which is the best free antivirus if you are trying to save space on your computer?

i know of programs like avg, avast, Malware bytes, and they are all free. But i want to know what is the best free antivirus that is a small(ish) program. i believe my computer has viruses on it, but my space is also low. so i need one that saves some pace on my computer.

For general protection I used to recommend AVG or Avast free editions but I’ve found that Microsoft Security Essentials – http://www.microsoft.com/security_essentials/ – gives just as good protection but is faster and uses less resources.

The test results from tests that AV-Test.org.did returned good for it as well. It found 98.44% of all viruses and trojans, 90.95% of Adware and spyware, 100% of rootkits.

The test at http://news.cnet.com/8301-1009_3-10366232-83.html found that it ws only “average” in speed against other anti-virus programs but personally I found it’s far less intrusive than most.

The use of any of these programs doesn’t mean you can leave common sense behind and click on everything and anything you come across. No security program can be completely safe, as new viruses and variants are developed all the time and this is what makes computers vulnerable to zero-day attacks.

It doesn’t matter if your anti-virus program is free or not, they both offer roughly the same degree of protection, except you get help and support with the paid versions. I’ve had computers that have used the free version AVG for years with no problem and I’ve worked in companies that have McAfee Enterprise Edition and Microsoft ForeFront where computers have become infected.
