Anti-virus companies are finding it hard to keep up with the new variant of malicious applications springing up over the Web.
The explosive growth in variant detection is another example of how the Storm worm and other copycat viruses wreaked havoc on IT infrastructure in 2007. As reported by SecurityFocus, F-Secure receives thousands of code samples a day which must be tested and analyzed by a relatively small staff.
The article reports that McAfee and F-Secure have a database of 360,000 and over 500,000 known malware variants so far.
Automating certain aspects of malware detection could go a long way in allaying the concern. As for now, throwing more resources at the detection process seems the only solution.
