I tried their uninstaller, and creating a read only file named nail.exe, neither worked.:(
A little further searching on the internet and I found ewido security suite, it did the trick to get this Aurora crap off my pc without having to reinstall windows.
Of course not...Interesting that the only way you can remove it is by using their Tuneup tool...hmmm...my computer was perfectly tuned prior to this crap...seems like thier tuneup software doesn't do what it says...sounds like false advertising to me
