PC users in the U.S. are running a total of 2,720,800,000 vulnerable programs, according to security vendor Secunia. That statistic comes from information gathered through Secunia’s vulnerability scanning tool. Users who scanned their computer using Secunia’s tool for the first time had an average of 12 unpatched programs. Secunia extrapolated from the 227 million internet users in the U.S. to arrive at the total number of vulnerabilities. — AM
