Check after popup--resolved

I had a popup in Firefox 54.0.1 running on 64-bit Windows 7 at http://3-333x00000z01-virus.com/en/?id=KzEgKDg3NykgNzc3LTg5MDY trying to convince me to download something to get rid of viruses or somesuch–I wasn’t paying attention–and since the sites I had open were probably legit, I’m scanning my computer. Thanks in advance!

Malwarebytes: No threats detected

Posting FRST log as soon as it is available.

FRST scan completed.

If anyone can tell me whether I have any problems, I’d appreciate it; I might not be able to reply until tonight or tomorrow, though.

Logs doesn’t show malware traces and your system seems to be clean. You can safely remove folder at C:\FRST.

Thanks much!
