I'm really curious about this. Is it very important to use an antivirus (AV) product? Most of the discussion I've seen in recent months admits to the fact that AV products simply cannot cut the mustard, so to speak. Recent discovery of some piece of malware - don't recall the name - that's been around for five (5) years before it was detected and discussions on various sites lead me to believe that all AV functionality is equivalent to closing the barn door after the livestock have already left. AV, as far as I can tell, provides a false sense of security, but no real security.
Firewalls make sense - if properly configured! - and some of the other security measures seem appropriate at times (sandboxes, encryption, and the like), but I just cannot see the utility of AV products.
When I was in military service, there was a maxim, "You never know how good your security is until it fails and you know it failed!"
I haven't run AV as such for years. I do scan with MalwareBytes on a regular basis and use a firewall - currently Comodo - but no AV.
Is there really any point to AV?
