Issue: How to fix “Security Error: 0x80070643”?

I’m writing with regard to the “Security Error: 0x80070643” notifications. I noticed a strange pattern that these errors only show up when I’m using my browser. In the message there also an indicated tech support number which I suppose to call to get in touch with a technician who will fix this issue. I am wondering, though, maybe there is a way to get rid of this problem manually? I don’t want to be charged for a job I can, possibly, do myself.

Unlike what some less experienced computer users may think, random occurrences of “Security Error: 0x80070643” pop-ups while browsing online do not signal a critical state of the system’s condition. In fact, they indicate that the device is most likely infected with a Tech Support Scam virus. You may have accidentally admitted this malware on your device after downloading some freeware or shareware application off of the Internet or by installing a fake software update. Regardless of the way your computer has been infected, you should know that Security Error: 0x80070643 is not a real error. In fact, it is not an error at all. It is just a pop up notification generated by this adware-type infection which initial aim is to trick the users into believing that using their computers is no longer safe and continuing it may result in the corruption of their passwords, browser history or credit card information.

Such scams usually provide a “solution” — a phone number (in this case it’s 1-855-999-9246) which the user can call, contact a remote technician and repair any arising issues. In reality, such calls are used by various extortionists for phishing purposes and the attempts to take over computer administration privileges. This can really end up in data corruption, privacy violation and financial loss or even hardware damage. Security Error: 0x80070643 is not an issue that exists, so it does not need to be fixed. Nevertheless, the Tech Support Scam that is causing notifications about this error to appear must be eliminated from the computer immediately. In the guidelines below we explain how this should be done safely.
