Idp.alexa.51 virus removal guide

What is idp.alexa.51?

idp.alexa.51 is a virus/threat detected specifically by Avira, Avast, and AVG anti-virus suites. This malware was first detected in 2016. Note that idp.alexa.51 is not regular malware: it can be an actual infection or a ‘false positive’. Research results show that this threat often infiltrates the system during installation of various Flash games (e.g., Plants vs. Zombies, SeaMonkey, and similar).

A legitimate application might be detected as an idp.alexa.51 threat due to an outdated anti-virus suite database. This is called a false positive. Furthermore, after reading forums, some users may be informed of the ‘false positive’ and then ignore the threat without verifying whether it is genuine. Cyber criminals take advantage of this situation – various potentially unwanted programs (PUPs) and even malware are presented as idp.alexa.51. Potentially unwanted programs typically do three things: 1) deliver intrusive advertisements [adware]; 2) modify web browser options [browser hijackers], and; 3) record sensitive information. Intrusive ads conceal underlying website content (thereby significantly diminishing the browsing experience), but might also lead to malicious sites and execute scripts that stealthily download and install malware. Therefore, even a single click can result in system infection. Browser hijackers modify settings (e.g., new tab URL, default search engine, homepage, and similar) by assigning these options to various URLs (typically, fake web search engines). PUPs are likely to gather information relating to browsing habits (URLs visited, pages viewed, search queries, etc.) Disguised malware, however, might be much more dangerous. It often reduces system performance, misuses resources (e.g., to mine cryptocurrencies), and steals personal data (logins/passwords, banking information, files, etc.) These infections can lead to significant financial losses. Therefore, if you are using Avira, Avast, or AVG suite and it has detected the idp.alexa.51 error, we strongly advise you to take a closer look at the detected file. In addition, scan the system with another reputable anti-spyware suite to ensure that your computer is safe.

idp.alexa.51 shares similarities with Trojan Win32/Tiggre!rfn, FileRepMalware, and many other threats. These viruses are very dangerous. If an anti-virus suite database is outdated, legitimate applications might be detected and even removed. As mentioned above, some forums inform users that these threats are often false-positives. Thus, with this misunderstanding/lack of knowledge, some users might believe that the detected threat (which is malware) is harmless and subsequently do not remove it.

How did idp.alexa.51 infect my computer?

As mentioned above, idp.alexa.51 typically infiltrates systems without permission, since developers promote it as a “bundle” together with other apps (mostly Flash games). Developers know that users often rush download/installation processes and skip steps. Therefore, information regarding idp.alexa.51 infiltration is typically hidden within “Custom/Advanced” settings (or other sections) of these procedures. In some cases, the data is concealed. In any case, skipping download/installation steps simply exposes systems to risk of various infections, thus allowing idp.alexa.51 to infiltrate the system.

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing and downloading and installing software. Select “Custom/Advanced” settings and carefully analyze each window of the download/installation dialogs. Opt-out of all additionally-included programs and decline offers to download/install them. If opting-out is impossible, the entire process should be cancelled immediately. We also strongly recommend that you avoid using third party download/installation tools, since developers monetize them by promoting rogue applications. Your software should be downloaded from official sources only, using direct download links. Having a legitimate anti-virus/anti-spyware installed and running is also paramount. The main reasons for computer infections are poor knowledge and careless behavior – the key to safety is caution. If you believe that your computer is infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate potential threats.
