I was on my 'test box' pc (no security installed) and IE6 started popping up with adverts for some registry cleaner app called "Reg Helper". I closed it and it automatically started IE6 up again asking if I was sure I didn't want to download Reg Helper. Then when I closed that it left some gray box pop up ads for it.
Is this program a trusted registry cleaner app? I would not trust any software with an advertising campaign like that.
I was on filehippo.com at the time.
