and.....they also offer this advice further down in their spiel....
You do need to read everything, though, because you could end up with more than just the utility you wanted to download and install. In one of the last installation steps you can easily miss the Bing toolbar download option, for example. If you don't want to go through uninstalling/deleting extra programs, then make sure you read and unclick where needed.
Therefore, the PUP here is not Unlocker....it is the crap that has been bundled with it.
Personally, I hate crap that is added in a deceitful manner.....so i would remove it just on principle
You can always reinstall Unlocker (carefully !...custom install !)

It has been said that time heals all wounds. I don't agree. The wounds remain. Time - the mind, protecting its sanity - covers them with some scar tissue and the pain lessens, but it is never gone. Rose Kennedy
