Which is the best antivirus for a computer?

Hi there,

Instead of all these "Mine is better than yours" answers that go on around here, I'll instead answer with the facts.

Looking at current protection ratings, AVG scores a lowly 90% protection against all known viruses, whilst Avast comes in at 92%. This means they are letting through roughly one in every ten viruses - pretty shocking.

Norton and McAfee are slightly better by protecting against 98.3% and circa 97% respectfully of all known viruses. However, Norton and McAfee can be known for being very heavy programs which can tend to slow down certain machines. If you are thinking of installing either of these I would definitely recommend you download their free trial to check it does not affect your machine in this way prior to opening your wallet.

If you would be interested in other Security products that are better than all of these, you should try either Prevx1, Kaspersky or F-Secure who all score over a 99% protection rating.

Out of these three my recommendation would be Prevx1, as this is the quickest at protecting against new outbreaks of malware.

Personal favorite between Norton and McAfee, it will be McAfee. When it comes to a virus, scanning with McAfee, it detects the latest viruses more times that Norton. Firewall, Norton. It depends on your requirements. Good combination, McAfee with a separate firewall such as Zone Alarms or Comodo.
