Il log è a posto.
Emsisoft Anti-Malware lo hai acquistato o hai la vs di prova ? se è in prova rimuovilo non serve.
Vediamo se c'è della spazzatura nel pc, fai queste scansioni:

Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/2-adwcleaner
Chiudi tutti i browser (è importante IE,Firefox Chrome ecc...)
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 con le eliminazioni.
Postalo qui.

Scarica Junkware Removal Tool sul desktop.
http://www.majorgeeks.com/mg/get/junkware_removal_tool,1.html
Disattiva temporaneamente l'antivirus per evitare potenziali conflitti.
Doppio click su JRT
Lo strumento si aprirà e avvierà la scansione del sistema.
Devi avere pazienza in quanto questo tool può richiedere del tempo per completare la scansione .
Al termine, un log (JRT.txt) viene salvato sul desktop e si aprirà automaticamente.
Postalo qui.
Ciao

Non è stato trovato niente il pc sembra a posto, non hai risposto alla mia domanda su emsisoft.
