This is a guide on how to do system restore in Windows 7. Follow the instructions carefully because this will save your computer from virus and spyware infection.
I did an experiment on my machine with a Windows 7 install. My objective is to get my PC infected with a virus to personally experience how important and effective the System Restore function is.
Self-inflicted PC virus infection procedure:
- Uninstall Eset Nod32 version 4.
- Retain Windows Defender.
- Insert a USB flash drive which is infected by a virus. I used Huelar.exe virus in this test.
- Ran the virus, which, by the way, is so fast in replicating itself in Windows 7.
How Windows 7 System Restore helped?
Part of my plan is not to install an anti-virus software and, instead, use System Restore to delete the virus. The result was awesome. Here's how:
- Click the Windows 7 Orb (Start Menu).
- Right-click 'My Computer' and select 'Properties'.
- At the sidebar, click 'System protection'.
- The 'System Properties' window will appear.
- Click the 'System Restore' button, click 'Next' and then select your desired restore point, preferably with the date and time prior to virus infection.
- There will be on-screen notifications, your system will restart, and after reboot will notify you if it is successfully restored.

- Download and install Eset Nod32.
- Scan your system. The folders and files propagated by the virus will be quarantined and can be deleted later.
- To ensure that your Windows 7 system is totally virus-free, delete System Restore points. Here's how:
- Click the Windows 7 Orb (Start Menu).
- Right-click 'My Computer' and select 'Properties'.
- At the sidebar, click 'System protection'.
- The 'System Properties' window will appear.
- Click 'Configure' and then click 'Delete'.
- Click the Windows 7 Orb (Start Menu).
- Right-click 'My Computer' and select 'Properties'.
- At the sidebar, click 'System protection'.
- The 'System Properties' window will appear.
- This time, click the 'Create' button and then type your desired name for the restore point for easy identification, click 'Create' and wait until it is finished.
- Close and exit.
By the way, if you followed the instructions and something went wrong, don't hesitate to ask for help or advise.
