Exam SY0-501 topic 1 question 632 discussion

why is there no dispute on this question? or am I the only one doubting if the answer given is correct?

After a bit of thinking + researching I came to conclusion that yes, the only option is B. Crypto malware is mining/encrypting files., but antivirus is giving notifications, because malware might be relatively new (was zero day until AV update) or something like that. This is really all I could think of.

Answer is root kit because cryotomalwe encrypt and lock files here is the sign of rootkits Top 5 Signs of Root kit Virus Infection: Blue Screen of Death – If you are experiencing Windows Error Messages on Blue Screens with White Text and are having to constantly reboot, then there is a possibility of the symptoms of Root kit virus. Dramatically Slow Performance – Is your computer running painfully slow even though you have nothing open? Constant memory drainage can be another sign of an infection. Web Browser Redirects – Unusual web browser behavior such as Google link redirection or unrecognized bookmarks can be something else to check for when searching for a Root kit virus. Anti-virus disabled – If you find that your anti-virus has turned itself off leaving your PC unprotected then this another indication of the Root kit Virus. Incorrect PC clock & date – If after replacing your computer’s CMOS battery you find that your PC clock and date are constantly changing then this could be a further sign of the Root kit Virus at work.

Crypto-malware • New generation of ransomware • Your data is unavailable until you provide cash • Malware encrypts your data files • Pictures, documents, music, movies, etc. • Your OS remains available • They want you running, but not working • You must pay the bad guys to obtain the decryption key • Untraceable payment system • An unfortunate use of public-key cryptography

actually the key here is " ✑ Pop-up messages in the task bar stating that antivirus is out-of-date " so they assume if there no definitions up to date .. it should be virus

Ransomware requires that someone pay the ransom, while crypto-malware can operate indefinitely on a system, benefiting the criminal without the victim having to do anything, and may never be noticed.

"Errors when attempting to open local Word documents and photo files" so we can immediately rule out C and D as the problem isn't just isolated to network connectivity

this is a good case of "all the answers are bad" the only logical explanation to some of the problems is Ransomware.

My answer is C, but I have doubts about this question. I didn't pick B, because Crypto-malware is ransomware that encrypts the user’s data. It might be the option only to the issue of "Errors when attempting to open local Word documents and photo files". It doesn't relate to the rest though. That's a weird question. Any thoughts?

"Pop-up messages in the task bar stating that antivirus is out-of-date" Why crypto-malware? How it is related?
