Removing Win32 Bagle.HE Worm
Alke Stilwell
You do not have to disable or remove your antivirus program when you install the MSRT. However, if prevalent, malicious software has infected your computer, the antivirus program may detect this malicious software and may prevent the removal tool from removing it when the removal tool runs. In this case, you can use your antivirus program to remove the malicious software.
Because the MSRT does not contain a virus or a worm, the removal tool alone should not trigger your antivirus program. However, if malicious software infected the computer before you installed an up-to-date antivirus program, your antivirus program may not detect this malicious software until the tool tries to remove it.
Unlike most viruses, worms do not usually modify or "infect" existing files on a computer. They are usually self-containedfiles, often dropped into system folders such as the Windows folder. Therefore, removing a worm from a computer should simplybe a matter of identifying and deleting the files it installed, and the registry links that may be pointing to them. However,removal may be made more complicated because:
Virus scanners are good at detecting and removing the files belonging to worms, but they often do not repair or remove theregistry changes correctly. Therefore an anti-virus program can sometimes do more harm than the worm, by removing it andleaving the computer unusable, or displaying various error messages when you use it.
