IDP.ALEXA.51 – Update May 2019

New reports have emerged in regards of the IDP.ALEXA.51 false positive. It seems that users have been having issues when attempting to play certain video games (Attila, Rome II, Warhammer II). The problem continues to be Avast. One user, for example, has shared in a reddit thread that IDP.ALEXA.51 malware was detected by Avast for the launcher.exe in Warhammer II. Another user has been having similar issues with Attila and Rome II.

The same false positive detection has been happening to users of Taskbar Tweaker. “False positives are unfortunately common for new versions of 7+ Taskbar Tweaker and for beta versions which are less common,” the creater of the program said.

IDP.ALEXA.51 – 2017 Updates

Update May 2017. Unfortunately, AVG users have continued to report issues with the IDP.ALEXA.51 detection. Users are reporting that every time they start their computers the AVG scan interrupts the startup process, wanting to remove the so-called “Alexa Virus”. Even though the security company said it was working on a fix almost a year ago, in July 2016, their customers are continuously dealing with the nagging detection. To be completely sure that you have not been affected by malware or spyware, proceed to the end of the article where you will find more information on defining and removing the issue.

Update June 2017. During the course of 2017 users are still reporting issues of Avast detecting the supposed IDP.ALEXA.51 infection. As we advised you last month, you should pay close attention to the steps given at the bottom of the article so that you eliminate any potential risks associated with IDP.ALEXA.51.

Update July 2017. Few more executable type of files associated with the IDP.ALEXA.51 detection have appeared in the wild. Antivirus vendors have reported that the detection may be a false-positive issue from the antivirus programs themselves, but warn that viruses may pose as such false positive detection and if detected, you should thoroughly remove the files to eliminate any risk.

Update August 2017. The IDP.ALEXA.51 detection is still causing troubles for users who are playing online games like “SeaMonkey” and “Plants vs. Zombies”. Considering that AVG continues to detect it as malicious, it is best to proceed with scanning the system to make sure it’s malware-free.

Update November 2017. In September 2017, the IDP.ALEXA.51 threat is still being detected, most notably on machines running Windows 8.1. Avira and other security programs have detected it in the beginning of the month. Portugal and Brazil seem to be mostly targeted, which doesn’t mean that those are the main target of IDP.ALEXA.51.

How Did I Get IDP.ALEXA.51 Detection

Users over forums have complained that they received the detection message after a restart of the 8.1 Windows version. Reports have arisen on AVG support forums that the antivirus software is displaying a false positive, and they haven’t noticed anything out of the ordinary with their systems, only that it was associated with the following files:

  • Seamonkey.exe
  • Ammsetup(1).tmp

If malware, the software may have arrived in the form of an unwanted download. This may be due to a malicious download, a direct download because of redirect, online message, clicking on a malicious link or a dangerous email attachment in a spam message.

What Does IDP.ALEXA.51 Do

Despite being massively reported as a false positive, AVG experts have provided information that the detection might also be malicious.

In case the detection is malware, it may interfere with the regular work of the system and open up a backdoor, allowing a hacker to access the device from distance and collect information. Other malicious activities associated with this detection might include:

  • Obtaining information directly from the hard disk or using its space as well as the random access memory of the compromised PC. This may result in PC slowdowns and even BSODs (system crash).
  • The erasing of important data on the infected computer, including crucial windows files.
  • Live access from a distance being provided to hackers.
  • Unwanted installation of unauthorized software on the computer.
  • Obtaining other information for advertising purposes.

In case you have experienced any of the above-mentioned symptoms lately, then you may have been infected. Security experts advise affected users to upload suspicious files to VirusTotal for an online scan in case they feel insecure.

IDP.ALEXA.51 – How To Stop It

To stop the IDP.ALEXA.51 detection it is crucial to check whether or not you have malware first. To look for affected files run an on-demand scan with your antivirus program of the folder where the first detection has been encountered. Also, it is recommended to download an advanced anti-malware software that will scan your computer and make sure to remove any intrusions if detected.
