How dangerous is the Microsoft Security Essentials Alert?

Microsoft Security Essentials Alert virus, otherwise known as Hicurdismos, is a trojan-based infection that pretends to be the official Microsoft’s malware protection product. It easily infiltrates PC systems without authorization and, once it does that, it modifies the computer to boot to a lock screen. In this legitimate-looking but fake BSoD error window, scammers try to imitate a serious system error and encourage the user to call a bogus Microsoft’s support number and get in touch with a professional technician who would supposedly give further instructions on how to fix it. The fake alert is designed to look like the regular Windows BSoD error, so it is not surprising that it may mislead quite a lot of people into thinking that their devices are actually at risk. Besides, hackers also hide the mouse cursor and disable access to the Task Manager, to push users into following their evil plan. Interestingly enough, the virus targets Windows 8 and Windows 10 operating systems though this particular product was initially released for Windows 7 and a few of the earlier OS versions. Please keep in mind that the later versions are equipped with Windows Defender by default, so you do not need to download its earlier nor the later versions. Seeing incompatibilities on your PC is one of the first warning signs that should urge you to consider Microsoft Security Essentials Alert removal immediately. In order to do that without any delay, you can use Reimage.

It is also important to note that this virus is not new. It has been around for a while and evolved into this tech support-ransomware hybrid just quite recently. Previously, the virus was distributed merely as a scareware which locked the PCs to display fake alerts claiming that user was noticed for browsing through websites with infected, copyrighted or pornographic content. This older version of the Microsoft Security Essentials Alert virus is still to be found on the web. Instead of urging you to call the fake tech support, it offers to download and install the special module of the dynamic proactive protection to fix the mentioned issue. Of course, this module is paid. That's how its developers (hackers, scammers, and other bad guys) try to rip their victims off. In addition, this threat may also try to create an image that user needs to update some part of his/hers programs. Either you are infected with the earlier or the later versions of the virus, you have to understand that the pop-up alerts or the BSoD lock screen have nothing to do with Microsoft. Calling the indicated number or purchasing the offered product will not benefit your computer, but rather drive it to a more serious condition. You should ignore these alerts and remove Microsoft Security Essentials Alert which is responsible for causing them.

What causes this malware infection?

This infection can be a cause of careless browsing which is the main way threats like Microsoft Security Essentials Alert virus get inside the system. Clicking or infected links, visiting hacked websites and similar activity should never be practiced if you care about your computer. In addition, you should ignore suspicious emails that may try to trick you into downloading their infected attachments. If this threat infects the system, it locks computer down and displays such notification:

Microsoft Security Essentials Alert

Your system has been blocked for security reason.

Microsoft Security Essentials detected potential threats! Your system has reached the critical security level, because of visiting sites with infected and pornographic contents. Its further use may lead to the system collapse and complete loss of information. To restore Your Windows system performance, you need to download and install an additional module of the dynamic proactive protection. This module is an optional paid update for especially infected Windows systems. It eliminates the causes of system slowdown, associated with the presence of difficult-found malicious software, prevents the system crash and stabilizes its operation.

This is only one variation of fake alerts that this virus is known to deploy on the infected systems. No matter how trustworthy they might look, you must ignore Microsoft Security Essentials Alert ads and lock screens because paying for the shady software or bogus support services will simply lead you to the money and credit card details loss.

You can remove Microsoft Security Essentials Alert in two ways:

Security blogs, websites, and forums offer numerous recommendations on Microsoft Security Essentials Alert removal, so it may sometimes be difficult to distinguish one method that is truly effective. Essentially, there are two virus removal approaches: manual and the automatic one. The manual removal approach is a longer process that might result in the loss of wrong files or even damage to the system if not carried out carefully. Apart from that, it is quite an effective way to remove Microsoft Security Essentials Alert virus from an infected PC. Nevertheless, you can simply run a full system scan with reliable anti-spyware and bypass all the previously mentioned manual removal risks. Anti-malware utilities will remove the threat automatically. If you can't launch these applications, reboot your system into safe mode with networking first.
