Some users have reported that Kaspersky Anti-Virus is detecting the Trojan program "Packed.Win32.Krap.ao" in the Zim file ztc.dll. Be advised that this appears to be a false detection and we are working to resolve this for the next build of 8.20. We have scanned this file with 19 different programs and Kaspersky is the only one presenting this detection. If you have encountered this problem, please add an exception for the file ztc.dll until we are able to provide a new release which resolves this issue.
