witch is the best antivirus?

That sounds good for you! At this point of time, I am using avira antivir personal classic edition. I have been using this software for over a longer period of time. Since using it, I have never encountered any problems at all with regards to the overall function and system performance of my machine. Otherwise, I am so impressed and satisfied with its performance. It updates on a regular basis, and this can be scheduled at your most convenient or spare time. It is very light on resources and does not use a lot of memory. Hence, does not slow down your computer. Have a nice day!

The only Antivirus i trust is Bitdefender. i've used it's 9 and 10th versions over 1 year and never had any virus related problems on my PC and i did surf on some dangerous pages and downloaded some dangerous programs but they never got to affect my PC thanks to Bitdefender. Also i would like to say that i've used Norton too and got my PC so infected within 5 days, by simply staying online, that i got to format my hdd. Bitdefender 10 also includes firewall, antispyware and antispam and it's the only antivirus with wich i feel safe.

the best one i ve used so far...(and have used more than you have hair on your head trust me..!!) definately has to be....avast anti virus!!! its really amazing..........its voice automated....and gives out warning bells when a adware of virus is found...!! its an intense an scans all your downloads..... i really like it....and the best part...it doesnt slow your computer or takes up lotsa space.....!!! Cheerz.......^_^

As per my use I have alwaysa used McCafe. It is really good and till now i have not faced any problems. if u r using net u should have really good antivirus like Macafe which scans in real time evry bit downloaded from net....

I prefer Kaspersky although Norton antivirus is powerful but have avital disadvantage (slowing the system).

Even though Kaspersky rocks...i suggest AVG since..it takes very small amount of memory to potect our data...from hackers and virus and spyware

Well im using Nortan anti virus ... nd im quite satify with it ....!!But i like the most is NOD 32 anti virus ..its the best anti virus b'coz it nver slower the system....

i use norton anti virus and avg.
