IDP.ALEXA.51 is false positive by Avast and AVG, but may also be malware
IDP.ALEXA.51 is a name of the suspicious detection reported by reputable AV engines, such as AVG or Avira. People started reporting intrusive AV detection related to this file since 2016, but there's still many reports these days. The AV engine disrupts system's startup and reports the IDP.ALEXA.51 threat or Alexa Virus.
|Type||Malware or false positive caused by AVG and Avast|
|Symptoms||The malicious example causes system slow downs, high CPU usage or system crashes. False positives are harmless|
|Distribution||Spreads in a bundle with SeaMonkey, Plants vs. Zombies, EasySpeedUpManager2, and other games|
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.
The Alexa-related file can be malicious
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Reputable AV engines like AVG might recognize it as a false-positive detection or threat due to the outdated version running on the system (AVG 8.5, 9.0, 2011, 2012, 2013, 2014 or 2015) or outdated virus database.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.
The file comes with the system along with freeware
This file 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 Advanced or Custom installation option and read the terms carefully.
