I was exploring CCleaner(new to me), and I thought Windows Defender meant Microsoft Defender(which I used to have), therefore I uninstalled Windows Defender Signatures. I would like to know what will be the effect of doing this, and if I should need to get it back how do I do that. I know it's gone and not in the recycle bin. I do not have a windows XP disk, as the OS came with my Dell 2400 desktop computer. Thanks for your reply in advance, Tom.
