Antivirus programs are software tools which scan through your PC and remove any of the viruses or malware infections that are on your system. It’s often the case that viruses will infect various DLL files on your computer and then cause them to be unreadable to your PC. To ensure this is not happening on your computer, you should try using an antivirus program to scan through your system and remove any of the infections that cause all these errors.
