Windows Antivirus Failure
The third-party antivirus software for Windows PCs is buckling under the load of advanced security threats, German computer magazine c't reports in its latest issue. A comparison of 17 different antivirus tools show that while a few programs are adept at picking up known trojans viruses, such as AVG and BitDefender, most have seen a degraded ability to recognize malware that does not fit existing patterns. With the exceptions of F-Secure and NOD32, most halved their detection rates of unknown from 40-50 percent in January to just 20-30 percent. This places most Windows PCs at risk of catching a 'wild' virus before the antivirus software firms have a chance to update their signatures to recognize it, c't warns.
