When you visit a website, small files (cookies) are stored on your computer containing information about your browsing preferences. This can improve your browsing experience by enabling websites to remember your preferences.
Since the information in cookies does not change, cookies themselves are not harmful.
They cannot infect a computer with viruses or malware. However, a cyberattack can hijack cookies and jeopardize your privacy by tracking your browsing history.
We recommend deleting cookies frequently — not only after visiting a suspicious website or noticing a drop in browser performance.
Unlike Avira Security for Mac, Avira Security for Windows does not contain the Cookie Cleaner feature. Nevertheless, cookies are cleaned from your computer each time you run a Smart Scan.
Another option is to delete the cookies using the integrated Optimizer feature.
