Is idp.alexa.53 a virus or a false positive detection?

Free versions of Avast, AVG, and Avira do not offer the users an automatic database update, as well as not being able to remove viruses. Malware is a constantly changing, so it was pretty naive to use an antivirus solution with the databases for 2017 in 2021. 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 Such a “protection” is just a colander for possible viruses, but the danger of outdated bases is not over.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 legit programs because a security tool thinks it is suspicious of its activity. And idp.alexa.53 is exactly this case.

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.53 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 idp.alexa.53 is assigned to real viruses, usually – browser hijackers or adware.

How dangerous is the idp.alexa.53 virus?

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 will 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 appeared lags.

How did I get this virus?

If Idp.alexa.53 is a virus, it may be 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 email address of the sender is a perfect indicator of the “originality” of that letter.

Malicious advertisements on the web, however, is an old-timer of malware distribution1. And 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 the 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.

What do I need to do with this “virus”?

To be sure if the idp.alexa.53 virus is a false detection of a legit or real program. It would be best if you had anti-malware software. Free AVG, Avast, and Avira variants are scanners that cannot remove viruses and perform proactive protection. As was mentioned several times, this detect name is typical for false positives, as well as for various viruses. If you have the symptoms I have described in previous paragraphs, check your computer with anti-malware software. My choice for the case of IDP.alexa.53 is GridinSoft Anti-Malware2. Its databases are constantly updating, and it has malware removal functions and proactive protection.
