I used "IObit Uninstaller" and it worked, surprisingly. I went into the registry myself and deleted the remaining data left over.
What IS Security update #KB316?
I know it's not a real update, but it also doesn't seem to have done ANY damage to my computer.
I really want to know what it is...in case it comes back.
Also, what's the best way to clean my computer of registry errors and viruses for free?
Is "CCleaner" good for cleaning my registry?
Thanks for your help!
