VIRUS ALERT FROM MICROSOFT is the wide list of scams using the statement that the computer is blocked due to infection. Users get encouraged to call the toll-free number to receive help. However, this is one of the numerous technical support scams[1] pretending to be a real notification from Microsoft. Scammers are trying to convince their victims that their computers will be blocked if they won't contact Microsoft support to solve this issue.

In reality, this Microsoft Inc Warning is nothing but a fake alert used to swindle money from unaware PC users or even open up backdoors for additional hackers and malware. Instead of dialing their given number, you should scan your computer with an anti-virus program. This procedure will help you to get rid of adware which is responsible for showing the fake error message.

Elimination Get a reliable anti-malware tool for adware removal. Try FortectIntego for performing a full system check that can help to clean the machine fully and repair damage

The main purpose of the scam is to convince users to call a fake support line 1-844-808-7462 by telling them that their computers are in real danger. The pop-up message which is used to mislead people typically provides such information:


This computer is BLOCKED

Do not shut down Your Computer and restart your computer
Your computer's registration key is Blocked.
Why we blocked your computer?
Your Computer's registration key is illegal.
Your Computer is using pirated software.
Your Computer is sending virus over the internet.
Your Computer is hacked or used from undefined location.
We block this computer for your security.
Contact Microsoft helpline to reactivate your computer.

Other version displays such warning:

System has been infected by Virus Trojan.worm!055BCCAC9FEC – Personal information (Banking Details, credit cards, and Account Password) may be stolen. System IP Address – is unmasked and can be accessed for virus spreading. Microsoft has reported to the connected ISP to implement a new firewall. Users should call immediately to Technical Support 1-844-507-3556 for free system scan.

Additionally, scammers tell that user’s privacy can be at risk too. The system security alert informs that passwords, messages, credit card information and other personal details have been stolen from the device, and only dialing the “Microsoft Helpline” can help to protect this data.

However, calling authors of the virus scam will cause problems only. Scammers might have numerous scenarios to get your personal information, install malware or gain remote access to your computer. [2] Later on, you might find yourself struggling to receive lost money back or fix severe computer damage after some type of malware attack.

Unfortunately, information obtained during the call might be later used in campaigns like sextortion email attacks. During such, people get tricked into paying the ransom when scammers expose their passwords or real names to prove the danger.[3] However, emails, passwords, and full names can be stolen or leaked in previous incidents.

Additionally, you should not believe that it’s indeed a toll-free phone number that is shown on the alert. It might be just another lie that can literally cost you a lot. Instead of grabbing your phone, you should close the browser’s tab and make sure that you do not have additional adware installed on your PC. Adware might also install other malicious content in the background.

Main signs of the scam

Even though you have the possibility of meeting various scams on unsecured third-party websites, especially, secondary-downloading sources, gambling pages, and similar, typically, the scam starts appearing when an ad-supported application is installed on the computer. This potentially unwanted program (PUP) can be downloaded manually or can infiltrate the target device during freeware[4] or shareware installation.

However, if some adware-type program is the true reason why you are seeing VIRUS ALERT FROM MICROSOFT virus alerts, be prepared to face even more annoying activities. Once inside, the adware virus not only starts redirecting its victim to scammers' website but might also:

  • display aggressive ads;
  • show misleading pop-ups asking to install fake updates;
  • redirect to phishing sites;
  • install suspicious browser add-ons;
  • spy on your activities online.

Therefore, you have to remove VIRUS ALERT FROM MICROSOFT from the computer to protect your browsing sessions. Note that the adware program can be deleted manually. However, it might be a complicated task because it may have installed a bunch of helper objects, extensions or applications that are hard to detect.

For this reason, we recommend automatic adware removal which will help make elimination easier. This method requires scanning the computer with powerful anti-malware software and optimization tools like FortectIntego. Once the AV engine detects all potentially suspicious objects in the machine, you can start performing the elimination process. You can then clean the machine using system software.

The developers only care to receive income from you which can be brought to them in many different ways. For example, if you decide to call the fake number, you will supposedly be asked to provide remote access to your computer system, buy some rogue security products, or reveal some personal information about yourself. All of these actions can lead to negative consequences such as:

  • Identity theft by leaking your personal information;
  • Stealing money straight from your bank account;
  • Placing malware on your computer after gaining remote access to it;
  • Pushing bogus security products for a huge price that will definitely harm your finances.

Adware is commonly distributed in bundles

An ad-supported application which is responsible for redirects to technical support scam website usually spreads as an optional component in freeware or shareware packages. It might be presented as a useful application or browser extension. However, soon after the hijack, it will start bothering you with its intrusive pop-ups and redirects.

Promotional advertisements that push allegedly useful and legitimate programs can also cause automatic downloads and installations of rogue tools. When such processes don't require your permission, you cannot notice the infiltration. To avoid the silent installation of unwanted apps, you have to use Advanced/Custom installation instead of Quick/Recommended settings.

The latter installer does not reveal third-party programs and installs them without asking the user’s permission. Meanwhile, the Advanced installer allows monitoring the processes and opting out additional apps. Besides, you should always keep an eye on what type of websites you are visiting. Make sure that all of them are properly secured and safe to proceed with.

How to prevent from getting malware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
