ciao ,
il tuo log è pulito

prova a fare uno scan online Kaspersky o bitDefender
http://steven.altervista.org/files/scan.html

Credo si tratti di questo:
Il BHO.LinkOptimizer.E è collegato al Trojan.Win32.Rootkit.E. Questo malware visualizza popup di pubblicità in base alla parola ricercati con i motori di ricerca Google.


Nel computer infetto inserisce nelle pagine web visitate dei link riferite a certe parole chiavi come: virus,spyware, security, etc. Il link fa riferimento al sito slowl.com, il quale re-indirizza ad altri siti come: search.ebay.it, www.findstuff.com,

rpicamps.com, robogold.biz, www.camouflageclothingonline.net.

Ma non so come toglierlo.
