You know what, it sounds like spyware/adware to me. If he can't connect to the internet, he'll have to download the file from another computer, burn it onto a CR-ROM and then get it over onto his computer: AdAware
He should install it, then run it. Normally I would say "check for updates" but if he can't connect to the internet yet, he won't be able to.
If that doesn't pan out (because he's unable to check for updates first), then maybe he should search his computer for any files named "keenvalue.*" and get rid of them. Then see if he can connect to the internet. If still having problems, then look here:
Plenty of web pages come up on the above search about this parasite, and you will probably find instructions on how to get rid of it there.
