An alert box came up that said McAfee had detected FakeAlert-Fake Spy and told me to restart the computer. Upon restart, McAfee scanned the computer and found nothing. McAfee has found several viruses in the past few days, and I am still having issues like being redirected to seemingly random internet pages, or tabs opening on their own with new internet pages. If this was a fake notification, then McAfee isn't finding the cause of it; if it was a real notification, then I don't understand how it found it once and then it can't.
Ironically, I just bought a new computer and this happened as I was backing up the old one to transfer things to the new one, but I don't want to transfer a virus inadvertently.
