Run a System Scan for Viruses and Malware

Running a system scan is a crucial step in troubleshooting any issues you may be experiencing with your operating system.

When your computer is infected with malware or a virus, it can cause your system to slow down, crash, or behave erratically.

By running a system scan, you can identify and remove any malicious software that may be causing these issues.

Most operating systems come with built-in scanning tools, such as Windows Defender for Windows or XProtect for macOS.

These tools can scan your system for malware and viruses, and in some cases, they may even remove the detected threats automatically.

To run a scan, simply open the scanning tool and follow the prompts to start the scan.

In addition to built-in scanning tools, there are also third-party antivirus and malware removal tools available.

These tools may offer more advanced features than the built-in tools, such as real-time scanning, automatic updates, and scheduled scans.

However, they may come at a cost or require a subscription.

It’s important to note that even after running a system scan, your system may not be completely free of malware or viruses.

It’s always a good idea to practice safe browsing habits, such as avoiding suspicious websites and emails, and keeping your operating system and software up-to-date with the latest security patches.

By staying vigilant and taking steps to protect your system, you can help prevent malware and viruses from affecting your operating system in the first place.
