Update
The Comodo Instant Malware Analysis online tool says that QTTask.exe is classified as Suspicious+.
SHA1 is always the same
(SHA1: <234f24bdb1bf04e9c38da19c4b628c5a344d8660>)
The shown alert is the same I had in my Comodo Defense+ log.
So, could you please verify this situation?
Thank you for your support.
Update 2
After having uninstalled QuickTime form my pc, Defense+ does not alert anymore.
I'm sure it's a false positive. So, please, fix the problem if possible.
Thank you for your support.
