I use Secunia PSI to warn me when software on my Dell Inspiron 6400 (Windows XP Home) needs updating. The program is telling me that my Intel PRO/Wireless 3945ABG Network Connection Software 10.x is insecure and needs to be updated.

I went to the Intel site and downloaded the updated software (version 12.1.2.0). Now, this may seem a dumb question… but I’m not sure what to do next! The download came in a zipped folder which I unzipped, and I presume that I have to double click on one of the files, but which one? There are 2 sys files and 2 exe files. I’m scared that if I click on the wrong one that I’ll wreck something. Can some kind guy explain the correct process I need to follow to update this?

Thanks
