Salve a tutti,il mio vecchio portatile IBM, che uso saltuariamente, temo sia stato infettato pur usando antivirus Avira Premium e firewall; il computer marcia lento e a tratti si blocca e all'accensione l'antivirus blocca un programma mi pare"tor.exe". Allego un log di HijackThis che potrebbe dare lumi sul problema. Grazie, Dimi3

Dal log non si vedono infezioni, ci sono un sacco di programmi di scarsa utilità, mi riferisco ai sw Lenovo e poi hai una valanga di programmi in avvio quasi tutti inutili, basterebbe l'antivirus e il firewall gli altri servono solo a rallentare il pc.
Riguardo a tor.exe si tratta di un sw per la navigazione anonima in rete, lo avrai installato tu, se non ti serve lo puoi rimuovere oppure terminare il processo nel task manager.
Per una pulizia fai questa scansione:
Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner
Avvialo e clicca sul pulsante "Scan” finita la scansione clicca su Clean , conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log col Blocco Note.
Copialo e postalo qui.
Ciao.

ADW ha fatto una buona pulizia.
Dunque i programmi che io ritengo di poca o nulla utilità sono le varie utility che le case costruttrici inseriscono, intasano i pc e alle volte creano anche dei conflitti. Ti posso dire quelli che io eliminerei, disinstallandoli, ovviamente sei tu che devi valutare se ti sono utili o meno.

C:\Programmi\Intel\Wireless\Bin\S24EvMon.exe
C:\Programmi\ThinkPad\ConnectUtilities\AcPrfMgrSvc.exe
C:\Programmi\File comuni\Lenovo\tvt_reg_monitor_svc.exe
C:\Programmi\ThinkPad\ConnectUtilities\AcSvc.exe
C:\PROGRA~1\Lenovo\PkgMgr\HOTKEY\TPHKMGR.exe

C:\Programmi\Lenovo\AwayTask\AwaySch.EXE
C:\Programmi\Lenovo\SafeGuard PrivateDisk\pdservice.exe
C:\Programmi\Lenovo\Client Security Solution\cssauth.exe

Ora disattiva le voci in avvio che sono inutili, ovviamente i programmi rimangono.
Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked:

N.B.- Tutte le voci eliminate si possono ripristinare.
Per ripristinare il backup aprire il programma HijackThis e cliccare sul terzo pulsante View the list of backups.
Comparirà una finestra con elencate tutte le righe eliminate, spuntare prima la casellina delle righe che si vogliono ripristinare e quindi cliccare il pulsante Restore. Verrà chiesta una conferma, cliccare su SI.
Fai sapere se il pc è migliorato. Ciao

Apri Ccleaner, Strumenti>disinstallazione, controlla fra le varie voci se trovi quelle che ti ho indicato, poi clic su rimuovi, altrimenti segui il percorso indicato per le varie voci, esempio:
C:\Programmi\Lenovo\SafeGuard PrivateDisk\pdservice.exe, li elimini tutto, file e cartella.
Stessa cosa per le altre.
Se condo me devi avere anche il Registro intasato, ti consiglio un programma molto efficace.

Per fare una pulizia profonda del registro, usa Eusing Free Registry Cleaner sw da usare saltuariamente, lo scarichi da http://www.eusing.com/Download.htm clic su Download Site1, una volta lanciato appare una finestra che chiede il codice, clic su ignora e procedi, in alto a sinistra clic su Analizza Registro, lascia fare fino alla fine non ti preoccupare se trova molte voci poi clicca su Ripara Registro, il sw è sicuro comunque crea un punto di ripristino e fa anche il backup dei file eliminati infatti in alto sotto ripara registro si trova la voce Ripristina Registro, io in anni che lo uso non mi è mai capitato di ripristinare. Ciao

Trattandosi di un vecchio pc meno roba hai installata e meglio è, tienilo pulito spesso con Ccleaner, importante svuotare la cache del browser, poi è importante anche tenere il disco deframmentato, un disco frammentato rallenta tutto. Ciao
