How did I get infected with?

Orcus RAT is promoted as a legitimate remote access tool. You can download it off its official website. Yet, you didn’t do it, did you? The virus appeared out of the blue. Sadly, that’s not the case. The crooks have found a way to spread this virus through spam campaigns. They trick their victims into downloading malicious files. Their scheme is simple, yet very effective. The crooks write on behalf of well-known companies and organizations. They attach malicious files and describe them as important information (such as invoices, offers, job application forms, etc.). And the crooks don’t stop just here. In case you are reluctant to download the attachment, they also embed corrupted links. One click on their hyperlinks and the virus gets on your OS. Do not give into naivety! No anti-virus app can protect you if you act that recklessly. Only your diligence can keep your OS secure and virus-free. 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 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! Even a little extra attention goes a long way!
