IDP.ALEXA.51 Virus Trojan horse – a sneaky infection

You probably wonder how you got IDP.ALEXA.51 Virus on your PC in the first place. Well, we would start by saying that such infections happen very sneakily and they are really hard to detect. In fact, Trojan horses are named like that not by chance. These bad guys are really tricky and they infect unsuspecting users in ways and locations where no one even notices them. Trojans like IDP.ALEXA.51 Virus rely on delusive tactics and mask themselves like seemingly harmless files, this way tricking users into clicking on them. This is known more as social engineering tactics that mislead the unsuspecting victims into interacting with the infected payload. Very often Trojans provoke user’s curiosity by camouflaging themselves like some interesting content – files, images, links, ads, offers, email attachments, applications and many more. Once the victim interacts with the content, the harmful script gets immediately activated and introduces the malware right into the system, usually without any symptoms. If you have been infected with a Trojan, you have every right to be concerned about your system’s security and privacy, because such viruses are developed to do literally everything malicious you could think of: from spying on you, to stealing data and credentials, to destroying the system or even introducing Ransomware to your PC.

With its help, people with malicious intentions can gain access to your computer and use it for various criminal deeds and online fraud. Trojans are the hackers’ favorite way to establish remote control over a computer and turn it into a zombie or involve it into a Botnet that loads targeted malware attacks.

Usually, this type of malware tries its best to stay unnoticed and there are hardly any symptoms that can help you detect the infection without good antivirus software. However, there are a few things that victims of IDP.ALEXA.51 Virus may notice during the malware activity. For example, some unusual movements with the cursor of the mouse over the screen may indicate unauthorized access to your machine. Some programs may shut down or open on their own without your interaction or you may notice that your hard drive is loaded with data, though you have not placed anything there. All these may be signs of exploited system vulnerabilities and once you detect any such behavior it is a good idea to fully scan your machine for malware.

Reboot in Safe Mode (use this guide if you don’t know how to do it).

This is the first preparation.


The first thing you absolutely must do is Reveal All Hidden Files and Folders.

  • Do not skip this. IDP.ALEXA.51 Virus may have hidden some of its files and you need to see them.

Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them. If you see a screen like this when you click Uninstall, choose NO:


Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

  • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.



Press CTRL + SHIFT + ESC simultaneously. Go to the Processes Tab. Try to determine which ones are a virus. Google them or ask us in the comments.


  • This step is very important, because you can catch other threats (like Ransomware and Spyware) while looking for the Adware process.

Right click on each of the virus processes separately and select Open File LocationEnd the process after you open the folder, then delete the directories you were sent to.


Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show this way, go manually to these directories and delete/uninstall them:

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
