Allora, non riesco a risolvere questo problema dello scorrimento autonomo delle pagine in cui mi trovo, indifferentemente se internet o di un ebook. Ad esempio, poco fa avevo calibre aperto per leggere un ebook e le pagine andavano su e giù senza che fossero toccati tastiera o mouse. Poi spostando la pagina con il mouse, facevano come "resistenza" riposizionandosi dov'erano prima e rifacendo su e giù come impazzite. Eppure avevo fatto AdwCleaner con conseguente bella pulizia e anche Junk Removal, ma questo fatto non si è risolto, anzi mi è comparso un fenomeno nuovo: spesso pigiando la barra spaziatrice vengono fuori 3 spazi.
Potete aiutarmi per favore?

Intanto posto i logs dei summenzionati programmi

Grazie misterboss, aspetterò che qualcun altro mi aiuti anche perchè mi fa anche un altro scherzetto: mi fa oltre il doppio/triplo spazio, la doppia s, mi salta di uno spazio mentre scrivo e tante altre cosette con la tastiera. Da che dipende? Boh!

Il tuo problema non credo sia legato a qualche virus, potrebbe esserci qualche conflitto che crea il malfunzionamento dei tasti della tastiera, prova a dare una bella soffiata con una bomboletta d'aria compressa attorno a tutti i tasti, fa sempre bene, se hai una tastiera senza fili controlla che le batterie non siano esaurite.
Fai una scansione con QUESTO programma, é un sw che ripara molti problemi di windows. Una volta scaricato clicca sull'eseguibile, devi chiudere tutti i programmi compreso il browser, poi clic su Accetto e dopo clic su Avvia, attendi che parta la scansione, lascia fare fino alla fine senza interferire, finito devi riavviare il pc, il programma non rilascia nessun log.
Hai dei problemi di RAM ? con XP devi avere come minimo 1Gb meglio se sono 2Gb.
Il log HJT non presenta problemi, ci sono solo troppe voci in avvio inutili.
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:

Poi fai una pulizia con Ccleaner compreso il Registro, per il Registro spunta tutte le voci acconsenti al backup quando richiesto, sempre in Ccleaner vai in Strumenti Ripristino Sistema seleziona tutte le voci tranne l'ultima che non è selezionabile e rimane per sicurezza, poi clic su Rimuovi.
Fai sapere se il problema persiste. Ciao
