Min dator hänger sig hela tiden!!!!

Kan någon hjälpa mig?

För några dagar sedan började min dator bete sig konstigt. Webläsaren funkar inte som den ska. vissa sidor kommer inte fram och kan då göra så att explorer hänger sig, detta sker även när jag ska dra ner "rullgardinen på adressfältet" då kommer en ruta med windows har upptäckt ett fel, vill du att skicka meddelande till .... detta händer även ofta när jag inte surfar och bara öppnar en katalog eller ska söka efter en fil. när jag ska stänga av datorn kommer detta ruta upp MPDB_MGR_WND och då måste jag trycka mannuellt på end knappen.
Det här är min hijackthis log om det nu hjälper:
