Anti-virus on its own is useless. Viruses aren't coming out as frequent as 10 years ago. Instead those virus writers are switching to malware or ransomware. Making money off someone's less fortunes is the name of the game now.
Getting ahold of a victim's computer, searching for passwords, account information etc. Then if not use the information, sell it off.
Or maybe hijack someone's computer. Pay $200 or the user never sees the information again.
Most AV software outhere [well particularly the free ones] won't even detect malware out there and if they did, they don't know how to clean the computer.
Avast Pro [which had malware "protection"] couldn't even pick up that fake Windows XP Antivirus crap. Microsoft Security Essentials wouldn't find a bunch of trojans....
But finally the biggest problem is the end user. Either they'll click on anything that pops up or don't do anything when a legitimate popup comes around.
