Recovery partition infected??
CAn the recovery partition on the disk of OS/x 10.9.5 get corrupted with a virus? Have some type of adware virus on the main partition. I rebooted into the recovery partition, used disk utility to erase the contents, and reinstalled OS/x. The NEW installation still shows the virus even when nothing else was done.
OS X Mavericks (10.9), 3.06GHz, Intel Core 2 Duo
