Fake Windows Defender Prevented Malicious Software Tech Support
Fake Windows Defender Prevented Malicious Software Tech Support is a new malware threat that is hard to miss once it activates itself on your system since it locks your screen with a legitimate-looking blue Windows authentication screen. We have found that this fake alert is very similar to previous threats, including “Microsoft Security essentials +1-888-496-5150” and “Fake Activation Support 1-877-784-7461.” In fact, this is a typical technical support scam that tries to push you to call a provided allegedly technical support telephone number. Obviously, if you are an inexperienced computer user, you would not know suddenly what to do and you may feel that the only way to resolve this situation is to call this phone number (1-877-360-0485). However, you may believe that a Microsoft certified technician will answer the phone, but, instead, a salesperson will whose only aim is to sell you a totally unnecessary application or service to fix a non-existing system error. We suggest that you ignore this fake alert and make sure that you read our full article to learn how you can remove Fake Windows Defender Prevented Malicious Software Tech Support and how you can prevent similar infections from entering your system.
The most likely way for a fake alert to appear on your computer is to download and install a malicious freeware bundle. This is possible mainly in two ways. First of all, you can visit suspicious websites associated with freeware, torrents, and online gaming, and you may feel compelled to click on certain contents on these pages. You may already know that these pages are full of annoying third-party advertisements but you may not have noticed that these ads can be disguised and show up as fake buttons (download, next-page, and previous-page) and different kinds of notifications. The worst case is when you land on a totally unfamiliar website because you will not know where it would be safe to click. If you do not want to infect your system with a whole package of adware programs, browser hijackers, fake alerts, Trojans, and potentially unwanted programs, you should steer clear of questionable websites and clicking on any suspicious third-party content. In this case, it should be obvious that even if you delete Fake Windows Defender Prevented Malicious Software Tech Support, there still could be other malware threats endangering your system.
Another possible way for you to encounter such unreliable third-party ads and links is when your system is already infected with malicious programs, such as adware applications and browser hijackers. These infections can expose you to ads and links coming from cyber criminals. Clicking on these can easily drop a bundle of malicious software installers onto your computer containing this fake alert among other malware threats, but you may well be redirected to malicious websites as well that would do the same. However, no matter how this fake alert entered your system, there is only one thing for you to do right now: You need to delete Fake Windows Defender Prevented Malicious Software Tech Support ASAP.
This fake alert locks your screen with an authentic-looking Windows blue screen that is supposed to be an authentication screen indeed. The reason is allegedly that “Windows Defender prevented an unrecognized and malicious software on your computer.” So you are asked to enter your Windows product key to unlock your Windows. We have found that if you enter “THTY4-89LK6-RTI23-XZTOP-05ERY” and click OK, the screen gets unlocked and you can easily delete Fake Windows Defender Prevented Malicious Software Tech Support. Since this annoying malware program creates a Run registry entry, you cannot even reboot your system in Normal Mode because this fake alert will also start up automatically and will lock your screen every time you restart.
It should be clear that there is no real malware attack claimed by this infection other than itself. Of course, it is possible that your system is swarming with all kinds of adware programs, browser hijackers, and more, but these are definitely not the cause of this screen lock and the supposed authentication process. Therefore, do not rush to find your Windows CD or DVD to enter your product key. In fact, this whole screen lock is about giving you no real choice but to call the alleged "customer support" telephone number, "1-877-360-0485," displayed at the top of your screen. Calling this number could result in your wasting hundreds of dollars on unnecessary software or services. We believe that you should not hesitate to act: Remove Windows Defender Prevented Malicious Software Tech Support from your Windows now.
In order to get rid of the screen lock, you can use the aforementioned key or if you are using Windows 10, you can simply use the Alt+Tab key combination to change the active window and then, close this one. Other than these, you need to restart your system in Safe Mode first. Then, you can delete the related files and registry entries. Please use our guide below for best results. However, it is possible that you are not the manual type of user; therefore, we recommend that you employ a reliable anti-malware program, such as SpyHunter, to keep your PC clean and protected from malicious attacks.
