Unable to 'show hidden files or folders'

I cannot 'show hidden files and folders'. I select the option, apply > OK, and the option resets itself.
I think this might be a virus.

Thanks.

*Additional*

My system also appears more sluggish than usual, but I'm not sure if this is connected.

Execute the script in AVPTool:

[CODE]begin
ExecuteRepair(6);
ExecuteRepair(8);
ExecuteRepair(13);
RegKeyIntParamWrite( 'HKLM', 'SOFTWARE\Microsoft\Windows\CurrentVersion\policies\NonEnum', '{BDEADF00-C265-11D0-BCED-00A0C90AB50F}', 1);
RebootWindows(true);
end.[/CODE]
Attach a new [B]avptool_syscheck.zip.[/B]

Ok, I will try this, thanks.

Does this look okay, now that I have executed the script?

I am still not able to view hidden files and folders.
