Buhtrap messes with essential system directories and may cause various errors. This, however, is not very likely as this Trojan follows programming to be stealthy. Its main purpose of existence is to open an unnoticeable backdoor to your OS. The news is very bad! The Trojan helps other malware and viruses corrupt your operating system.

How did I get infected with?

Buhtrap travels the Web through malvertising, corrupted links, and malicious websites. The crooks post malicious ads that usually target specific business sectors. They spread ads that promote free downloads of various software, documents, templates, applications, and contracts. The landing websites look professional and legitimate. They, however, offer malicious downloads. As soon as you open their files, the Trojan’s payload infects your OS. Do not give into naivety! The Internet is a dangerous place. You can never know where a virus might strike from. Don’t download files from unknown sources. Take the time to do your due diligence. Do your research. Find reputable, preferably official sources. Even a little extra attention can spare you an avalanche of problems. Bear in mind that a malicious file may make its way to your computer via email as well. Although Buhtrap seems to be spread mainly through malvertising, this virus may also reach your PC through spam messages. Be very careful with your inbox. Whether it’s an instant message or an email, treat all unexpected messages as potential threats. Always verify the senders. If, for example, you receive an email from an organization, go to their official website. Compare the email addresses listed there to the questionable one. If they don’t match, delete the pretender. You can also enter the suspicious addresses into a search engine. If they were used for questionable activities, someone might have complained online!
