Thursday, December 29th, 2005

So, I’ve got most of the baddies cleaned out and I’m not getting popups anymore. No nags on boot, the boot process is quicker, but is it really clean?

Disinfecting a PC… part 9

Thursday, December 22nd, 2005

Ok – about 22 or 23 critical updates for Windows ME. I’m suspecting it’s never visited the Windows update site. While it’s going I make sure that the adware scanners and antivirus scanner get to pull updates from the web as well. It’s also time to scan for running network services that shouldn’t be running.
