IDP.ALEXA.54 Dangerous or Avast (AVG) False Positive?

IDP.ALEXA.54 is the detection of the heuristic engine of your antivirus (like Avast, AVG, or Avira), which may unexpectedly detect this virus. This detection means that it has found something that matches the characteristics of a known or suspected virus, malware, or potentially unwanted program (PUP).


In some cases, “IDP ALEXA 54” detections could be false positives, meaning that Avast or AVG has flagged a harmless file or application as suspicious. False positives can occur due to various reasons, such as outdated virus definitions, heuristics-based scanning, or similarities between the file and known malware patterns.

An Identity Protection Detection (IDP) component of Avast flags your files whenever they perform actions identical to malware that trigger the alert.

If Avast or AVG detects IDP.ALEXA.54, it is advisable to review the specific details provided by another antivirus program (as a second opinion) and adhere to any recommended actions, such as quarantining or removing the flagged files. Furthermore, conducting further research or seeking guidance from your antivirus provider can provide additional information and assistance regarding the handling of this detection.

Is IDP.ALEXA.54 a virus or a false positive detection?

2 days ago I booted up my computer and my AVG popped up a message saying Razer Synapse was infected with IDP.ALEXA.54 This is weird because I haven’t downloaded anything in months and I haven’t hardly used my desktop at home lately since I have been busy. The only when I booted up my computer it did an automatic update to Razer Synapse and that was last week. I had some Windows updates, and my Nvidia graphics card was updated. All about a week or so ago. AVG gave me only 2 options, quarantine or delete. I chose quarantine. It seemed to be showing an executable file with Razer Synapse when it popped up by the way. After I quarantined it I ran a deep scan and it said no viruses were found.Reddit user

Free versions of Avast, AVG, and Avira do not offer the users an automatic database update, as well as not able to remove viruses. Malware is constantly changing, so using an antivirus solution with the databases for 2017 in 2021 was pretty naive. Heuristic engines have this problem even more expressed. Without the updates, this element may falsely detect the elements of legit programs or files, claiming that they are suspicious. Such a “protection” is just a colander for possible viruses, but the danger of outdated bases is not over. Antiviruses with old detection databases often detect legitimate programs because a security tool thinks it is suspicious of its activity. And IDP.ALEXA.54 is one of such cases.

IDP.ALEXA.54 detection

How to IDP.ALEXA.54 virus was detected by Avast

This “virus” may be a part of the program you use every day. It may also be a popular Flash game file called “Lovers” of all false positives. Most of the IDP.ALEXA.54 detections appear during the installation of SeaMonkey or Plants vs. Zombies. These games are 100% legit and do not carry any hazards to your PC. However, as I have already said, you need to be attentive because it is quite easy to miss a hazardous virus. Sometimes, the name ALEXA.54 is assigned to real viruses, usually – browser hijackers or adware.

How dangerous is it?

The list of viruses that can hide under this name is quite big. In most cases, they are browser hijackers and adware, which are not very dangerous if you remove them fast. But several reports are saying that there was spyware and coin miner under this name. Adware and browser hijackers are not very dangerous since they do not make any changes into system settings. You can easily detect that they are inside your PC. The symptoms are strange ads, popup banners, randomly opening browser windows, and search engine changes.

Here is the short review for this threat:
TypeFalse detection, adware, browser hijacker, spyware, coin miner
Reason of appearanceOutdated detection databases of the antivirus tool
Possible sourceSoftware bundles, email spam, malvertising
Removal method
To remove possible virus infections, try to scan your PC

Spyware and coin miners are much more stealthy. Their efficiency depends on the time they were active without detection. Quite a straight motivation to leave no paths in your system, isn’t it? And the damage they may carry is much bigger than adware, even if you remove it as soon as possible. Spyware is just a nuke for your privacy since it collects and passes all possible data about you and your system and then transfers it to its control center. Coin miner is easier to detect since it consumes a huge amount of your computer’s resources. But many users ignore enormous CPU load, blaming the bad hardware or unoptimized Windows OS for the lags.

How did I get this virus?

If IDP.ALEXA.54 is a virus, it can spread differently. But these days, the biggest share of virus distribution is after software bundles, email spamming, and malvertising.

Email spamming became a viral malware distribution method since the users do not raise suspicion on notifications from DHL or Amazon about the incoming delivery. However, it is pretty easy to distinguish the nasty email from the original one. The sender’s email address is a perfect indicator of the “originality” of that letter.

Malicious advertisements on the web, however, are an old-timer of malware distribution. The advice to stop clicking the blinking advertisements on untrustworthy websites exists as long as the ads are on the Internet. You can also install ad-blocking plugins for your web browser – they will deal with any ads.

Software bundling is a widespread practice among virus developers. Users who hack the programs to make them usable without purchasing a license approve any offer to include another program in the pack because they are gaining money in such a way. Check precisely the installation window for signs like “Advanced installation settings” or so. The ability to switch off the malware installation often hides under such items.
