How to Check Your Computer Without Antivirus Software

Antivirus software is a crucial layer of protection, but there are times when you might need to check your computer without it. Whether it's due to conflicting software or simply wanting a second opinion, here are some methods to examine your system.

Use Built-in Windows Tools

Windows offers several built-in tools that can help you check your computer. These tools are reliable and usually sufficient for basic diagnostics.

• Windows Defender: Even if you don't have a third-party antivirus, Windows Defender is built into Windows 10 and 11. Run a full scan to check for potential threats.
• Task Manager: Press Ctrl + Shift + Esc to open Task Manager. Look for unfamiliar processes using a lot of system resources. Right-click and search online to verify their legitimacy.
• System Configuration (msconfig): Use Msconfig to check startup programs. Disable anything unfamiliar or unnecessary to ensure it’s not malware.

Use Online Virus Scanners

Several reputable online scanners can examine your files for viruses. Here are some popular options:

• VirusTotal: Upload individual files to check for viruses. This tool uses multiple antivirus engines for a thorough scan.
• Norton Power Eraser: Download and run this tool if you suspect your PC is infected. It aggressively targets threats.
• ESET Online Scanner: This free tool scans and cleans your system without installing software.

Use System Clean-Up Tools

Cleaning up your system can sometimes rid it of unwanted software and potential malware. Tools like CCleaner can be useful:

• CCleaner: Run CCleaner to delete temporary files and clean the registry. It also has a built-in tool for managing startup programs.
• AdwCleaner: This tool is excellent for removing adware and potentially unwanted programs (PUPs).

Boot into Safe Mode

Safe Mode loads only essential drivers and services, making it easier to detect and remove malware. Follow these steps:

1. Restart your computer and press F8 before Windows loads.
2. Select Safe Mode with Networking to access the internet if needed.
3. Run scans with any of the tools mentioned above while in Safe Mode.

Keep Software Updated

Ensure your operating system, browsers, and all software are up-to-date. Security patches are released regularly to fix vulnerabilities that could be exploited by malware.

Conclusion

While antivirus software is the best defence, these methods can help you check your computer if you're without it. Always be cautious when downloading files or clicking on links, and regularly back up important data.
