hello, it looks like a library called sprotector.dll (which usually resides in %PROGRAMFILES%\SProtector\) is triggering the crashes. do you know of which program it's a part of? this crash is currently investigated in bug #785940.

Looks like a problem with the sprotector.dll C:\Program Files\SProtector\sprotector.dll

Not sure if this is a legit program or malware:

Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
