I have uninstalled Internet Download Manager from my Computer running on windows 7. But still in registry search it show about 70 entries that could not be yet removed. How can I clean it?
If you are sure that you have found the correct keys, you may just delete them from the registry after creating a backup.
However, my personal advice is: do not touch your registry unless you really know what you are doing. Assuming from your post, this is not the case. Therefore just leave it as it is, it should not cause any problems. Also, do not install crapware as the "Internet Download Manager" if you want your system to function properly.
