Has anyone scanned the latest build with their anti-virus software? I've noticed with build 299, I get a "not an archive" message (I'm using ESET SS version 3 and version 4). Never had this occur prior to build 299. I downloaded the update on both an XP and Vista box (for scanning purposes), and both produced the same message. No viruses or other indications, but made me curious if anyone else has scanned 299.
