FAQ
Does PrivacyGuard protect against viruses like Kaspersky?
No. PrivacyGuard is a browser-level privacy tool — it blocks third-party trackers, enforces HTTPS, and removes fingerprinting scripts in the browser. It does not scan files, quarantine malware, or provide system-level antivirus protection. For full system protection, Kaspersky or a comparable AV suite handles the threats PrivacyGuard does not.
Should I use both PrivacyGuard and Kaspersky?
Yes — they protect different attack surfaces. Kaspersky covers your system: file-based malware, phishing email detection, network intrusion. PrivacyGuard covers your browser session: ad trackers, data brokers, fingerprinting, and insecure third-party scripts. Running both is the most complete protection for most users.
Does Kaspersky slow down the browser like some security suites?
Kaspersky's browser-integration components (Safe Money, URL checker) do add measurable overhead. PrivacyGuard is built to be lightweight — blocking is done at the declarative network request level, with no inline script parsing that would add latency to page loads.
