Three AV companies are well known for producing free and good antivirus:
1- AVG free antivirus (free.avg.com)
It includes antispyware and antivirus. Its detection level is good. It also provides link scanner which doesn't work and is of no use. Its resident shield works good. It scans for viruses, malwares, trojans, browser hijackers, spywares etc.
2- Avira (free-av.com)
Its detection level is much better than AVG, but it doesn't scan for tracking cookies which AVG does. Its resident shield is much better than AVG. Also, it doesn't scan for spywares. It scans for viruses, malwares, trojans, jokes, dialers etc.
3- Avast free (avast.com)
If we look at the media reviews regarding the free antivirus, avast is considered as the best at present. It also doesn't scan for tracking cookies but it scans for trojans and malwares at which other competitors are found too weak. It is pre-set to update automatically.
So, the best free antivirus is avast.
Bitdefender Antivirus Plus at Amazon, Norton AntiVirus at Discount Mountain, and Webroot SecureAnywhere Antivirus 2013 at Webroot are all three considered to be the best anti-virus software available, according to PCMag. All three rated very high at removing malware.
All of the following are available for the Windows platform and provide basic security to the computer. Being free versions, they are lacking something that is available in the paid version. Some of these may be time limited trials. All require periodic updates of virus definitions so that the latest virus programs can be identified. Some recommend that the update is done on a daily basis or before a virus scan is performed.
Popular vendors include:
It is a good idea to read the reviews of experts and independent antivirus test labs.
AV-Comparatives and AV-Test are two independent antivirus test labs which quarterly perform test on antivirus software.
I will leave the other answerers answer in-tact (see bottom)
THe best free anti-virus/anti-malware program out there in Malwarebytes Antimalware. It's completely free, and it detects just short of EVERYTHING possible out there. Plus, if you do pay like 20 bucks USD, then you get real-time protection. In short, Malwarebytes= best out there. 'Nuff said.
I think the best free antivirus is Avira. Because it has in it s virus base over milion signatures and it has very good Heuristic Analyser which can protect from new/"new versions" of Malwares(Virus, Trojan, Worm ...).
But free version of this antivirus will not protect you from Pywareas and adwares. To protect your computer from this Malwares you can use SpywareTerminator or Microsofts Windwos Defender which is also free. I use such security in my computer.
So there are links for this products :
Avira : http://free-av.com SpywareTerminator : http://spywareterminator.com Windows Defender : http://www.microsoft.com/athome/security/spyware/software/default.mspx
Good Luck!

If you are running Windows 7, then Microsoft offers a free antivirus program that is probably the best you can get. If you are running an earlier Windows system, then AVG is your best best. If you are running a Mac or Linux laptop, then no antivirus software is needed. dorothy.wilson8081@yahoo.com
