Any viruses or worm in that folder is harmless till you decide to roll back and use that particular infected point. Any viruses in that folder is easily remove by just turning off System Restore and viruses are gone.

Hi rpggamergirl,

Previously i scanned my laptop with combofix in normal mode. Now i scanned with combofix in safemode. Virus has been removed from my laptop.

Thank you.
ComboFix was designed to run in normal mode, safe mode is only needed if PC can't boot normally.
Glad to know it's resolved.
When you're done with ComboFix you can uninstall it.

To uninstall Combofix:
Go to Start > Run and 'copy and paste' next command in the field:

ComboFix /Uninstall
