services.exe e svchost.exe

[viviana76]

Ciao a tutte e tutti,
da qualche giorno il mio pc (un hp con S.O xp) mi dai dei problemi di connessione. Il firewall (Comodo) rileva dei tentativi di connessione da parte di questi processi:
spoolsv.exe
services.exe
mgsvc.exe
wmpnetwk.exe
alg.exe
svchost.exe

non sono sicura che le cose siano collegate ma facendo un giro sui vari forum ho visto che sia services.exe che svchost.exe potrebbero essere pericolosi.

Vi allego il log hijackthis che fatto sperando che qualcuno possa darmi dei consigli!
Grazie
Viv

[hell's bells]

Dal log si vede questo C:\WINDOWS\svchost.exe il file di per se puo' sembrare legittimo ma la posizione non è corretta, quindi per prudenza fixiamo la voce, poi eseguiamo un controllo sul file

verifica che hijackthis sia installato in una cartella apposita c:\programmi\hijackthis

rilancia hijackthis, clicca su "do a system scan only", poi a destra in basso clicca su config, assicurati che ci sia il segno di spunta sulla casella "make backups before fixing items" clicca su back e metti il segno di spunta o flag in corrispondenza di questa

O23 - Service: Distributed Link Tracking Servers (TrkNetsSvcs) - Unknown owner - C:\WINDOWS\svchost.exe (file missing)

Poi fai una ricerca nella cartella c:\windows e verifica se il file è ancora presente visto che viene segnalato come missing.

Per la mia scarsa conoscenza non rilevo altro dal tuo log.
