Well, I doubt this is the right board to put this topic into, but let's give it a shot.

I've tried downloading Invisible Keylogger for my son's PC so I can monitor what sites he visits. Problem is, every time I go to download Invisible Keylogger a dialog box pops up and says "An error occured while coping file C:\Windows\Temp\RarSFX2\nvsr32.exe to C:\Program Files\Invisible Keylogger\nvrs32.exe. To retry copying press "Retry" System error message: Access is denied.

What should I do?

I've just tried to download Invisible Keylogger from Shareup and it came up with a virus alert. I've just tried another site and the same thing happened there. Is Invisible Keylogger worth having?

I've just done another search for "Invisible Keylogger" +download +virus and they report a virus in this download, so for get it.

Well then what should I download to monitor him? There must be something, I can't be by his side all day.

You could either put up a firewall to censor all inappropiate sites, or merely block some sites. (Don't ask me how to do this, I'm not entirely sure how.)

If you want to monitor EXACTLY what sites he visits, i'm not sure, perhaps you could try a different keylogger if there is one out there.
Correct me if I'm wrong, but keyloggers are also used as malware in phishing, so therefore are detected by anti-viruses as malware and removes it.

Which operating sytem is your son's computer using, and which version?
