However, there have been many questions surrounding the file, as people ask whether Memu-Installer.exe is a virus. This mainly happens when third-party security software detects the installer as malicious. While, in some cases, it might indicate the false-positive, it is important to note that there are several malicious versions of this file – they are usually downloaded from insecure third-party websites.

According to MEmu emulator/Memu-Installer.exe developers Microvirt Software Technology Co., the software allows users to enjoy Android games on Windows computers seemingly for free and possesses multiple advantages:

MEmu allows you to run millions of Android games on your computer, and it has loads of functionality and advantages that will greatly improve the gamer’s enjoyment, such as customizable keymapping, multiple instances, macro keys, operation recorder, etc. Hardcore users may discover the rich functionality by themselves.

However, there are several security concerns about this file. As already mentioned, fake versions can be spread around on malicious websites, so the Memu-Installer.exe virus is a real threat. Therefore, it is advisable to download the installer from the official website only.

The app can also be spread via software bundles, so you might install it without the intention of doing so in the first place. Before you install anything, however, you should ensure that the executable is a signed file, meaning that it is genuine and has not been tampered with. In any case, before you install anything, it is highly recommended to perform a scan with powerful anti-malware, such as SpyHunter 5Combo Cleaner or Malwarebytes. In case you installed a malicious version of the app, these security tools can help you remove Memu-Installer.exe malware from your computer easily.

When looking at the analysis of a legitimate Memu-Installer.exe executable, there are still some concerns. According to the analysis from Virus Total, several applications detect it under the following names:[1]

  • HEUR/AGEN.1138315
  • Trojan.InstallCore.3954
  • Heuristic.HEUR/AGEN.1138315
  • Adware ( 005644ef1 )
  • PUA:Win32/InstallCore
  • Adware.InstallCore, etc.

As evident, many security programs identify it as adware – a type of potentially unwanted program. Based on the heuristic analysis, some vendors even mark it as a Trojan. Looking at the program's behavior, it does not take long to conclude that it indeed performs some suspicious actions once installed on the machine.

For example, it reads the active computer name via the Windows registry and can encrypt the information before sending it over to remote servers.[2] In other words, the app might transfer information in order to monetize on targeted advertisement campaigns – hence it is often detected as adware.

If you are suspicious about the app's behavior, we recommend you proceed with Memu-Installer.exe removal. If you have a malicious version of the program installed, you should perform a full system scan with anti-malware and then attempt to fix the damage done to Windows system files with tools such as FortectIntego.

Avoid downloading software from third party sources

Everybody likes free software, although many forget that it can cost users in other ways. For example, adware programs are known to excessively show advertisements on Google Chrome, Mozilla Firefox, Safari, or other web browsers, all while tracking users' online behavior. Therefore, potentially unwanted programs are essentially never free, as pay-per-click and other advertising monetization schemes are used. Unfortunately, so ad-supported programs perform their actions disregarding users' experience and online safety.

Therefore, you should not install programs that disturb your web browsing sessions and record your online activity – you should be warry of potentially unwanted programs. Here are some tips from experts[3] that would help you to ensure that your computer is safe:

  • Never download pirated programs or software cracks – these are typically used to distribute dangerous malware, such as Mmpa ransomware;
  • Before installing new apps, read about them online;
  • Attempt to avoid third-party websites for your software downloads;
  • During the installation of new apps, always pick Advanced/Custom settings instead of Recommended/Quick ones in order to stay in control of the installation process;
  • Remove all the ticks from pre-ticked checkboxes, read the fine print, watch out for misplaced buttons, etc.;
  • Equip your system with a powerful anti-malware solution that would warn you about incoming threats.

Get rid of Memu-Installer.exe if it did not come from the official developer website

It is up to you to decide whether you want to remove Memu-Installer.exe from your system due to detections by various security vendors. Many apps can be detected as potentially unwanted and not be malicious at all. We believe that the official version of the app is not particularly dangerous, and, as long as you downloaded it from the official website, it should be safe to use. Keep in mind that ads might start interrupting you in some cases.

Memu-Installer.exe removal is necessary if downloaded from less known third-party websites. Keep in mind that any executable can be named as anything – malicious actors often choose to distribute malware via insecure sites where user upload is allowed. With websites such as Softpedia or File Hippo (while these sites bundle software), you can at least be safe that no malware will be downloaded, as they perform security checks before uploading software.

If you are unsure whether Memu-Installer.exe is a virus, simply perform a full system scan with reputable anti-malware tools, such as SpyHunter 5Combo Cleaner or Malwarebytes. Finally, you can fix virus damage easily with the FortectIntego repair tool.
