Chrome: Il certificato di sicurezza del server è stato revocato!

Salve da stamattina che accedendo a siti web via https e google chrome visualizza il messaggio "Il certificato di sicurezza del server è stato revocato!". Inoltre denoto una maggior lentezza generale rispetto a prima che si manifestasse il sintomo. Ho fatto più scansioni di Malwarebytes dopo averlo aggiornato, ha trovato qualche trojan, eliminato, ma il sintomo è sempre presente.



P.s. lo fa anche con facebook

allego scansione fatta con hijackthis
