Trojan.Agent Virus Unremovable

[supereagan]

Hey, I have a really annoying problem. I have malwarebytes free, and I've removed some viruses on my computer, but the one that stays is trojan.agent. I quick-scanned, restarted my computer after highlighting and clicking remove all, and I scan again, and it's still there. I refused restarting, so that put it into quarantine, but I really want to remove this unless it doesn't do harm while in quarantine. I am using avast internet alongside. This is the log-

That was a false positive. You should be able to restore that. Update Malwarebytes and it will no longer detect that.

Thank you
