Opensource ZIPs flagged as virus

[sbgtrading]

I've been exporting indicators out of my NT 7 beta 14 platform, just opensource (not compiled)...and it works fine except when I go to email that zip file using Yahoo. Yahoo refuses to let me attach the zip file because is says there is an "uncleanable virus" in the attachment.

For one, I don't believe I have a virus on my computer...but even if I did, is it possible to have the ZIP infected by it?

If I don't have a virus that can infect the zips...then perhaps Yahoo is finding something in the document that it considers malicious. Any guess what that may be?

I've attached the most recent example zip to this post.

Thanks,
Ben

Unfortunately I would not know as the ZibLib which we're using is a well known 3rd part component: http://www.icsharpcode.net/OpenSource/SharpZipLib/

...I failed to mention that all opensource zips coming out of NT 6.5.1000.15 are not a problem in Yahoo...and never have been.

This is what has me really perplexed.

Could be the case. ZipLib coming with NT7 is up to data and a different version than the one with NT6.5
