Lukas Pelser from Sophos discusses the complex relationship users have with antivirus software, often seen as necessary but criticized as bloatware due to frequent notifications. The legacy of John McAfee influences public perception of antivirus solutions. While some believe digital safety relies on common sense, this approach is inadequate in corporate environments where security practices may be lax. Antivirus software has evolved since the 1970s from detecting known malware to struggling against sophisticated cybercriminal tactics. This evolution highlights the need for businesses to update their cybersecurity strategies to address shifting threats effectively.
