I've been having some trouble with my PC lately and realized I could not open my NOD32 Antivirus. I uninstalled and reinstalled it hoping it might be able to find and squash anything I might have picked up, but I'm getting the messages:
"Anti-Phishing protection is non-functional. This functionality is not functional because other required program modules are not active."
"Web and mail protocol filtering is non-functional. The Protocol filtering engine could not be started and your computer is not protected against some internet threats. This is very dangerous and your computer should be restarted immediately."
It doesn't get much more clear or direct than that last line, but despite several restarts I receive the same messages. The Antivirus program itself doesn't seem to have any answers for me - the initial scan turned up clean and I can find no more information on the issues.
Google returns a closed topic from earlier this year (https://forum.eset.com/topic/14449-web-and-mail-protocol-filtering-is-non-functional/) - this has a solution at the very bottom, but the files mentioned return "Installation failed" when I try the suggested solution. Alternatively, I'd be happy to uninstall NOD32 Antivirus, install ESET Internet Security uninstall that, and reinstall NOD32 to send an admin the file mentioned in that thread, but I'd prefer to confirm that's an option before going through that process.
