It's lucky actually that whoever is putting these malware rar archives up is too useless to make them extract and run. It would be so easy to make it extract the exe or an autorun file and autoload the malware hijacking the double click of the rar unpacker to authorise the software installation.. *sigh* not all script kiddies have brains eh?
If I had a link for one of these nasties I could have some fun with it.. like make it work with my own bot installer and then seed working files back.. but I only d/l known working clean things...
Always read the comments for torrents.. and don't touch anything suspicious.
I would suggest after deleting it running some good anti malware (malwarebytes?) and a quick rootkit scan.
