Virus removement by Antivirus software

[JonasArnold]

Panda Security recognizes DECRYPTION as a virus and removes it irreversible!
I guess the problem is, that the software is located directly on the C:/ drive...
Therefore I may change the install-location to %programfiles% or so.

Install directory moved to %programfiles% in commit f74da24.
Didn't test yet if Panda Security does still remove it.

AV programs work by analyzing files for patterns of known "bad behaviour" and by analyzing potential malicious files in the cloud.

If your program is dereferencing pointers, writing 200 bytes into a 100 byte buffer or similar, chances are you will generate code that is similar to a signature of a known attack.
(since most attacks exploit these kinds of programming errors)

You should debug your code and make sure that memory is handled correctly. In addition to that, I highly suggest you to upload the file(s) to the VirusTotal website, which checks the uploaded files against more than 40 Anti Virus solutions. With a green light from this site, you can safely add the executable and other affected files to the exception list of your Anti Virus program (in your case Panda Security).
In case you don't know how, visit the website of Panda Security.
