Malware attacks both Mac and Pc versions of Excel

There is a new Trojan horse virus is going around using Microsoft Excel files. It affects both Mac and PC versions of the software though. Named the Trojan.Mdropper.AC it hides in a .xls script file. When Excel opens, the file creates and executable, then that executable runs and allows the hacker to code basically anything he or she wants. That means almost complete control of your computer. The attack only effects the old .xls files, not the .xlsx files that are used in Vista. But, since the new Excel can open the .xls files you should still be careful, Vista users. The versions as old as 2000 are vulnerable and all Mac versions are in danger. Microsoft (of course!) has still not issued a patch to fix the vulnerability, but, hopefully it won't get too out of hand. Mac users should be especially careful since most virus blocking software is ineffective on Mac and many Mac users don't use it.
