All of our archives go through virus-checks before being placed on site. The possibility of such a thing occuring is close to none.

Remember that many antivirus programs are known to cause false alarms every now and then.
Did you enable advanced heuristics in your current antivirus program? Disable and rescan the archive. This function is used to identify new virii not listed in the program's database, but at the same time heavily increases the ratio of false alerts.
Then, just to make sure, try scanning the archive with a different one, like AVAST.
