Free antivirus for Windows by Avira – Made in Germany
Browsing the internet puts your privacy at risk. Companies want to track your behavior to create a detailed profile about you to serve personalized ads. Browser trackers enable companies to collect a significant amount of data and track your online activities. You can easily become a victim of adware, which is not only intrusive but also slows down your device.
The security of your devices is also at risk, especially when shopping online or using cloud-based services. Cybercriminals are on the lookout for personal data, trying to steal passwords, bank details, or even hijack your computer access to use your devices for attacks against others. Keyloggers, rootkits, spyware, Trojans, and worms are just some of the malware types that can attack your system. To keep your system secure and protect your privacy, you need to install an antivirus software, designed to detect and remove malware. With regular virus scans, you can protect your computer against a wide range of threats.
The Windows Defender Antivirus is installed by default on all devices running Windows 10. While it is a good option for conducting basic virus scans, it does not offer complete protection. When tested by IT security experts, the default windows antivirus didn’t perform as well as other antivirus software, often failing to block malware. Furthermore, Windows Defender is not updated often enough to keep up with the new threats. To detect the new types of malware that are being spread daily, cybersecurity experts recommend an additional antivirus to conduct real-time virus scans and alert you as soon as a malicious threat is detected.
