Da circa un mese l'apertura delle pagine internet va lentissima (15 - 20 secondi). Faccio presente che ho Alice 20 mega con moden wi fi adsl 2+.
Ho notato in Task manager che la memoria allocata è sempre molto alta e anche aumenta lasciando collegato il pc molto tempo (media di 480 M) mentre l'utilizzo della CPU lo ritengo nella norma. La scheda memoria del pc è di 512. Ancora prima ho dovuto chiamare un tecnico che mi ha riscontrato un probabile virus nella Ram e dopo la formattazione mi ha detto che era tutto a posto (e credo obiettivamente di si). Ho letto da qualche parte che Skype poteva essere una causa di tale lentezza e l'ho disinstallato, avevo inoltre configurato la LAN del modem con el porte di E-mule però adesso leho disattivate.


Ringraziando anticipatamente posto il log di JiackThis pregandovi se possibile di analizzarlo:

Il log non presenta grossi problemi .
Però scarica questi 2 programmi, e li fai girare rigorosamente in MODALITA PROVVISORIA.

http://www.tgsoft.it/italy/download.htm lo aggiorni (cliccando sulla parabola in alto) e lo fai girare in Modalità Provvisoria (è molto importante).
Scarica Norman Malware Cleaner http://download.norman.no/public/Norman_Malware_Cleaner.exe
Norman Malware Cleaner è abbastanza semplice da usare:

Si avvia
si accetta la licenza
si clicca Start Scan
si attende la fine della scansione.
Vedi se hanno rilevato qualcosa.
