What should I do if my PC has a virus?

If a user suspects that their personal computer has been infected with a virus, there are several essential steps to follow to address the issue. First, the user should disconnect the computer from the internet to prevent the virus from spreading or communicating with external servers. This includes disabling Wi-Fi and unplugging any Ethernet cables. Next, running a reputable antivirus or anti-malware program is crucial. Many of these programs provide on-demand scanning or real-time protection that can detect and eliminate malware. If the computer does not have an antivirus installed, it would be wise to download one from a trusted source using another device. After running a full system scan, the users should follow the prompts provided by the antivirus software to remove any detected threats. Additionally, users may want to consider booting their computer in safe mode, which restricts non-essential programs and can make it easier to remove stubborn malware. It is also advisable to update the operating system and installed software regularly to patch any security vulnerabilities that may have been exploited by the virus. Lastly, if the virus removal process does not fully resolve issues or if the computer's performance remains sluggish, seeking professional technical assistance may be necessary. For further guidance, it may be helpful to check current online resources related to troubleshooting computer viruses, as they can provide updated information and strategies.
