Virus encrypt infection from an Encrypted email file
I have an email client that downloads all my emails, the recently I received an email with a key encryption tha I had to enter in-oder to read. Later the computer started to respond slowly and I suspected it to be a malware, is it possible to get a malware in an encrypted file? if so how can the anti-virus scan for encrypted files without the key for decription? How can I safegurad myself against threats from such malwares
