Browser-based tech support scam "warnings" are becoming increasingly more common. They are designed to look official, pretending to be from Microsoft, Google, your internet provider, or another legitimate company.
These messages will claim that your computer is infected, that your data is at risk, or that your computer has been "blocked" because it has been hacked. At the end of their scary warning, they will provide a telephone number and urge you to contact them for support.
There is most likely nothing wrong with your computer.
These are false messages designed specifically to frighten you into contacting the provided fraudulent "support" line, where an individual will attempt to sell you unnecessary support services or software, and will ask to remotely control your computer. By no means should you ever call one of these numbers or let them remotely control your computer.
In the vast majority of cases, there is absolutely nothing wrong with your computer. Unfortunately, the way these browser-based tech support scams are displayed, they can be very difficult and sometimes impossible to close via traditional means.
The following steps will walk you through terminating your browser to clear such messages, and help resolve other problems with pop-ups you may encounter.
When you're unable to close your internet browser the normal way or when it's not safe to close it the normal way, you can forcefully close it.
On a Windows PC
The following steps can be used to terminate any browser, but the examples below will demonstrate using Internet Explorer.
When you next open your browser, if you are asked to restore a session / pages, select No, or close the message.
On a Mac Computer
The following steps can be used to terminate any browser, but the examples below will demonstrate using Safari.
When you next open your browser, if you are asked to restore a session / pages, select No, or close the message.
Extensions provide extra features to Firefox. Sometimes, these Extensions are not coded well, break after a Firefox update, or because they change the way Firefox works in a malicious way to show you advertisements.
Disabling or removing unneeded or unwanted Extensions can help resolve these problems.
It is recommended to delete all unwanted Extensions, then disable all other Extensions, then test the browser, then enable your wanted extensions one by one, testing each time to find the extension that's causing problems.
Disabling an Extension will leave it installed, but entirely deactivated making it do nothing, but easy to re-enable later should you need it. This is best if you're not entirely sure what the extension is for.
It is best to remove any Extensions you see that relate to advertising, or that you know you do not use.
If you are a PST, follow the Escalation Process to PTE.
Unfortunately, your pop-up issue cannot be resolved via basic troubleshooting steps. Your machine will require hands-on service to determine the root cause of your pop-up issues.
