay protected.

I'm using a free one AVG8 in combination with a free firewall PCtools Firewall. It work fine with me, my firefox has a addon NoScript a very picky one but I like it that way.

If you use The internet then it is best to install the Norton 360, since it offers complete solution to security as well as gives you 2GB online storage space to store your personal files. If you use your computer locally,then go for the AVG Free Edition, its the best in terms of free anti-virus.

I am using this software only a few days but must to share with you about NOD32 Antivirus System. This program offers integrated, real-time protection against viruses, worms, trojans, spyware, adware, phishing, and hackers. I was using Kaspersky Antivirus program maybe for 2 or 3 years but this is what I was looking for! I’m not sure that there is something like the best antivirus program but this one, NOD32, is the closest you can get:). Very, very easy to work with. I didn’t noticed the slightest slowdown. The operating system is runing like there is no antivirus program. When I was using the Kapersky antivirus, my operating system was throttling. Now working multiple tasks is fully satisfying. Exceptional antivirus, would recommend to anyone. Has passed all tests put forward by the antivirus regulatory committee; (Actually the only one to show a 100% detection rate) and is lightweight and user frendly. What else to say? If anyone wants to try this program is easy. You can purchase on www.eset.com or you can try the free 30-day trial version. It’s easy to download. Just try and when compared with your curent antivirus program you’ll see the results. Just try it. Expecially good for old or slow computers!
