Avira segnala Heur-Dblext crypted!

[Wildman]

Salve, da circa una settimana Avira mi segnala questo file infetto, per la precisione è un file dat.exe della cartella temp.
Ho cercato informazioni sul sito ma è piuttosto vago, e cmq non riesco ad eliminarlo, mi aiutate?
Il pc è un vaio VGN- con windows XP abbastanza aggiornato, per la cronaca internet explorer non funziona, appeno lo apro si blocca.

Ciao e grazie

[c.m.g]

fixa questi:

O15 - Trusted Zone: *.whataboutadog.com
O15 - Trusted Zone: *.whataboutarabit.com

fai una passata con ccleaner e cambia browser a favore di più sicuri come opera o firefox con relativi plungin di sicurezza.

[Bugs Bunny]

posta anche un log di findawf, per sicurezza

[Wildman]

Eccomi di nuovo, posto il log di awf, con ccleaner non mi sembra di aver trovato qualcosa di strano.
