easy search

[phynx]

ciao a tutti. ho un problema con un laptop con win xp. la macchina risulta infettata da easy search.
vedo che l'infezione centra con una dll chiamata csrss.dll presente in c:\windows. non posso eliminare la dll ma se la rinomino il pc smette di aprirmi alert su alert. ovviamente dopo aver riavviato la dll torna.


posto il log di HijackThis:

qualcuno può suggerirmi cosa eliminare e/o che software usare per ripulire la macchina? grazie
