Warning! Avoid These 2 Antivirus Brands

Avast, a well-known antivirus brand, previously faced privacy concerns for selling users’ browsing data to third parties. Since being acquired by a new parent company, they have taken steps to address the issue. They closed the subsidiary involved in data selling and ceased data sharing entirely, demonstrating efforts toward redemption.

2. Windows Defender:

Microsoft Defender (Windows Defender) is a built-in and free antivirus on Windows laptops, providing an additional layer of security.
