nb.exe | ThreatExpert statistics might be of help, ... "nb.exe is used by 'Notesbrowser'.This is an application created by 'Wave Digital Studios GmbH'. To stop nb.exe permanently uninstall 'Notesbrowser' from your system." is one option i noted. do you have a good antivirus program installed? you could run an online scan dfrom eset-nod, a one-time scan is free: http://www.eset.com/us/online-scanner/

1st: nb.exe is a bad thing.

2nd: Get a better AV software like Microsoft Security Essentials.
