Is Adaware AdBlock safe?

Low risk

Adaware AdBlock posts telemetry when it is installed or updated and then on a daily interval. The payload includes a persistent install ID, install date, campaign/source fields, and browser, platform, extension, and locale details.

Shared hosts - 7 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
