You trust someone to safeguard you. Yet, they might deceive you. Why? The answer is simple - the money. Fear makes you more susceptible to their protective services, driving up your expenses.
It's like a street gang approaching a shop owner and saying, "We'll keep you safe." The owner might ask, "From what? I have no issues!" The gang's reply is simply, "From trouble."
They scare you with false claims of a virus infection. The more sophisticated antivirus software might identify a file as "suspicious," suggesting potential harm. Yet, they have the authority to label anything as suspicious based on their own criteria. As a user, you're likely to be frightened by the red alert and subscribe to their service, even if there's no real threat.
They can technically suspect anything, but you'll never be sure if there's an actual threat. Even they might not be certain, as they're simply "suspecting."
How to check if they lie or not?
Note file in question, which was marked as infected or "suspicious" by your antivirus. Then, go to VirusTotal and upload that file to check it by over 70 competitive antivirus. What others say?
VirusTotal is a reliable system made many years ago. It checks any file with over 70 antivirus solutions within few seconds. If the file really infected by virus, then, many of them will warn you. But if only 1 antivirus warns you... most likely it is false positive alert. To trick you.
