"Anti-virus products on the market provide zero protection against new, unreported computer viruses and take weeks to update their signatures to handle such security threats, according to an eye-opening new report from Imperva.
The data center security solution provider called the more than 40 anti-virus software products it tracked for a recent study "woefully inadequate" at protecting IT assets from 82 newly created viruses that company researchers unleashed on them.
Imperva also reported that it took "up to a month or longer" for three-fourths of anti-virus solutions to add those viruses to their signature lists and begin protecting against them.
