I have been working with SweetTech and this was his final conclusion-
I've had a chance to look into this issue a little more, and have spoken with a couple people in regards to this, and we feel that the issues you are describing are more of a Hardware issue rather than a Virus issue. Because from the look of your logs, they appear to be clean. I think your best option at this point is going to be to post in our Windows forum or Hardware forum and see what the techs have to say. They should be able to help you out with troubleshooting the issue, and try to see if they can pinpoint exactly what is causing the issues.
The symptoms are-
The Alt+Tab feature starts by itself without me pressing any keys. When it starts it acts like the Alt+Tab keys are being held down with each of the program icons in the display being selected in rapid sequence. When it is doing this Iím unable to operate or close those programs or open any other programs or windows. It pops up very randomly and sometimes I can go for days, weeks or even months between episodes. I have not been able to figure out any pattern to the episodes or anything that triggers them. The only way I have found to stop it is to reboot my computer.
The mouse right click menu will suddenly appear and sometimes the courser will dart off to another part of the screen.
Firefox will suddenly start by itself and open to my Home Page. I donít get any strange messages or website redirects.
Microsoft Outlook Setup will suddenly start by itself. I donít use Outlook, I use Thunderbird for email.
Sometimes the Audio Master Volume Control, when I try to move the slider to increase the volume, will just keep drifting back to zero.
I'm using Windows XP Pro with SP3
I always keep my Microsoft Updated.
