Single- and Multi-Device options let you choose the protection that works best for you. “Up to 10 devices” means you can share your security with every one of your devices or everyone closest to you.
Avast Premium Security protects against all online threats, including spoofed websites and ransomware. Complemented by SafeZone technology, it creates an isolated virtual desktop, invisible to any possible attacker, where you can do your online shopping and banking securely.

Changes in Avast 21.1.2444 Build 21.1.5914 Beta:
- Fixed: possible BSOD (blue screen of death) due to problems in identity protection driver (internally catched just once on one machine during a month, will fix it in next BETA)
- Fixed: not responding dialog in case of multiple detections at the same time
Changes in Avast 2021 21.1.2443 Build 21.1.5889 Beta:
- Multi-detection fix: If you stumbled upon more detections at once, we wouldn’t show each one in separate alert window anymore. Alert dialogs will be grouped into one, so there is no pop-up overload. Items are grouped by shield. (This applies to auto-mode, in Ask mode, we still show it one by one)
- New categories and description: Our detections are now grouped in various categories of threats and each alert dialog contains a short description of corresponding category (you can find this in Details section). This will also enable us to continuously turn on PUP (potentially unwanted programs) detections ON by default for our users.
- AlertID: We have placed a small numeric identifier in the footer of the detection dialog, so we can easily search the particular detection in our database and identify it based on the screenshot alone. We are often presented with snapshots from our users but up until now these screens didn’t contain sufficient information.
What was fixed
- not correct information in cyber capture detection dialog
- detections by identity protection on drivers with custom label
- missing focus (on top visibility) for identity protection dialogs
- internet connection satus in firewall details was not always properly displayed
- shell extension (scan in explorer) does not scan all files the link (.lnk) files are pointing to
- detection dialogs and toasters when higher DPI (dots per inch) is used (screen resolution settings)
- incorrect license/subscription details/update shown when there is a change

- UI now opens properly on scan results after an Explorer scan finishes (was not behaving properly with UI minimized)
- Fixed a crash that happened in log viewer when logs were too large
