I'd follow the advice given in http://www.annoyances.org/exec/forum/winxp/t1035511537 : turn off indexing service. In fact, I had already done it on my new XP machine. I don't think I need the results. Do you rely heavily on it?
And, of course, this is a typical background process. Why it misbehaves isn't clear. Time to call Microsofts support team, as advised? There's nothing about cideamon on the MSKB, except a Japanese article about it using 100% of the CPU.
This is the alert window that I get every few seconds, or minutes:
"Microsoft Visual C++ Runtime Library Error
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."
I always get this message, even if I didn't start any application. There is no software that runs at background, I checked it all.
I tried with antiviruses, anti-spy softwares, HijackThis, stoping this indexing service... Even if I delete cidaemon.exe, Windows makes another copy.
I don't know what application makes this error, since I haven't installed anything new.
I am running Windows XP Pro SP2,CPU Intel 3GHz, 786 MB DDRAM...
