idp.alexa.51 Avast virus. Full removal guide (Windows/Mac, 2019 update)

removal by Lucia Danes - - | Type: Malware

Idp.alexa.51 is a term used by Avast, AVG or Avira to identify different types of malware, but can also be a false positive

Idp.alexa.51 AVG detecttion name

Idp.alexa.51 is the AV detection reporting about malware hiding in the system. However, this detection can also be a false positive that has nothing to do with risks on your device. To be sure about that, you need to scan the system thoroughly with an alternative anti-virus tool which is not sharing the same virus database. Since IDP.ALEXA.51 virus has mostly been reported by AVG, Avast or Avira AV engines,[1], install another anti-virus to double-check. This intruder is known since 2016 when people started submitting threads asking if this piece of malware is dangerous. Recent reports have shown that IDP.ALEXA.51 alerts could be related to SeaMonkey and Plants vs. Zombies online games, KMSPico, FiveM and MyDailyLife pages.

Name IDP.ALEXA.51
Type  Malware or false positive detection name presented by AVG, Avira, and Avast
OS Windows
Symptoms The malicious example causes system slowdowns, high CPU usage or system crashes. False positives are harmless
Distribution Spreads in a bundle with SeaMonkey, Plants vs. Zombies, EasySpeedUpManager2, KMSPico, MyDailyLIfe, FiveM and other games/apps/websites
Also known as Alexa virus. In case it's not a false positive, the IDP.ALEXA.51 detection refers to a severe cyber infection that has to be removed. 
Elimination We recommend downloading Reimage and running a full system scan with it. 

This detection is primarily associated with online games or apps, such as SeaMonkey, Plants vs. Zombies, EasySpeedUpManager2, and others. The AVG scan results usually report this “file” or detection to stem from the .tmp and .exe files (e.g. swUSB.exe) located in c:\windows\, %appdata% and %temp% folders.

According to the analysis being held a year ago, the IDP.ALEXA.51 malicious detection prevails on the systems running 8.1 located in Portugal and Brazil. However, the extent of this erroneous detection did not decrease and is currently often found on Windows 10 systems running Avira and AVG. In some of the cases, AVG firewall may block the installation of HitMan Pro reporting the HitmanPro.exe as an IDP.ALEXA.51 malware.

Since idp.alexa.51 can be related to various types of malware,[2] note that when AV engines detect this file as a malicious and dangerous one it is possible that the threat can:

  • Download other malware;
  • Use resources of the computer to run additional processes;
  • Give attacker remote access to your device;
  • Deliver advertisements, pop-up messages;
  • Recommend fake updates, promote programs;
  • Redirect to suspicious sites with commercial content;
  • Record keystrokes and information you enter on various websites;
  • Collect and send information about your PC to a remote server or hacker.

IDP.ALEXA.51 virus
IDP.ALEXA.51 virus is malware detection related to Avast, AVG and similar anti-virus software.

The file is related to suspicious malware

Some cybersecurity researchers categorize the IDP.ALEXA.51 file as a Trojan horse or Alexa virus. Although there's no clear evidence for such classification, cybersecurity experts warn that the suspicious detection called IDP.ALEXA.51 might not be a false alarm.

Reputable AV engines like AVG might recognize it as a false-positive detection or threat due to the outdated version running on the system (AVG 8.5, 9.0, 2011, 2012, 2013, 2014 or 2015) or outdated virus database. In 2017, the company acknowledged that this same problem had been triggered by faulty AVG software update.

However, that's not the only reason why AV engine, not necessarily AVG, can report IDP.ALEXA.51 as threat detected in various system's locations. Malware developers can exploit such files or names of the false AV detection to disguise malicious programs or processes.[3] 

IDP.ALEXA.51 even has a few similarities with known trojans and other suspicious detection names like FileRepMalware and TrojanWin32/Tiggre!rfn. You should be aware of many possibilities that this is a virus and scan your device using Reimage, SpyHunter 5Combo Cleaner, or Malwarebytes and see what possible intruders your computer already has installed.

Idp.alexa.51 detection
Idp.alexa.51 is the detection name presented by anti-malware tools that can mean one of the two things - either a need to update anti-virus or a need to remove malware from the system.

Suspicious files come with the system along with freeware

This is not one of the system's files. It is associated with the various application that can be downloaded from the Internet for free. It's not possible to reject the installation of this file-component since it's a part of the software package responsible for its performance.

Although its original version is not considered as malicious, it can be misused by hackers for disguising ad-supported apps, rogue software or even malicious cyber infections. Therefore, each time you install games like Zombie vs. Plants or other free apps, make sure to select the Advanced or Custom installation option and read the terms carefully.

TIP: NoVirus.uk[4] experts recommend people not to let your young children download apps without your intervention as they will undoubtedly skip License Terms and Privacy Policy, thus exposing the system at the risk of being infected with potentially unwanted or malicious programs.

Fix IDP.ALEXA.51 issue and remove the file if needed

In case IDP.ALEXA.51 detection is false, all you have to do is to address your antivirus tool to disable irritating threat detection pop-ups. You can uninstall the anti-virus entirely using its uninstaller on Control Panel and then download the latest version from the official website.

Alternatively, you can check what is the version of your anti-malware tool and download the update for it from the manufacturer's website.

However, we would strongly recommend checking the system with an alternative anti-virus program to make sure that the system is not infected with a hazardous PC infection, such as Trojan, Spyware, Keylogger, and similar. Our top pick tools for an additional scan are Reimage, SpyHunter 5Combo Cleaner, or Malwarebytes.
