What our analysis found

Avast Online Security & Privacy (BETA), used by 40,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can observe network requests. It comes from a trusted publisher and was last updated in April 2023.

The extension is from Avast, a trusted security publisher with a Google trusted badge. Its permissions are broad but consistent with its declared privacy & security functions (e.g., blocking trackers, scanning for malicious sites). Observed code only communicates with the extension's background via internal messaging; there is no evidence of exfiltration to unauthorized third parties. The data collected (website content, browsing activity) is explicitly disclosed in the Chrome Web Store listing. The ML model's low risk score (0.00) and the third-party risk report's low likelihood rating () further support a benign verdict. The reported critical permissions are necessary for this extension's core functionality.
