I am trying to backup my computer to a flash drive using Windows 7's backup and restore feature. It gets part way through and then Microsoft Security Essentials pops up saying it found a virus, Exploit:Java/CVE-2011-3544.B and it stops. I run the anti virus program and it removes the file until I start to do the backup again and it finds the same virus, over and over. The history in MSE says the virus has been removed. Anyone have an idea what I should do?
