Here is a step-by-step guide to effectively remove malware or unauthorized activity from your computer, regardless of whether it is running Windows or Linux: 

1) Disconnect from the Network: As soon as you suspect malware or unauthorized activity, disconnect the affected computer from the network to prevent further damage or data theft. In this case, disconnect the computer from the internet. 

2) Identify the Malware Symptoms: Look out for any unusual behavior such as slow performance, unexpected pop-ups, strange network activity, or unauthorized changes to files. 

3) Utilize Antivirus Software: Run a comprehensive system scan using reputable antivirus or anti-malware software. Make sure that your antivirus definitions are up to date. Allow the software to quarantine or remove any identified threats. 

4) Boot into Safe Mode: For Windows systems, boot into Safe Mode to prevent malware from loading during startup. This can make it easier to detect and remove malware. You can access the Boot into Safe Mode option from the settings tab on your computer. 

5) Manual Removal: If the antivirus software fails to completely remove the malware, you may need to manually remove it. Identify any suspicious processes, files, or registry entries and carefully remove them. Exercise caution when modifying system files, as deleting the wrong files can lead to system instability. 

6) Restore from Backup: If the system is severely compromised and you have backups of your data, consider restoring the system from a clean backup. Ensure that the backup is from a time before the malware infection occurred. 

7) Update Operating System and Software: Keel your operating system and all installed software up to date with the latest security patches. Malware often takes advantage of vulnerabilities in outdated software. 

8) Monitor System Activity: After removing the malware, closely monitor the system for any unusual activity or signs of reinfection. Keep your antivirus software active and regularly scan your system. 

9) Educate Users: Educate yourself and fellow users on safe computing practices, like steering clear of suspicious links and email attachments, and exercising caution when downloading software online. 

10) Seek Expert Assistance: If you cannot eliminate the malware independently or if your system is crucial to your operations, think about reaching out to a professional IT security specialist or consulting a cybersecurity company. 

Keep in mind that stopping malware before it happens is important. Make sure to update your system and software often, create strong passwords, and follow security guidelines to reduce the chances of future cyber attacks.
