Your antivirus product could be spying on you without you having a clue. It might be intentional but legitimate behavior, yet (malicious) intent is the one step separating antivirus software from a cyber-espionage tool. A perfect one, experts argue.
Because we trust the antivirus to keep us safe from malware, we let it look at all of our files, no questions asked. Regardless of whether personal files or work documents, the antivirus has access to them all, which allows it to work as needed.
We do expect a security product to work in this manner, as most of them have been designed to scan all files on the system to detect any possible threats, and we accept this behavior as being part of our computer’s protection mechanism.
