Complete IDP.alexa.51 Virus Removal Guide [2021]

IDP.alexa.51 Virus

With over 400 million active Windows 10 users, it looks like a safe bet to many.

But is it?

Windows 10 was released in 2015 and unlike its predecessors, I was hoping it would be a secure OS.

However, over the years, Microsoft has remained impotent in protecting its users from Spywares, Malware, Ransomware, and viruses.

And IDP.ALEXA.51 is one such treatment that has infiltrated systems ever since its detection in 2016.

The IDP.ALEXA.51 virus was 1st detected by Antivirus Software such as Avira, Bitdefender at the time of installing Flash games such as Plants vs Zombies, Kingdom Rush.

So, going ahead in this post, I’ll discuss how your PC gets affected by the IDP.alexa.51 virus, what it does, and what’re precautions you need to take to protect your PC from such threats. Let’s get started:

How do you get the IDP.alexa.51 Virus?

As I said, in the beginning, downloading flash games and web applications such as SeaMonkey & Plants vs. Zombies might play a major role in your PC getting infected by IDP.alexa.51 virus.

However, downloading original games is not the major part of the problem. It’s you who download these games from free websites. In order to exploit your PC, hackers secretly apply IDP.alexa.51 to these applications.

So, next time when you use torrents, free cracked software sites, or even open email think of what you’re compromising. Even if it’s not IDP.alexa.51 there’s always some risk of getting Trojan horses into your PC. All it takes is one malicious executable file to put your complete security at risk.


Now, suppose you’ve allowed IDP.alexa.51 virus to enter into your PC, what does it do?

What are the repercussions of your mistake? Well, here’s a list of things a hacker can do. Things like:

  • Online fraud using your PC.
  • Recording your keystrokes to find your private information. One step further, these keystrokes can be used to identify the password of an Internet Banking account.
  • Download and install other malware into your system.
  • Selling your private information on DARK WEB.
  • Random web page texts can also turn into hyperlinks.
  • Annoying browser popups can shop up to recommend fake updates or even load up 18+ pages.
  • It can transfer information about your systems, such as usernames and browsing history to hackers.

How to Check the IDP.alexa.51 Virus?

You’ve installed Avira, Bitdefender antivirus, or any other popular antivirus but this doesn’t save you from the Virus. The Alexa Virus works like spyware which makes its detection even harder.

And in real-time, you won’t even notice anything bad happening on your PC. Hackers have designed this virus in such a way that it avoids any kind of detection from highly secured antivirus programs. And because of the same reason, you may even notice the  following confirmed issues:

  1. Your PC is slowing down like the old generation computers.
  2. Loss of important files. System files that are important to your PC. And Modern Setup host is one such example of this.
  3. Installation of 3rd party software’s without your permission
  4. High RAM usage without doing any heavy task.

Apart from these suspicious behaviors, you may even end up receiving an unknown message every time you boot your PC.

How to Prevent IDP.alexa.51 Virus?


This phrase is perfect in context with the way you browse the Internet. You need to be super careful when downloading and updating software in your PC.

OR else you would end up with nothing but regrets. Don’t accept invitations to download/install questionable applications. Applications you don’t even need in the 1st place.

Avoid using not-so-reliable third-party software as developers monetize them by injecting supporting fraudulent applications to it. And always download application files from official sources.

Most important of all, you can prevent most of the attacks coming at your PC by installing a popular anti-virus/anti-spyware software.

Even after following all these preventive measures, the only way you’ll get the IDP.alexa.51 virus is your carelessness. Remember, the key to your online protection is vigilance.

How to get rid of Alexa Virus?

If you’ve a good antivirus software than it becomes relatively easy for you to remove the IDP.ALEXA.51 virus.

If you don’t have a budget to buy a premium antivirus than you’re left with the only option of free antivirus. However, in my experience, I’ve never found them to be effective. Instead, I would recommend you to continue using the built-in Microsoft Windows defender.

And don’t forget to update its definitions every now and then. This will help you stay updated from any kind of online threats trying to break into your pc.

Tip: Everytime you update its definition to the latest version, rerun the scanner to see whether you still get the IDP.ALEXA.51 warning.

Even after trying all the quick fix mentioned at the top, the virus still persists, these are the 4 things that you need to apply right away:

Update your Antivirus or its Definitions

When you use an older version or anti-virus or definitions, there are chances that it might detect IDP.ALEXA.51 as false positive.

In the meantime, the virus can seriously f**k up your PC.

So, right after updating everything, it’s important for you to rerun the scan.

This time, the IDP.ALEXA.51 can’t hide from the installed antivirus software (Even if it wants to). Once the virus is detected, take the necessary steps to completely remove the virus from your computer.

Using Microsoft’s Manual Software Removal Tool

It’s quite possible that IDP.ALEXA.51 is injected in software that you rarely even use. So, for this, download Windows Malicious Removal Tool from the Microsoft Store and it’ll uninstall the infected app completely from your PC.

Once the app is uninstalled, rescan your PC, and if your PC is still detecting the IDP.ALEXA.51 virus, restore the PC to the point when the virus was not detected in your PC. However, one thing to note here is that anything you’ve saved after that point, will not return.


I believe this article was informative enough to fix Idp.alexa.51 virus for you. I would sum up this post by recommending you to use an effective antivirus software. Browse the internet smartly and stay away from such viruses and malware in the future.
