Small mistake at website

I noticed really small mistake at Download Antivirus for Mac | Free Antivirus Software for Mac
In File Details it says that the size of CIS installer x86 is 48 MB (50,179,528 bytes). But really it is 30,7 MB(32 206 280 bytes). Also with x64 it says the size is 50 MB (51,955,656 bytes), really it is 32,6 MB(34 286 024 bytes).

This might explain why the mistake, most likely to fixed soon.
