W32.AIDetect.malware2 Trojan


W32.AIDetect.malware2 is a dangerous Trojan horse infection that can be extremely difficult to detect and even more difficult to remove. Unlike other viruses, W32.AIDetect.malware2 does not show any visible symptoms while in the operating system.

The W32.AIDetect.malware2 virus detected by multiple antivirus programs in VirusTotal

This means W32.AIDetect.malware2 can work in complete stealth for an indefinite period of time or until it causes some major system damage or until it completes whatever it’s task might have been. What is more, W32.AIDetect.malware2 (or viruses like Altruistics, Energy.exe) like most Trojan-based infections may mimic legitimate system processes that are already running and, in this way, avoids being detected. Once inside the system, such a threat can be used for a long list of malicious activities. The hackers behind it can use the Trojan to weaken the security of your system and to secretly infect the computer with other malware such as ransomware or spyware. They may also use the infection to steal sensitive information such as passwords, login credentials and banking details, which can later be used for theft, fraud, blackmailing, different scams and more. W32.AIDetect.malware2 may also provide its creators with remote access and allow them to exploit the system’s resources for their criminal activities.

Typically, during the time it operates, it is almost impossible to notice the presence of the Trojan in the system. Yet, sometimes, you may notice that your computer is running slower than usual, programs take longer to open when you try to run them, some parts of legitimate web pages are unavailable and your CPU and RAM usage is higher than usual without any apparent reason.

These may not always be indicators for a possible Trojan horse infection but if you are already bothered by such problems, it is a good idea to conduct a full system scan with reliable antivirus software and remove any suspicious files and components that might be triggering such symptoms. If you use a powerful anti-malware program that has been updated, you should not have any problems removing even W32.AIDetect.malware2 in case you detect it.

How do Trojans infect computers?

According to various computer security specialists, the Trojans spread primarily with the help of malicious email attachments, spam messages, cracked software and fake ads. W32.AIDetect.malware2, in particular, can be accidentally downloaded from illegal webpages that are commonly used to distribute freeware and pirated content. Also, this cyber infection may try to infiltrate your computer through misleading notifications, too-good-to-be-true offers and other similar distribution methods.

That’s why we advise you to avoid emails that tell you of unexpected rewards and profits and ask you to click or download different files and components. Always avoid ads that offer you to upgrade your Flash Player, FLV Player and other similar programs – updates should only be downloaded from the official web pages of the programs. And finally, to be safe and keep your computer protected, it’s a good idea to have professional security software installed on your computer and to update it regularly. This will help you avoid any potential security breaches and will help you prevent future infections with such (or other) malware.

If you need to remove W32.AIDetect.malware2 from your system, we suggest you carefully read the instructions in the removal guide we offer. Be very careful while following the manual steps because, as we said above, the Trojan may mimic important system processes and files which, if stopped or deleted, may cause instability and serious system issues. To avoid additional damage to the system, better use the suggested online scanners and the linked anti-malware tool and in combination with the manual removal steps.

    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.

    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:

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



    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 up this way, go manually to these directories and delete/uninstall them:

    • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
      HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
      HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
