Computer Antivirus Software

Antivirus software (antivirus) software used to identify and remove computer viruses

which is free and the best?

I must say that Avast!

I'm using it, it is completely free and you can register on their website for a full membership completely free, although she said the trial.

mc cafee something like that

I promise you, is by far the better it is. It detects and blocks any that Norton and McAfee have tended to ignore. I've been using it for about three years and have no problem. http://download.cnet.com/AVG-Anti-Virus- ...
There is no registration is free (without conditions). It is constantly updated and catches everything.

I am currently using Windows Live One Care. They offer a free trial if you go to their website@www.onecarelive.com
They have a security scanner, cleaning, assistance and support.
You can also make a scan whenever you want.
If you are a subscriber, you can add up to three other PCs in your Circle One Care "
Hope this helps!

try avira
i is the high rate of detection of viruses that avast and avg
but it can not detect sypware if you need to install spyware or as SUPERAntiSpyware Malwarebytes

I used AVG Anti-Virus, ZoneAlarm Firewall, I recently added SUPERAntiSpyware and Malwarebytes. They are all free for personal use and I had no problem with viruses Trojans Hackers etc. I have just upgraded to AVG free 8.0 and all seems good so far. Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from http://www.download.com/ I also use Windows Defender from Microsoft. It is dangerous to use two anti-spy, but never use more than one A / V because it can cause conflicts. You should run A / V and anti spy weekly. Hope this helps
