Windows Defender Prevented Malicious Software Removal

I wrote this article to help you remove Windows Defender Prevented Malicious Software. This Windows Defender Prevented Malicious Software removal guide works for all Windows versions.

Are you constantly bombarded with the “Windows Defender Prevented Malicious Software” pop-ups? If yes, you are in trouble. You are dealing with a tech support scam, meaning that there is a parasite somewhere on your computer and you have to delete it as soon as possible. On the bright side, the pest you are stuck with is considered relatively easy to remove IF you act fast. Keep in mind that procrastinating won`t solve your problem. On the very contrary. The issues will keep on piling up to the point where it is too late.

Also, the more time the virus spends on board, the more problems it can cause. For instance, it may serve as a backdoor to more infections and compromise your PC even more. Not to mention that, at some point, you may encounter a huge security risk. You don’t even have a single reason to keep this pest on your machine. On the other hand, you have plenty reasons to get rid of it. And the sooner you so do, the better.

As we mentioned, you are dealing with a tech support scam. How does it work, though? It is quite simple actually. Once the virus sneaks into your system you start being flooded with the “Windows Defender Prevented Malicious Software” pop-ups. According to them, you have an “unrecognized and malicious software on your computer”. Now, before you panic, none of this is true. This is why it is called a scam. You don’t have a malicious software on your machine. The only thing to worry about is this nasty infection which is trying to dupe you and steal your money. Of course, it is all about money.

The crooks behind this scam want to scare you and make you believe that your PC is brimming with infections. Then, they offer you a solution. The pop-ups state that you have to enter your Windows product key in order to solve this issues. Needless to say, you have no such key. Then, you are asked to call the 1-877-360-0485 number which, supposedly, will get you in touch with technicians to help you.

Again, this is a lie. You will only contact cybercriminals who will try to sell you some useless anti-malware program and try to convince you that it will help you. If you dial this number, you fall right into the hackers` trap. Do not. Don’t let them trick you and steal your money. Moreover, contacting these people jeopardizes your privacy. This means that your personal and even financial data gets exposed to crooks who won`t think twice before using it for their malicious purposes or selling it to third parties.

If you are particularly unlucky, this can result in financial fraud or even identity theft. That’s why, whatever you do, don’t forget that these pop-ups are fake and don’t dial the number. Yes, the alerts do seem legitimate as the crooks add some deceptive links and use the Windows logo, but you should know better. Ignore the messages and focus on removing the only parasite you actually have – the one displaying the “Windows Defender Prevented Malicious Software” alerts. To do so manually, use our removal guide at the end of this article.

Finally, how did the pest enter and how to prevent another infection? All parasites rely on users` carelessness to help them sneak in. Yes, they turn to tricks to get in, but none of them would ever work without your negligence. If you want to keep your PC infection free, be more cautious. Be on the alert when browsing the Web as it is full of infection waiting for you to do something wrong. So, stay away from shady pages/links/torrents, suspicious pop-ups, fake program updates, spam emails messages, etc.

Also, be extra careful when installing bundles. Hackers know that most users throw caution to the wind when downloading bundles. They rush the process, skip the Terms and Conditions and blindly say “yes” to everything. This strategy is the fastest way to malware. By being distracted and in s rush you miss all the opportunities to spot an intruder on time and prevent it from entering. Don’t be gullible. A little extra time and attention could save you a ton of issues. Caution is your key. Carelessness, on the other hand, is the hackers` key. Don’t grant it.
