Salve ho anche io lo stesso problema con Msn 2009, inizialmente il problema era cvasds0.dll, ho seguito un pò le indicazioni del forum ed è diventato cvasds1.dll, infine fixando cn Hijackthis herss.exe e seguendo tutte le indicazioni su disinstallazione e pulizia, ora l'errore non è scomparso ma si chiama e8main0.dll. Vi prego aiutatemi. Posto il log di hijackthis:
