I have the same issue and it began just after updating to Adobe Flash 10. I suggest going to their site as I will do next and reinstall and/or uninstall and go back to the older version.
Can anyone answer this....Is it possible that because I haven't upgraded to IE 8 while allowing the upgrade to Flash 10 cause this?
I've heard too many people complain of IE shutdown issues with IE 8 and so haven't allowed the update. I'm looking forward to hearing the answers to this one because I know of oodles of people with that issue and so am afraid to update, but at the same time I know that several things won't work eventually if I don't.
I'll check back. BTW...I have no malware. I do regular scans, run excellent firewall and antivirus and regular maintenance. On top of that I just had someone who's quite good on pc's look it over and so I'm pretty certain malware isn't my problem.
Thanks, in advance, for any/all assistance.
