Viruses are a common problem for laptop users. They can cause slow performance, crashes, and even compromise your personal information. While antivirus software is the most effective way to remove viruses, there are ways to remove them manually. In this article, we will show you how to remove virus from laptop windows 7 without antivirus.
Step 1: Enter Safe Mode
The first step is to enter Safe Mode. This will prevent the virus from running in the background and interfering with the removal process. To enter Safe Mode, restart your laptop and press F8 repeatedly until you see the Advanced Boot Options screen. Select Safe Mode with Networking and press Enter.
Step 2: Identify the Virus
The next step is to identify the virus. You can do this by using the Task Manager to see which processes are running on your laptop. Press Ctrl+Shift+Esc to open the Task Manager and look for any suspicious processes. You can also use the System Configuration Utility by typing "msconfig" in the Run box and clicking on the Startup tab.
Step 3: Disable Startup Programs
Once you have identified the virus, you need to disable any startup programs that are associated with it. To do this, go to the System Configuration Utility and uncheck the boxes next to any suspicious programs. Click Apply and then OK to save the changes.
Step 4: Delete Temporary Files
Temporary files can also contribute to virus infections. To remove them, go to the Start menu and type "Disk Cleanup" in the search box. Select the drive that you want to clean up and click OK. Check the boxes next to Temporary Files, Recycle Bin, and Downloaded Program Files. Click OK to start the cleaning process.
Step 5: Run Command Prompt
The Command Prompt can be used to remove viruses from your laptop. To open it, go to the Start menu and type "cmd" in the search box. Right-click on Command Prompt and select Run as Administrator. Type "netstat -ano" to see a list of all active connections on your laptop.
Step 6: Identify Suspicious Connections
Look for any suspicious connections in the list. You can identify them by looking at the IP addresses and port numbers. To terminate a connection, type "taskkill /PID [PID number] /F". Replace [PID number] with the actual process ID number.
Step 7: Remove Registry Entries
Registry entries can also contribute to virus infections. To remove them, go to the Start menu and type "regedit" in the search box. Right-click on Registry Editor and select Run as Administrator. Navigate to the following key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. Look for any suspicious entries and delete them.
Step 8: Remove Malware
If you suspect that your laptop is infected with malware, you can use the Malicious Software Removal Tool. This tool is included with Windows and can be accessed by going to the Start menu and typing "mrt" in the search box. Select the tool and click Next to start the removal process.
Step 9: Perform a System Restore
If all else fails, you can perform a System Restore. This will restore your laptop to a previous state before the virus infection occurred. To do this, go to the Start menu and type "System Restore" in the search box. Select the tool and follow the prompts to restore your laptop.
Conclusion
Removing viruses from your laptop can be a daunting task, but it is possible to do it without antivirus software. By following these steps, you can remove viruses and improve the performance of your laptop. Remember to always be cautious when downloading and installing software, and keep your antivirus software up to date to prevent future infections.
