Recently I got my computer reformatted, however yesterday my mouse began to act strange. It wouldn't click on things in firefox, or on the desktop at certain points. In order to be able to click anything, I have to minimize the window and restore it. I am not sure whether it's a virus or not, but I have run a Mbam scan and AVG 9.0 with recently updated databases. They came up empty.
After performing a system restore yesterday, it worked fine. However, today it is acting up again, after a reboot.
