Hi, Michael.
That makes sense. However, one of the applications I use installs jailbreak-related files into the tmp directory temporarily before installing it to my iPhone. Whitelisting the tmp directory would probably not be advisable due to obvious reasons. Also, there isn't really a way to whitelist specific files because the files are downloaded with temporary random names.
Also, I understand the risks that come with a jailbroken device, and I am willing to take the given risk because of the functionality I gain from jailbreaking. Additionally, I am very careful in what I download and run on my device.
So, if there is no way to exclude a "type" of detection, is there some place I can provide feedback to Avast to suggest the addition of this functionality?
