RAR files are compressed files that must be extracted to your hard drive. The setup will be in the extracted files. WinRAR will extract it, but a good, free alternative is 7-zip. www.7-zip.org

Yeah, what everybody said.

Now go get 'Avast'. a freeware antivirus program that kicks it: http://www.avast.com/eng/avast_4_home.ht...
I recommend you downloading the free version of AVG...

You need a program to open .rar files just like winzip opens .zip files.

The program you will is Winrar just try that, but it does seem to have alot of dots in the file name. Is that the proper file?

Anyway hope that helped
1) Downloading on p2p is a very bad idea - you have no idea what you're really getting (or from whom you're getting it).

2) To open an .rar file, you need 7zip. Download it from it's site, not on p2p - http://www.7-zip.org/
