I have a friend who caught his landlord in his apartment using his laptop (he moved out afterward). The next time he tried to log in, his password was changed. I fixed the password problem but I got to thinking, what if his landlord installed some sort of spying software (keylogging, internet monitoring, remotely viewing webcam etc.)?
So my question is if I scan the PC using an offline (kaspersky rescue disk 10) or online malware scanner (Malwarebytes), will they detect spy software? I am under the impression there are legit spying tools that are used for monitoring kids or cheating spouse computers which may be given a free pass by anti malware vendors. Does any such spy software exist which will slip through anti-virus scans? Or is all spy software considered malware and caught by malware scanners?
