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.

On top of our latest features, we cover essential intelligent threat-detection and real-time protection with such a light touch on your PC, you never even know it’s there.
