Problema con un .dll

[giancai]

Salve a tutti, ho appena eseguito scansioni con vari software sul mio Windows XP Pro, tra cui Malwarebytes, NOD 32 e Spybot, ed all'unanimità appare chiaro che le minacce sono pari a zero. In ultima analisi ho effettuato una scansione con Hijackthis, e dal log è emerso che il problema è causato da:

Vorrei sapere che cosa è questo file, ed orientativamente quali funzioni ricopre; rischio qualcosa sostituendolo con un altro dll identico? O in alternativa cosa posso tentare?

Per maggiori dettagli allego il Log :

La dll che menzioni, ossia la nlsp.dll non fa parte del sisitema operativo, ma di un programma esterno .

In teoria dovrebbe far parte di questo :

http://www.softsol.it/netop.html

che dovrebbe essere NetOp School 6, software shareware che per non creare problemi, come tutti i shareware, deve essere licenziato, ossia installato e registrato ufficialmente

Che problema ti dà ?

Al limite qualsiasi sia il problema, prova a disinstallare il sofware, fai un pò di pulizia e lo reinstalli .



PS: scusa se te lo chiedo, puoi postare un'immagine più piccola ? Grazie
