I'm running Window XP Pro, SP3, with all current critical updates. I'm experiencing degraded system performance, particularly in IE7. IE7 takes 10 seconds to load the home page (regardless of what the home page is set to), 13 seconds to open another tab, performance improves after the 3rd or 4th tab is opened. I'm getting a Windows Live OneCare message a few times a day that says I'm infected with Trojan:Win32/BHO.BO:
OneCare asks if I want to clean this infection, I answer "yes", and it reports that the infection is cleaned, but I'll get the message again in a few hours or less. I've performed a full system scan with OneCare and have run Spybot S&D, both report clean. I've run IE7 in "no add-ons" mode and the performance is the same.
Please help. This is really frustrating.
