How to Detect Malware on Your Device
Detecting malware involves using a combination of software tools and manual techniques. Here are some effective methods:
1. Use Antivirus Software
Antivirus software is a primary tool for detecting and removing malware. It scans your system for known threats and provides real-time protection. Popular antivirus programs include:
