A recent report by the AV-Test Institute, found that 66 percent of affected Windows systems are victims of malware that took advantage of exploits found in Adobe Reader, Adobe Flash, and Java.
In a ten plus year study AV-Test uncovered that one exploit for Adobe Reader alone had nearly 37,000 recorded variants that exploited user machines with high levels of precision; users with outdated or known versions of susceptibility stood no virtual chance without some form of protection software.
