What is Microsoft Security Alert?
"Microsoft Security Alert" is a fake error similar to Suspicious Connection, Firewall Breach Detected, Your Computer Is In Blocked State, and many others. "Microsoft Security Alert" is displayed by a malicious website that users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs).
Research shows that, as well as infiltrating systems without consent, PUPs misuse system resources, gather information, and deliver 'malvertising' ads (pop-ups, banners, coupons, etc.)
"Microsoft Security Alert" states that the system is infected and that the user must immediately contact Windows Help Desk (via a telephone number ["+44-800-086-9326"] provided) to resolve this issue. It is stated that if the victim decides to ignore the message, all private details (logins/passwords, banking information, etc.) are compromised.
Be aware, however, that "Microsoft Security Alert" error is fake - merely a scam that has nothing to do with Microsoft (Windows Operating system developers). Cyber criminals claim to be certified technicians and generate revenue by selling their services, which are not needed - the malware simply does not exist.
Furthermore, after calling these people, users will probably be asked to grant remote access to their computers. Once connected, criminals install malware and/or change system settings. They then claim to detect more issues and offer further help for additional fees.
For these reasons, we strongly advise you to ignore the "Microsoft Security Alert" error and never call the aforementioned telephone number. This error can be removed simply by closing the web browser or restarting the system. Some PUPs and malicious websites mine cryptocurrency or run other unwanted processes in the background.
In doing so, these PUPs/websites significantly diminish computer performance. Another downside is information tracking. Potentially unwanted programs often record IP addresses, website URLs visited, pages viewed, search queries, keystrokes, and various other data types that might contain personal details.
This information is later sold to third parties (mostly, for marketing purposes). Furthermore, PUPs deliver various advertisements that conceal underlying website content (thereby diminishing the browsing experience), and might also redirect to malicious websites and/or execute scripts that download/install malware.
For these reasons, potentially unwanted programs must be uninstalled immediately.

As mentioned above, "Microsoft Security Alert" is virtually identical to dozens of other fake errors. All states that the system is infected, missing files or damaged in other ways, however, such claims are merely attempts to scare and trick victims into paying for technical support that is not required. Potentially unwanted programs are also very similar.
Their only purpose is to generate revenue for the developers. Most these apps offer various "useful features". In fact, however, they usually deliver no value for regular users. potentially unwanted programs pose a direct threat to your privacy and Internet browsing safety.
How did adware install on my computer?
In some cases, potentially unwanted programs have official download websites, however, most are distributed using malicious ads and by a deceptive marketing method called "bundling". Thus, due to careless behavior and lack of caution exhibited by many users, PUPs often infiltrate systems without permission.
"Bundling" is stealth installation of third party programs together with regular software/apps. Developers hide "bundled" programs within the "Custom/Advanced" settings, or other sections of the download/installation processes.
Many users rush these processes and skip steps. Furthermore, they often click various ads, thus exposing their systems to risk of various infections and compromising their privacy.
How to avoid installation of potentially unwanted applications?
To prevent system infiltration by PUPs, be very cautious when browsing the Internet and especially when downloading/installing software. Be aware that malicious ads usually appear legitimate, however, most lead to adult dating, pornography, survey, gambling, and other dubious websites.
If you encounter such ads, uninstall all suspicious applications and browser extensions (some PUPS deliver malicious ads). Furthermore, select the "Custom/Advanced" settings, carefully analyze each download/installation step, and opt-out of all additionally-included programs.
In addition, avoid using third party download/installation tools, since they are monetized using the "bundling" method (they promote unwanted software). The key to computer safety is caution.
