I found servicelayer.exe in my perf log and i happen to have a nokia pcsuite installed
This is how to disable the ServiceLayer. If your OS is WinXP do this: Start -- Run -- type services.msc, OR, on Desktop, rightclick My Computer, choose Services. Select (double click) ServiceLayer. On General Tab, go to Service Status and choose STOP. Then go to Startup Type and choose DISABLE. Click OK, and it's done!! NOTE: If you later want to use your Nokia Suite, you must set it back to the original setting, so you need to take a note of the original setting.

Needed for Nokia PC Suite but nothing else

Badly written process that you are forced to run at startup and if you stop it and restart it it doesn't recognize your usb phone anymore.

Best practices for resolving ServiceLayer issues

A clean and tidy computer is the key requirement for avoiding problems with ServiceLayer. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ServiceLayer.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
