Some people use the old adage, you get what you pay for. Well, in this case you might get more for less. Microsoft Security Essentials caught a few viruses that McAfee had missed. All files were verified as being malicious, and they were fairly older exploits. Why they were not added to the virus definition on McAfee is beyond me.
Only 17 of 43 antivirus products detected this as a threat. The full results page showed the identification, if any, for each product on the list. Microsoft, Symantec, Avast, and F-Secure were among the engines that flagged the file. But the majority didn’t. That means one of two things. Either the file was a false positive, and I was about to delete something harmless and perhaps even necessary. Or it was real, and most AV programs were missing it.
