This top of the range antivirus is not like the others
Because it blocks all webcam-hacking, and stops ransomware before it starts. It protects your PC, home network, and passwords against zero-second threats with smart cloud-based detection. It updates your apps automatically and shreds your data permanently when you say so. That’s why you’ve never seen protection like this before.
NEWKeep spies and snoops off your webcam
Can hackers really hijack your webcam? Yes — until now. Webcam Shield makes anything and anyone get your permission before they can use it so nobody takes a peek unless you say so. You can even disable your camera for good — and enable it again. Go on, do your happy dance — no one’s watching.
NEWKeep hostage-takers off your files
Hackers demand an average of $643 from ransomware victims. Ransomware Shield keeps your most important files from being encrypted and held hostage, and lets only trusted apps alter them in any way.
Update your apps against security gaps
Automatic Software Updater keeps your apps and programs up to date with the very latest safety patches and performance upgrades, so you’re not exposed to hackers finding security holes from out of date versions. Safe and convenient.
No data left behind
Thinking of selling your PC, or maybe lending it to someone? You’d be surprised at how easy it is for others to retrieve your “deleted” files and data. Your Data Shredder makes sure your personal photos, bank statements and other private documents get obliterated — for good.
Look inside Avast Premier
