Customer has a PC that starts XP, but after a fer minutes, displays: “DCOM process launcher service terminated unexpectedly”, then there is a 30 second countdown before the PC restarts, and the process is repeated again.
After some searching, I find its probably some side-effect of a malware infection.
So I pull out the HDD, connect it to my system, and scan it from my system.
Sure enough, many nasties are found and removed.
Back to the original PC, I work fast in order to disable any possible registry problem related to the malware files having been deleted.
After all that, the PC starts and operates quite normally (for an old pentium 3).
