How did Kwampirs infiltrate my computer?

Research shows that Kwampirs RAT gets installed through copies legitimate software, it means that cyber criminals distribute this malicious program by compromising networks of software developers. More examples of ways to distribute RATs or other malware are by using email campaigns, fake software updaters, untrustworthy third party software download channels and unofficial software activation tools. It is common that cyber criminals send emails that contain malicious attachments or website links designed to download malicious files. If recipients open those attachments, files, they cause installation of some malicious software. Examples of files that they usually attach to their emails are Microsoft Office documents, PDF documents, archive files, executable files (.exe) and so on. Fake software updaters can infect systems by exploiting bugs, flaws of some outdated software, or/and by installing malware instead of the updates, fixes. Unreliable software download channels like eMule, torrent clients (and other Peer-to-Peer networks), free file hosting and freeware download websites, third party downloaders, unofficial pages, etc., can be used to host malicious files. It means that users who open files downloaded through those channels risk to execute some malicious file that would infect the operating system with some malicious program. Trojans can be designed to cause chain infections. Once installed, they infect computers with some other malicious software. Unofficial activation tools that supposed to activate licensed software for free often are designed to install malware instead. These tools more or less operate like the aforementioned third party updaters.

How to avoid installation of malware?

Irrelevant emails that contain attachments, web links and are sent from unknown, suspicious addresses should not be trusted. Contents of such emails should bot be opened without being sure that it is safe. it is worthwhile to mention that cyber criminals tend to disguise their emails as important, official. Software should bot be downloaded or installed through third party downloaders, installers, unofficial pages and other channels that are mentioned in the paragraph above. Files and programs should be downloaded from official websites and direct links. Furthermore, all installed software must be activated and/or updated with tools that are designed by official developers. Third party, unofficial tools can be designed to install malware. Besides, it is not legal to activate licensed programs with unofficial, 'cracking' tools. Operating systems should be regularly scanned for threats with a reputable antivirus or anti-spyware suite. Also, it is important to make sure that software of this type is always up to date. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.
