Where does Erdey.exe come from?

User reports and our own tests also show that this program is mainly spreading with ELEX family browser hijackers. Since these malware infections mostly spread in free software bundles, chances are that this is the most likely way in which you ended up with this infection. It is possible to install malicious bundles after you click on unreliable third-party ads, such as banner and pop-up ads. But do not think for a second that these are always that obvious because some ads may also try to fool you and make you believe that they are something else. In other words, when you are viewing an unfamiliar torrent or freeware website, there is a good chance that you will click on corrupt content, such as fake buttons and links, fake system notifications, and so on. Sometimes, it is enough to click on any area on the page where you cannot even see any content, yet a new window or new tab opens right away with more malicious contents. This is how it is also possible that you download or install a bundle of malware infections even without realizing. This is why it is so important to be aware of the real content of a software package whenever you install one.

Because you may believe that you are only installing your targeted application; however, the bundle may contain a number of threats, such as adware programs, browser hijackers, Trojans, and potentially unwanted applications. You can also drop such a package when you click on questionable third-party ads displayed by adware programs that are residing on your system without your knowledge. All in all, we advise you to delete Erdey.exe from your computer along with all browser hijackers and other potentially harmful programs you may find after you run a proper malware scan on your system.

Certain sources also say that it is possible to install this malicious program via spam e-mails; so it could also spread as an attachment in spams. You need to be very careful every time you open an e-mail because spam mails may not always end up in the spam folder since they may evade detection. But even if they land in your spam folder, they could appear to be very important and convincing so that you would want to open them and save the attachment to see it right away. We recommend that you do not open questionable e-mails coming from unknown or unfamiliar senders.

When this executable starts up, it may operate in the background without your knowledge.

We assume that this program can do certain updating functions but our tests also show that it might show third-party advertisements as well. This could put your system security at risk since cyber criminals can easily exploit it and promote their fake and malicious websites through it. Another risk factor is that when this malicious executable is active on your system, it means that there must be a browser hijacker operating, too. This hijacker can also pose a threat by showing you questionable third-party ads and providing you with potentially unreliable search results that could contain sponsored ads and links that may take you to malicious websites run by cyber criminals. Clicking on corrupt contents is always risky because you may drop infections onto your machine but you could also be deceived by a fake website that poses as a webshop, for instance.
