How to Remove Runonce in Regedit

Runonce computer worm slows the computer.

Runonce, also known as I-Worm.Runonce, is a computer worm that spreads through malicious email attachments. Once installed on your computer, Runonce locates your email contacts and sends itself to these contacts. Additionally, Runonce places a registry entry in the system registry. This registry entry allows the computer worm to run every time you turn on the computer. Note that the removal steps described apply to the Windows Vista and 7 operating systems.

Instructions

1. Log in to the Windows operating system using the administrator name and password.

2. Click the "Start" menu located in the Taskbar, type "regedit" into the "Search" box and press "Enter." The Registry Editor opens.

3. Right-click "HKEY_LOCAL_MACHINE\Software\I-Worm.Runonce" in the left pane of the Registry Editor and select "Delete" from the menu that appears.

4. Close the Registry Editor and restart the computer.

Tips & Warnings

• Microsoft creates and places several RunOnce registry keys in the system registry. These registry keys are necessary to run programs on the computer and should not be removed. They include:

• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
