    Yah, I would think that both a rootkit and back door wouldn’t affect anything. Just gives a bad guy a way to access your data and/or control your computer and hack into the network. If they work like they are supposed to, the end user would never be the wiser. Spyware, again, is software that is installed on a computing device without the end user’s knowledge to covertly obtain info about them. I’m guessing Crypto-Malware “B” is the correct answer. Although worded pretty lamely, it would encrypt your files/hard-drive which wouldn’t allow Ann to open her files and a pop-up would reveal how she can pay the bad guy to unlock her files/hard-drive.

    I think B coz she is not able to open files -> coz the are encrypted. Slow performance coz it takes lots of cpu power to encrypt stuff. Pop up probably displays the h4x0r’s btc address
    Spyware, rootkit or backdoor supposed to be stealth so no popups

    If the threat came in via an email, in the FRONT END, quite visibly and with user interaction, how on earth can this be construed as a backdoor? No way. A backdoor does not require user interaction, and it is just that, a backdoor. This came via the front door. B-Crypto-malware requires user interaction
