Salve a tutti. Da un pò di tempo, circa un mese, ho registrato sul mio pc un rallentamento progressivo, soprattutto durante la navigazione internet e la lettura di documenti .pdf che consulto spesso per lavoro e studio. Ma il segnale più allarmante è la frequente comparsa, durante la chiusura del computer, di alcuni messaggi relativi ad operazioni ancora in corso dal nome un pò sospetto. Tra queste in particolare WidgiBho, S3timer.exe e altre qualificate con indecifrabili caratteri nipponici...
Ho Windows XP, SP2. Come sistemi di protezione attivi, ho avast antivirus, sygate firewall, spybotS&D, e di recente ho installato un programmino, TrojanKiller, che alla prima scansione, qualche giorno fa, ha individuato e rimosso diverse componenti sospette. Devo anzi dire che dopo questa scansione, alcuni messaggi di chiusura sembrano essersi diradati, soprattutto quelli relativi a WidgiBho, ma permane il rallentamento generale (soprattutto quando tengo aperti ebook in pdf, sembra che stia scaricando un reggimento di fanteria) e saltuariamente compaiono in chiusura messaggi di operazione in corso dagli improponibili nomi in giapponese (o cinese?)
Ho effettuato poco fa una scansione con HijackThis, e se non vi dispiace posterei il log così che possiate darmi qualche suggerimento sul da farsi. Vi ringrazio da subito.
