Ok well i uninstalled the yahoo and i'll try to rescan with spybot and let you know how it goes. Last night my internet brower suddenly closed i and recieved an error saying it had suddenly stopped responding. right after that i recieved an error saying drwatson postmortem debugger has encountered an error and needed to close.
OK, that's because we skipped most of the scans ahead of the group contianing C2.lop which avoided the issue somehow, which I thought might happen.
How much more time we spend on this depends mostly on you, since you'll need to perform the experiments. There's still a couple theories that fit, though this seems to have at least partially proven them.
The fact that you can test through the Spybots.sbi detections containing C2.lop seems to indicate that it isn't these detections themselves that are failing, since they're no longer freezing at that point. This also makes it unlikely that some other specific anti-malware program is interfering like Yahoo appeared to be.
However, it is still possible, though unlikely that another previous detection is helping 'set up' for the C2.lop freeze to occur. The only way I can see to confirm this is to contimue to add back in the other detections tests by working backwards and checking each .sbi file one at a time and running a scan.
Once it does freeze, and I believe it eventually will, try unckecking all tests except the last one checked that 'triggered' the freeze and the Spybots.sbi itself of course. If this still freezes, try one last test please. Turn off the computer, leave it for a half hour (dinner time) come back and re-run that test one more time. We want to know if it's really just the two .sbi groups, all of them together or just a build-up over time that's creating this.
As I said, a bit of work on your part, but you only need to return and post after you've tried most or all of it. Jot down results so you remember them and especially let us know if anything un-expected happens like freezing in some other detection. You've done a great job of indicating exactly where it's freezing to this point.
Thanks for helping track this down.
Oh, one other thing, something I meant to ask that I forgot. What exactly are the specs of your computer; CPU & Speed, RAM, is it XP Home or Pro?
There is not a problem with me doing what you just mentioned. Its XP home edition CPU is 2.80ghz 512mb of ram and i believe the speed is 2.80ghz as well (system properties) I'll check those scans out and get back to you.
