![]() ![]() So if something in the system is taking too much CPU, it's way more likely to be a software defect than to be a virus. Trojans are the least-rare form of Mac malware, but even trojans are very rare on macOS. Mac malware is very rare, and viruses are the rarest breed of malware. It's possible that some apps (namely Office, Adobe and other "pro apps" like music production software will store files in other places so keep that Time Machine backup until you're absolutely certain you've everything back up and running. ![]() If some apps don't run, you may have to restore certain folders in ~/Library/Application Support on your Time Machine backup to the Library folder on your clean installation (I'm referring to the Library folder in your home directory, not the one in the root of your hard drive). Once that's done, you can manually restore your stuff from the Time Machine backup including your apps. If you're worried about your apps and documents, back your whole system up using Time Machine then run a clean install of 10.8. I would focus your efforts on fixing the problem before attempting to update using an unsupported hack. ![]() some of your apps may stop working entirely). It might be possible to upgrade beyond 10.8 on an unsupported machine using one of dosdude1's patcher tools but this will likely cause more problems than it solves (ie. Which process is using all your resources and are you sure it's malware? Have you tried force quitting that process using Activity Monitor? What happens when you do? ![]() When I have time and I'm feeling brave I'll go try to hunt down those 3rd party app. This is a good enough fix for me, for now. that's overworking the CPU is suppressed. Apparently it only runs critical library files in safe mode so whatever 3rd party app. The symptoms still occur in OS X, but when I boot in safe mode, they go away completely. I finished a scan running bootcamp and on OS X. I'm going to try some other suggestions and report back. I've tried to run a full scan with Sophos a couple of times now and it always freezes towards the end of a scan. I took a screenshot of the activity monitor and you can see what I'm taking about: I left Sophos running a full scan over night and it's still running this morning! (getting close to being done) It has found several types of malware including Genieo, which is apparently well known for being a pain in the ass to get rid of. I've spent so much time on this with very little progress so any help would be greatly appreciated! I have tried updating the it and 10.8.5 is the highest it will go (maybe there's a way to force it higher?). There are important files and some expensive software that I no longer have the license info for to reinstall them.Īnyways, I've decided to try to remove the virus/malware, but I've searched around for a while now and I can't find ANY anti virus/malware software that will work with this old of an operating system. The original idea was to just wipe the whole drive and start fresh, but it has turned out to be more effort than I first thought. I have a lot of experience with Windows computers but very little with OS X. It also has Bootcamp which runs Windows fine (no virus effects). I'm trying to fix my laptop with a virus that causes the processor to constantly run hot (operating system process takes up 70%+ even just sitting at the desktop not running anything), which makes everything unbearably slow. ![]()
