Integrity of NOD32 installers

A simple question:
I've checked the integrity of the installers of NOD32 trial versions (Win9x and Win2000/XP) with WinRAR (version 3.30) and 7-Zip (version 4.20) and both report that the installers are corrupt. WinRAR shows the following message (translated from Spanish):
"The authenticity information is not valid or is damaged"
"The header of file "" is damaged"
I've downloaded both installers from multiple locations (NOD32 Argentina, NOD32 Uruguay, NOD32 Latin America) and I always get the same message. However, both install fine with zero errors.
Checksums (MD5):
- ne98spst.exe (2.70.39): 5674feb9ff940d79f88830bd2010823b
- nentspst.exe (2.70.39): 37dd74f975bdcb9ec1e41eb74f9cfcd7
Is this a normal/expected behaviour? Is this a bug in those (old) versions of WinRAR and 7-Zip?
Thanks

 

I get the same errors with WinRAR 3.70 but the files extract fine.

 

Thanks WSFuser. So, it seems that it's a normal behaviour of WinRAR.

 

This is absolutely normal and was confirmed by Marcos some time ago ( I can't find it right now) . WinRAR has problems when dealing with digitally signed stuff , AFAIK.

 

Thanks HiTech_boy. I found this post by Marcos confirming your statement

 

That is what I meant

 

A FAQ entry should be added regarding this topic. What do you think?

 

WinRAR always reports the file as damaged because it doesn't support the "extra information" provided. Basically it's to ensure that Windows (2000) & Vista gets the extra information it needs - Believe me I've asked the same question once since I was baffled why the installer was broke when I used WinRAR. It's perfectly normal and shouldn't be any concern.

 

Thanks to all
