Antivirus protection worse than a year ago

juct writes: "In a test of 17 antivirus products, the german magazine c't concluded, that the effectiveness has fallen off, and more and more pests can now slip past these barriers. Most of the products perform reasonably well if they can rely on their database of signatures. But if they have to detect new malware with heuristics, the results were worse than last year. Besides this c't did the first comprehensive test of behaviour blocking in antivirus products and found that more than half of them did not react on suspicious behaviour at all. The test itself is available only in the printed magazine, heise Security published a summary."
