It has come to our attention that some of our Rack Extensions users, had issues with their Anti-Virus software (mostly Norton AV users) that reported their downloaded Windows DLL files as potential (suspicious) virus threats. This issue applies for Rack Extensions by other ventors too.
On our side we guarantee that no malicious code exists in our products. Propellerhead software, who also have knowledge of this issue, have also responded negatively to the posibility of something going on in their servers. This means that you may rest be assured that such "suspicious" Rack Extensions are a false positive.
The issue has to do with the fact that some AV programs use "heruistic" protection to scan for viruses. Heruistic protection checks for virus "signatures" that may prove the existence of a potential threat. However some files, might have structures of data that look like a virus "signature" without being themselves, or activate viruses.
What can you do?
For the moment and until there's a permanent way to resolve this situation, you can report the "suspicious" Rack Extensions as false positives. Most AV applications have this option, along with a way to restore your files if deleted. In "Norton Antivirus" you can select to "Restore & exclude this file" clicking on the same titled button in the warning dialog box.
