AirReview is owned by RankBreeze, who produce a suite of property management products. They publish updates regularly, and their products, including AirReview, are made available via the Chrome Web Store and the Mozilla Firefox Browser Add-On portal. Those stores will typically remove extensions if they are rumored to have any kind of viruses or malware.
Of course, nothing is ever fail-safe, and you should only install software if you feel comfortable and safe doing so.
However, if you ever want to explore this further, RankBreeze has a website and offers support for AirReview for any issues of concern.
