Windows 10: Desktop Intrusive Advert - Bottom Right

When another advert appears, open Task Manager and click More Details. Check in the "apps" section for anything suspicious (this is where all open windows appear). may have to sort the processes by name.

 

Are you sure all Web browsers are closed? Check Task Manager as there may be a crashed browser still running invisibly, and pumping ads. If that's all it is, breathe a sigh of relief.

If not, I would be inclined to run the malwarebytes.org scanner over it. Not wishing to raise false alarms but the fact that you have this popup may well indicate a more serious underlying malware problem.

 

Thanks both.

The Dr. Web Cure It is running now. And it's the more serious underlying malware problem that worries me....

And it found nothing.....

 

Can check r programs and features list for any programs that don't remember installing?

 

Uninstall any programs that do not need or recognize, then download ADWCleaner and scan for malware. AdwCleaner Download

If that fails to detect the malware, then scan using an anti-rootkit program. A good one is listed below:
TDSSKiller Download

 

So all scans have so far came back negative (not actually tried TDSSKiller yet) but annoyingly I actually haven't seen another advert, I have no idea what kind of adware shows one pop-up then sits quietly for two weeks. If I knew I would complement them on their design, I guess this isn't as intrusive as I said.
I couldn't find any obscure or unrecognised programs, it's a pretty new pc build with few installed programs which is why I was concerned it may have been a Microsoft thing, glad it isn't though.

Thanks for the help though guys! I'm afraid I have no idea where to go from here so I guess I'll just leave it alone for now.
