Choosing an antivirus starts with understanding the risks. Windows PCs and Android devices are common targets because they are widely used, which makes them attractive to attackers.
Modern threats include malware, ransomware, spyware, phishing, keyloggers, adware, rootkits, and malicious Android apps disguised as legitimate tools. Some threats steal passwords or personal data, while others lock files, monitor activity, or give attackers hidden access to your device. What makes today's environment more challenging is that attacks are more sophisticated than before, with AI-assisted tactics, zero-day exploits, and highly convincing phishing attempts. Strong antivirus protection is designed not only to catch known threats, but also to respond to suspicious behavior before damage is done.
