Grazie per l'attenzione!....

Ho provato a fare quello che mi hai detto: anche virustotal mi dice che non sono file infetti...

Mi sa che questi non sono dei virus, anche se non ho la più pallida idea di cos'altro possano essere!...O comunque gli antivirus non me li rilevano in nessun modo..

Non vanno via nemmeno in modalità provvisoria!

I loro nomi sono generici e non mi dicono niente, se ti può aiutare sono questi:
- QUu
- RT
- e in più ce n'è uno che cambia continuamente nome: ora si chiama mMsK!!

???????????????

Niente da fare nemmeno così... sono sempre lì porcocane!

Spero ti sia utile, ma l'avevo già inserito in precedenza...
Comunque eccolo:

Niente... non se ne vanno..

Mi sa che mi tocca riformattare tutto... (al limite ti potrei postare le immagini delle finestre di dialogo di questi files, se ti potesse servire a qualcosa...)

P.S.: è la seconda volta che mi capita che mentre scrivo la risposta su questo forum improvvisamente mi si chiude Explorer...
Sarà un problema collegato? Possibile qualche controllo dall'esterno?
