DO NOT INSTALL PERFECT UNINSTALLER or EASY DUPLICATE FILE FINDER THEY ARE SERIOUS MALWARE. The crook doing this has taken care to name them almost exactly the same as genuine software. You need to be careful.
The site and software that it links to is actually part of a laughably elaborate set of web pages with meaningless awards that link to nothing and like I said, it's got the same name, with a hyphen or two added, as real software. It's very, very bad malware. They even had it on Download.com where I'll be going next to inform them. He runs a network of malware under the group name CheeseSoft or QiWang Computer selling rogue software and is out in China I believe, when I looked on Whois. Just google them but ONLY take notice of legitimate sites. You'll soon see the only person who talks about his products is, um, him. Here's a link to someone else who found out what he was up to. http://blog.emsisoft.com/tag/qiwang-computer/. Oh and Wilderssecurity are on to him and they know their stuff on there. http://www.wilderssecurity.com/showthread.php?t=*******
What legit software installs something like this in your windows directory and what the hell is a. LIE file;-) http://i.imgur.com/TcHeuRm.jpg
Hope that saves some members from a messy computer.
Also been informed that another rogue site of theirs is http://www.acautilities.com/award.php - so funny look at ALL THOSE AWARDS that link to nothing and, um, they just pretended to get.
EDIT: And, just to prove my point, they have now changed the name of the software from easyduplicatefilefinder to easyduplicate finder. Guys, you can run but you can't hide. I'm not about to let up on this any time soon.
