Hello,
There can be various reasons for this problem. At first, there was a problem with HTT.
We originally thought HyperThreading only existed on P4 processors of 2.8Ghz or higher, but it turned out that there are slower and older processors with that technology. We suspect something like this to be the problem with Spybot-S&D, since several users have indicated they have no problems with Spybot-S&D and HTT. If you are running Spybot - Search & Destroy on a system that has Hyperthreading Technology (HTT) please read the following thread:

Here is another post that might help:

Could also have something to do with CoolWWWSearch. At this time there is no clear explanation for the CoolWWWSearch.Feat2DLL variant myself, I think there may be malware involved in that one, but it may also be HTT in some cases.
It's fairly obvious at this point that the Central24 and other Dialer hangs are caused by RootKits, often Wareout. There were a couple rare C2.lop/GAIN.Gator hangs early on.
A couple of PCs shutdown or reboot are likely cooling fan problems, especially the laptop. Since we are now aware of the SpeedswitchXP program for mobile CPUs, we have a possible solution for laptops.

I think this summarizes all the major variants we have experienced. If this does not match your problem, please report it to us, so we can soon solve this issue.
