Answer 2

Exactly, I had ransomware virus into my PC and it often popped out ads into my PC that redirected to malicious websites... As you said data corrupted all my important files and stolen my private information. I did not have any kind of windows antivirus in my PC at that time.. Later I realized how important is antivirus to PC and installed them and deleted those viruses. I would suggest each and every PC to have an antivirus to stay secured from viruses.

Answer 3

Most of the time, it just annoying. I'm not talking about those serious ones, i've got adware, browser hijacker and ransomware, drive me crazy already. Since the infection, my PC running speed was decelerated and it got weirder later, as the system resources have been taken by unknown applications/processes running in the BG (triggered by viruses). Have to remove the computer virus completely and timely.

Ransomware is one of the most "popular" malware these days.
Once it's taken over your computer, threatens you with harm, usually by denying you access to your data, which means all the files on your computer would be locked with an encrypted key. The attacker demands a ransom from the victim, promising — not always truthfully — to restore access to the data upon payment.

The victim would be shown instructions for how to pay a fee to get the decryption key. The costs can range from a few hundred dollars to thousands, payable to cybercriminals in Bitcoin mostly.

There are a number of vectors ransomware can take to access a computer. One of the most common delivery systems is phishing spam — attachments that come to the victim in an email, being faked as a file they should trust. Once they're downloaded and opened, they can take over the victim's computer, especially if they have built-in social engineering tools that trick users into allowing administrative access. Some other, more aggressive forms of ransomware, like Dharma Ransomware, exploit security holes to infect computers without needing to trick users.
