HTTP: Multiple AV Vendor Invalid Archive Checksum Bypass1
This signature detects attempts against a known vulnerability in the way multiple anti-virus products scan ZIP archive files. A malicious ZIP archive containing known trojans or viruses may be downloaded and stored on the local file system without the affected product raising a warning or otherwise informing the user of a potential threat. The product in such a case exhibits ineffective and misleading behavior.
