Random pop-ups appearing then disappearing

Recommended Posts

A few days ago, I mistyped a web address into Firefox and was sent to a website that said my computer was infected with something and I had to do X, Y, and Z to get rid of it.  I instead left the website and did nothing, as both Malware Bytes and Windows Defender came back negative (The website in question is wowsreplays(DOT)com, I meant to go to wowreplays(DOT)com).  Since then, I have had these random pop-ups appear towards the upper-left hand section of my screen, only to disappear the next instant without displaying anything in the pop-up - too quick for me to screencapture.  I have noticed no other symptoms besides this, and the computer is otherwise running fine for the moment.  Attached are the requested logs.  Thank you in advance for any assistance, and I look forward to getting whatever is running in the background of my computer off of my system.

Please see if this may be your issue and let me know.


Please see the following post concerning an hourly popup from a Microsoft Office scheduled task. Credit to ArnoldLayne for information about this issue.

OfficeBackgroundTaskHandlerRegistration flashes a window every hour

Quote by Microsoft employee below


Microsoft’s Gregory Jensen replied: “This issue is fixed starting with build 16.0.8201.2025 which is now available as the latest update for those participating in the Office Insiders Slow program.

“It will be included in a future update for those not participating in Insiders.”

It currently is unclear when exactly the fix will be rolled out for all Office users.

It's very possible.  I do have Office 365 installed, and I am also noticing the same bug on my work computer as well (which has Office installed as well).  Given the problem is fairly widespread, I'm inclined to think this is in fact the problem.  Still, it hasn't hurt to double-check everything.  If you have any other suggestions to try to remove it, I'm all ears.  Otherwise, I suppose I'll wait for a fix from Microsoft and hope the problem ends there.

Following one of those articles you can try setting the scheduled task to happen maybe once a week until Microsoft patches it for everyone. Then see if that removes the popup.

I'll be out most of the day tomorrow but will check back with you late tomorrow night if you do reply.

Great, glad that turned out to be the issue. Hopefully Microsoft will soon release a fix to everyone and not just a select few.

You can go ahead and uninstall or delete any files or tools we've used to scan your system.

Take care
