Hi All, newbie user - windowsXP, 4.18.8, cable

Trying to open files (all five star quality) using winRAR - every time I get a message saying the file contains trojan horses or adware - and the unzip operation comes back with the following:

Cannot execute "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\Rar$EX00.593\S etup.exe"

I have tried the same title 20 times but always get this message.

Hope somebody can help

Best Regards
