Ransomware is nasty stuff. This type of malware encrypts files on your PC so that you can’t access them – unless you pay the attacker to unlock the data. In other words, your files are held hostage until you cough up the demanded ransom, unless you’re able to survive the ransomware attack using other means.
The best defencetake other protective measures, too. Modern antivirus software often restrict which apps can change files in folders commonly targeted by ransomware. Microsoft Defender, 1. which is built into Windows, can do this too. (Microsoft changed the name from Windows Defender several years ago, but it’s the same program.) Some antivirus suites also run automatic backups, in case you need to restore your files.
