Remove Insiderdiscover.online Pop-up Virus (Microsoft Support Scam)

Insiderdiscover.online is a deceptive website that displays fake security alerts, which are designed to scare people into calling a remote tech support phone number (0800-090-3289).

Microsoft does not send unsolicited email messages or make unsolicited phone calls to request personal or financial information or fix your computer. Treat all unsolicited phone calls or pop-ups with skepticism. Do not provide any personal information.

These alerts are shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.
Under no circumstances should you call these numbers (0800-090-3289), and if you have already have and purchased services, we advise you to dispute the charges with your credit card company.

The insiderdiscover.online pop-up ads are caused by an adware program which is distributed through various monetization platforms during installation. Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed adware without your knowledge.

When infected with this malicious program, other common symptoms include:

Advertising banners are injected with the web pages that you are visiting.
Random web page text is turned into hyperlinks.
Browser popups appear which recommend fake updates or other software.
Other unwanted adware programs might get installed without the user’s knowledge.

The insiderdiscover.online pop-ups are nothing more than a scam, and you should not purchase anything from numbers listed in these alerts.
Whatever you do, please do not call the phone number for support because it is not Microsoft’s but rather a group of scammers waiting to rob you of hundreds of dollars under false pretenses.

The below instructions are for Windows users, however we also have an Android guide and a Mac OS guide which should help clean up your device.
