I see this with xpsp2 also but I found that this is due to some threat inthe machine not detected by symantec.
filename: gphone.exe
machine: Machine
result: This file is detected as W32.Imaut.E.
I repaired the antivirus and updated with latest rapid release
Virus definition detail:
Sequence Number: 101869 (or higher)
then it detected the threat. and after restarting al is ok now.
