Eset Nod32 V4 I cannot "enable real-time file system protection"

I Cannot "enable real-time file system protection" It says Non-Functional. I went to setup, Enter entire advanced setup tree..., checked enable real-time file system protection, hit OK and nothing it did not turn on. Tried to click default and nothing. I also ran the On-demand Computer Scan twice. What can the issue be? Please HELP.

any other error messages or issues with comp itself

 

Why would you give him a link for version 3?

 

Posting quickly I guess and the link to 4.0 is at the bottom of previous one

any reason you couldn't post it when you realised ?

 

I posted immediately when I saw it!

 

Thank You that solved the issue Thanks for the proper removal process.

 

What I have noticed about the removal process for version 3.0 and version 4.x is that it is identical. There's no change in the removal process. The only change is in what file to download in order to reinstall. If you kept your previous 4.x download on your hard drive, you could reinstall from that download anyway.
