Kaspersky prompted me about suspicious activity of StarOpen.sys unknown file. Googled the file, came here and saw Andrew Benn's comment and, as I had just installed Samsung PC Studio 3 mobile phone software (downloaded direct from Samsung), I thought "OK".

Showed up after CDburnerXP program install.
Also on here, installed after SAMSUNG PC Studio was installed, and does no harm. Gets left behind when the STUDIO application is uninstalled.
just came out after install cdburnerXP..
Showed up after CDburnerXP program install [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\StarOpen]
I was wondering about this, I've got CDBurnerXP as well, so most likely harmless.
It caused an error on my Win 7: \SystemRoot\SysWow64\Drivers\StarOpen.SYS has been blocked from loading due to incompatibility with this system.
Inspected content of file sized 77,168 bytes contained the strings "StarOpen CD/DVD/Blu-Ray/HD-DVD access helper driver for Windows NT/2000/XP/2003/Vista/Longhorn" and "Copyright (c) Rocket Division Software 2001-2008. All rights reserved."
CDBurnerXP related, essential file
Know nothing about it but Online Armor Reported it first today and I do have CDBurnerXP installed
I have CDBurnerXP V4.4.1.3099 installed on my Windows XP machine and there is NO StarOpen.sys on C-Drive.

Best practices for resolving StarOpen issues

A clean and tidy computer is the key requirement for avoiding problems with StarOpen. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
