Q: URGENT HELP! NEED TO GET RID OF MACKEEPER VIRUS BUT ACCIDENTALLY ALREADY MOVED IT TO TRASH AND EMPTIED TRASH BEFORE KNOWING THAT I NEEDED TO UNINSTALL IT THE RIGHT WAY!

Step one - even before trying to remove MacKeeper - check to see if its been downloaded, "where did that come from?" was my response when I opened my Downloads folder to see MacKeeper 2.1, MacKeeper 1.2, MacKeeper 2.2, MacKeeper 3.2, MacKeeper 4.2, MacKeeper 5.2  packages (.pkg) from May 2014, then MacKeeper 3.3 April 2015.
I zoomed past these looking for a specific download, never actually opened any of the above, and MacKeeper not in Applications.S

Should I still assume that my mac mini will ONLY boot in Safe Mode because it fails Verify Disk every time?

I followed these steps  and found it buried in the activity monitor. I had "uninstalled" it using the application (not effective) and also placed it in the trash. Which wouldn't empty. So...once I hit "Quit" in the activity window it was shut down and I could dump it. Thanks.

Thank you dianeoforegon for the help. But are you sure malwarebytes removed all the viruses 100% because I downloaded it and it told me I have a virus and it removed it. And it told me I must restart my cmputer and I did. Are you sure the virus is deleted? cause if the virus is deleted I would use malwarebytes instead of mcafee.

MalwareBytes for Mac (formerly AdwareMedic) will never report anything it finds as a virus since that's not what it is. It locates and removes adware only. If the app says it removed the adware, then yes, it's gone. That's what the app does.

Mind you, like any such tool, it can only find and remove what it recognizes. If something very new is on your Mac, it may go right past it. The makers of adware are also frequently changing the names of the files they install and where they are installed to on the drive to make any type of removal more difficult. Doesn't matter if you're talking about a utility such as MalwareBytes for Mac, or doing the removal manually. The perps change things, you or the author of the software then need to figure out where the new files are installed.

ok thanks

Will it also delete the folders that I don't need or it will just clean them without deleting them?

i recommend calling Apple support

If the adware created any folders, and its files are the only items in them, then it probably removes those folders too. But even if it doesn't, an empty folder is an empty folder. It's nothing.

You could call Apple, but after running through some removal procedures of their own with you, they often refer callers to MalwareBytes for Mac.

Adware is not a virus but it is as annoying. The biggest threat to your Mac is the User. See this video
