A browser hijacker like Thunderanvil and Rouduranter may not directly cause as much harm as some other forms of malware, however, it is not entirely safe. The potential for unwanted changes, compromised privacy, exposure to malicious content, and other security risks associated with browser hijackers underscores the importance of adopting strong cybersecurity practices. Regularly updating your browser software, installing reputable security solutions, being cautious with downloads and extensions, and promptly addressing any suspicious browser behavior are essential steps in preventing the encounter with potential hazards posed by browser hijackers.
