Understanding Computer Viruses and Why Free Tools Work
A computer virus is a malicious program that replicates and spreads between files or devices, often stealing data or damaging your system. Unlike adware or PUPs (potentially unwanted programs), viruses can alter system files, slow performance, or even lock you out (in ransomware cases).
According to Kaspersky’s cyber threat report, over 560,000 new pieces of malware are detected daily. Fortunately, modern free virus removal tools are powerful enough to handle most infections — if used correctly.
Common virus symptoms include:
- System slowdowns or overheating.
- Sudden loss of storage space.
- Applications crashing or not opening.
- Browser redirects to unknown sites.
- Disabled antivirus or security settings.
Step-by-Step: How to Remove a Computer Virus Using Free Tools
1. Disconnect from the Internet
Before scanning, unplug your Ethernet cable or disable Wi-Fi. Many viruses use active connections to spread or hide.
2. Boot into Safe Mode
Restart your computer, press F8 or Shift + Restart → Troubleshoot → Advanced Options → Startup Settings, then choose Safe Mode with Networking.
3. Run a Full System Scan Using Free Antivirus Tools
