But I’m backing up my files to the cloud.
That’s a good habit. But the problem is that the ransomware-encrypted version of your files gets immediately synced with the cloud too...so unless your backup solution stores historical versions of your files, you’re in trouble.
Avoid becoming the victim of digital extortion
Ransomware is quickly becoming one of the most common — and dangerous — types of malware out there. Avast Free Antivirus protects your devices against havoc-wreaking ransomware so you don’t become the victim of digital extortion.
Like the name suggests, ransomware is the digital equivalent of a hostage situation. Hackers use ransomware to encrypt the personal files on your computer or phone, preventing you from accessing them until you — you guessed it — pay a ransom.
Avast Free Antivirus blocks ransomware before it can get anywhere near your files — let alone encrypt them. And don’t worry about accessing and using all of your files (documents, photos, etc.) as you normally would; ransomware protection works quietly in the background.
