I have Nod32 on several of my home computers. On one computer, the version is listed as 126.96.36.199. On another, it is listed as 188.8.131.52. When available version is checked on both of these computers, the different versions are verified as most recently available. Can this be correct? The computer checked with 184.108.40.206 is using Vista operating system. The 220.127.116.11 is using Windows 7. Thanks.
