There may be a tapas server infected, which is highly concerning if this is a consistent issue for multiple people.
I suggest you get ghostery, and Ublock Origin (specifically with that exact name) - wipe all your cookies and history. If you really want to make sure there us nothing left on your PC, backup all important art files that you need, and do a complete factory reset of windows.
Start up in safe mode, and the first thing you do is install your antivirus (don't open any other sites, even better if you have it on disk) and let it update/full search for virusses. Install those two extensions I mentioned before on your browser.
If you have any other PCs, laptops in a wifi/wireless connection, turn them off and do the same for them without connecting it to a network. Things can hide in sneaky connections.
After this napalm bombing of a reset, it should probably be solved.
If it is not, it is either Tapas servers directly spreading this nonsense, or you may have to get a professional store to rid your device of any viruses that hide out in your files.
I hope this helps some of you.
