I just did a scan with Sophos Anti-Rootkit on my computer and it found the following files:
C:\ProgramData\Norton\00000082\00000109\000003c4\c ltLMS1.dat
C:\ProgramData\Norton\00000082\00000109\000003c4\c ltLMS2.dat
C:\Windows\System32\config\SOFTWARE.LOG2
C:\Users\Andreas\AppData\Roaming\SecuROM\UserData\ ЃϵϳЅЂϿϽϯІχϯπρϴϱЄϱЃϵϳЅ
C:\Users\Andreas\AppData\Roaming\SecuROM\UserData\ ЃϵϳЅЂϿϽϯІχϯπρЂϻϵЉЃϵϳЅ
C:\ProgramData\Microsoft\RAC\Temp\sql7697.tmp
C:\ProgramData\Microsoft\RAC\Temp\sql7715.tmp

Not sure if I should clean them up or not.
It says "Removable: Yes (but clean up not recommended for this file)" on all 7.
