How to Fix a Window XP Virus Infected Computer

1. Perform a Windows update to ensure your system is equipped with the latest high-priority settings. Updating your system files patches vulnerable data and system resources, helping you keep your existing data more secured. Click the 'Start' menu, followed by 'Programs' and launch 'Windows Update.' Note that an active Internet connection is necessary to update your Windows XP computer.
2. Obtain a respected antivirus tool. Commonly used applications include Microsoft Security Essentials, AVG Free, Avira Antivir as well as Avast! Free Antivirus. Such programs are free and offer consistent version upgrades to ensure maximum computer security. Install them to their default directory and restart your computer if prompted to do so.
3. Update your antivirus program with the most recent virus definition files. Launch your antivirus tool and select the 'Update' option from the application's main menu. An antivirus' definition files inform the software of the latest computer threats to remove them effectively from your Windows XP computer.
4. Restart your computer and press 'F8' before your Windows XP logo is displayed. Select 'Safe Mode' from the Windows Advanced Options menu. Safe Mode allows for optimum computer maintenance because only core system files are loaded, preventing potentially malicious code from initializing and causing further damage.
5. Launch your antivirus program from its desktop shortcut or from the system tray icon. Perform a full scan from the program's menu. Allow it to inspect every file, drive partition and physical hard disk available, because the virus could potentially spread among equipment without the user's knowledge. When finished, the antivirus tool will remove all threats automatically. Otherwise, select the list of viruses detected and remove them from the program's given menu options.
6. Install a secondary antivirus program if you suspect your Windows XP computer might still be infected. Antivirus tools may not immediately detect the latest computer viruses even with the latest definition files installed, especially if the virus in question is particularly new.
