MCLEAN, Virginia, June 19, 2013 /PRNewswire/ -- In May and the beginning of June 2013, the number of websites infected with malware increased by more than one third: there are currently 34 percent more compromised sites listed in Commtouch's GlobalView™ URL filtering database than in the first quarter of 2013.

The increase follows on the heels of a drastic rise in email spam during the first five months of 2013, much of which is aimed at luring users to malware-infected websites.
