Anti-virus 'false positives'
Occasionally anti-virus software identifies legitimate programs as a threat. This is because it looks for a binary sequence that 'looks like' the threat. Sometimes, this is just coincidence that a legitimate program contains exactly the same binary sequence.

You may get the occasional 'false positive' where similar legitimate code is mistaken for a virus, but the major anti-virus programs will agree that it is safe.
When the program is created, a unique number is generated that must match when it runs, if this number is different on your PC, Packing Partner will not run. Occasionally there is a problem matching the number, resulting in a message that Packing Partner is corrupt. If you get this message then click here to reinstall the program. Which should fix any issues.
