What is "VIRAL ALARM OF MICROSOFT"?
"VIRAL ALARM OF MICROSOFT" is a fake alert, displayed by deceptive, rogue websites. It is used to scare users into thinking that their computer is blocked, due to a variety of issues. It promotes fraudulent Microsoft Windows technical support, which if used will eventually require payment.
In most cases, such dubious sites are opened by PUAs (potentially unwanted applications) already present in the device. These apps do not need express user permission to be installed onto their systems.
They operate by generating redirects to untrustworthy and potentially malicious websites (for example, ones that display messages like "VIRAL ALARM OF MICROSOFT"), also by delivering intrusive advertisement campaigns and spying on users' browsing activity.
Once accessed, this website displays a pop-up window - an alarm from "Microsoft". This fraudulent alert implores users not to close the window/site and not to restart their computers, due to the registry key being blocked.
Then it lists the reasons why the key is blocked: Windows OS (operating system) was registered using an illegal/pirated key, there is illegitimate software on the system and/or it is spreading viruses over the Internet, the device has been overtaken/hacked from an undefined location.
The scam then continues to urge users to contact its "free" tech support and/or enter the registration key, in order to unblock the computer. Typically, when such fake supports are contacted they take users through meandering paths of technobabble intended to result in users paying for the imaginary services provided.
In short, scams like "VIRAL ALARM OF MICROSOFT" are used to extort money from people. If such fake alerts cannot be closed the usual way (by closing the browser tab/window), the Task Manager should be used to end the browser process.
When reopening the browser in question, the previous session should not be restored - since it will also reopen the scam page (or cause the site that redirected to it before, to do so again).
As previously stated PUAs can force-open new browser tabs/window and redirect users to untrustworthy and potentially malicious websites. They can also run invasive advertisement campaigns (pop-ups, banners, coupons, surveys and similar). By employing a variety of tools, unwanted applications enable third party graphical content.
Consequently, the adverts delivered can seriously diminish browsing quality; limit browsing speed and site visibility (by overlaying the original content).
Additionally, the ads themselves are deemed a safety hazard; due to the type of websites they redirect to (unreliable/compromised/malicious) and their ability to execute scripts, designed to make autonomous downloads/installs of rogue apps. Some PUAs also have data tracking abilities.
By tracking users' browsing habits, they can gather their personal information (IP address, geolocation and real-life identity details). What is important to know, is that this data is then shared with third parties (possibly, cyber criminals), intent on misusing it to generate revenue.
Therefore, PUAs can cause various browser and system invasions/infections, as well as lead to severe privacy issues (even identity theft). To ensure device integrity and user safety, all dubious applications must be removed immediately

PUAs are innumerous and most share certain traits between them. They often offer some sort of "useful" and "advantageous" features. However, most of them are nonfunctional and if not, they rarely operate as advertised. Furthermore, the Internet is rife with various deceitful and scam websites.
They usually display fraudulent system alarms, virus and error alerts, as well as other fake warnings meant to frighten users into paying for having their devices "fixed". Similar scams to "VIRAL ALARM OF MICROSOFT", include "Virus Support Alert", "Windows is not activated", "This computer is blocked" and many others.
Such sites and scams are mostly used by cyber criminals, seeking financial gain through offers of various services or software.
How did potentially unwanted applications install on my computer?
PUAs can be inadvertently installed by users themselves or without their consent/knowledge. Undesirable applications can be downloaded from their websites. They can also be installed alongside intended programs. "Bundling" is a false marketing tactic, by which regular software is pre-packed with PUAs.
Inattentive and rushed installations (e.g. ignoring terms, skipping steps, etc.) can also endanger systems to undesirable invasions. PUAs also proliferate through invasive adverts, which when clicked, can execute scripts to download/uninstall them.
How to avoid installation of potentially unwanted applications?
It is strongly recommended to use only official and verified sources for downloading software, as opposed to third party downloaders. When installing programs, it is advised to read terms and explore possible options, to ensure that the installed programs are legitimate and will behave appropriately.
Additionally, users should use "Custom/Advanced" settings and opt-out from all supplementary apps/features. When browsing, users should refrain from clicking on suspicious ads and avoid visiting likewise suspect websites.
Intrusive advertisements can look ordinary and harmless, however the sites they redirect to (gambling, pornography, adult-dating, etc.) can be a dead giveaway.
Should users encounter such ads/redirects, they are recommended to check their device and remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
