does upgrading system remove malware?
My sophos software failed to clean up a adlware and PUAs alert and recommended manual cleanup - but was unable to locate any of the files named, using the search I'm running OS X 10.7.5 and wasn't going to upgrade just yet, but am wondering if it would sort out this sort of thing automatically?
Many thanks.
