Best antivirus?

At the moment I would recommend Avast, Avira and AVG (approximately in that order). I see little advantage in a private person (single user) purchasing any AV solution but I would advise AGAINST having anything to do with Norton AV. They simply use far too much resources (memory and processing time) to be tenable. Probably the least memory-hungry solution will be AVG but Avast and Avira come a close second and currently prove slightly better at detecting viruses. You would certainly be well advised to consider spending money on upgrading your RAM, regardless of what AV solution you have.

You may use Avast Antivirus like me. Home edition is free. You may download it from http://www.avast.com. Register there to get 1 year free license. They shall sent the license key to your mail instantly. You will be able to update your virus database everyday. After 1 year you may register again.

i think avg and bitdefender are good anti-virus where you can find the free edition as well...i proffed many of free security programs but as regards these 2 it seemed to me really ok to stay away for many threats on the net!!

I would recommend what works for me and that is AVAST HOME FREE EDITION. So far I've tried many free antivirus out there but AVAST HOME works pretty well for me. Not to mention it is light on your memory resources and it does not hog your computer memory. The online virus updates really impressed me very well. Besides, the user interface is simple and easy to understand.

I am not a software expert. But I can vouch for McAfee. It has been the best one for me. I have not had any Virus attack since I have installed the McAfee. They are quite cheap too compared to other products in the market. have you tried this one???

avira anytivirus

ive tried various antivirus in my laptop.so i suggest for u 2 use bitdefender IS.compared 2 KIS, it needs less RAM capacity.the interface is quite simple n easy to use.try it..

While I currently am using Mcafee on my laptop at home due to the fact that it came with a year free, the best antivirus I have found is AVG. They offer both free and paid versions, but the free is the best bang for your buck. The only disadvatnage is it can be quite hard to find the free downlaod on their site since obviously they are still in this to make money.

Kaspersky Internet Security i been used about 2 years and i really impressed with it. My advice is use NOD32 i am sure this is suite with your system with 512MB of ram and kinda your pc old one so better use this one or if you want freeware just only AVG free version.

You need to try Avira its the best !!FREE!!! Virus services. Ya its really good and its free.
