Hi all,

Windows XP prof SP1 with 512MB RAN and a AMD 2GHZ CPU.

Any software that calls ntvdm.exe will hog my CPU. Photoshop, some packages durineg 'file open' etc. I have this since a few days and can not trace back what I did or installed.

Symantec Corp. Antivirus is installed, several Spyware-Cleaner cleaned out minor things, but there is nothing that would be responsible for the first sight.

Someone has a clue for me please?

Mertsch - thanks fgor the reply

My system was fine, up until recent days. I have installed some utilities and apps (NO games!). So either the Registry was modified or a DLL or such was replaced. I had latest updates before and everything was smooth. SP2 will not really solve this, because its more security related.

Google points to the same question I raised on several links. Either paid pages promise an answer (?) or the answers had been very general and no real solutions.
