Scammers that work behind such deceptive projects seek to swindle money from users by telling tales about non-existent computer problems. Typically, they “guide” the victim to go through series of pointless tasks, for instance, open rarely-used folders, touch system settings, type in something in command prompt and initiate other meaningless activities just to confuse the inexperienced user and in the meantime, tell him/her lies that the computer has been compromised. The scammers typically apply one of two strategies to deceive the victim. The first method that they use is to scare the victim and ask him to install a particular computer software, of course, a paid one. Sometimes, scammers urge the victim to provide credit card details to “verify user’s identity,” which is absolute nonsense. Do not let them scam you! The second deceptive strategy is based on persuasion to provide them access to the computer. Scammers ask the victim to install a certain remote administration tool and then tell them login details. Once they get access to the computer, scammers can steal important documents, plant malware, execute ransomware or other malicious viruses, or just delete all victim’s files. Be careful!
