How did I get infected with?

The Quick Searcher CPU Miner Trojan is usually distributed via massive spam email campaigns. The scheme is simple. You receive an email from a well-known organization, company, bank, post office or police department. It looks important, so you open the letter. It contains attachments. Yet, you have heard so many warnings not to open attachments. Luckily, the email contains a link which is supposed to provide more information. You click on it. That is a mistake. You should not click on unverified links. They can be corrupted. Before you take such actions, verify the sender. Simply enter the questionable email address into some search engine. If it was used for shady business, someone might have complained. Yet, this method is not flawless, so, double check the sender. If the questionable email is from an organization, go to their official website. You can find their authorized email addresses there. Compare them with the one you have received a letter from. If they don’t match, you know what to do — delete the trickster immediately. Also, keep in mind that the reliable companies would use your real name to address you. If you receive a message starting with “Dear Friend,” or “Dear Customer,” proceed with caution. A little extra caution can spare you tons of problems. Keeping a trustworthy anti-virus program on board is also a good idea!
