I'm having problems surfing internet and working with MS Word (it blocks). I cannot be more precise but very often I cannot close the internet connection. I've already tried to reinstall the os using the recovery cd supplied by Toshiba. It looks like the problems comes after installing the anti virus (AVIRA premium security suite; but before the reinstallation I was using Norton Internet Security with similar problems).Following you can find the error message from event logger than the hijackthis log file: Application: "Applicazione che ha provocato l'errore svchost.exe, versione 5.1.2600.2180, modulo che ha provocato l'errore netapi32.dll, versione 5.1.2600.2180, indirizzo errore 0x0000a3c0."
