Hi

I am trying to find out if ‘Backdoor.Win32.Prosti.~N5@42653872’ that Comodo keeps finding and quarantining is a real threat, or a false positive?

Comodo states that the file is located in IOBit Security\is360srv.exe. (Comodo reported and quarantined the file on the 12th & 14th Feb and also today)

I have looked for the rejoice.dll file which apparantly should exist if the threat is real, but its not on my PC.

Also, If a file is quarantined, how can the same file keep being active a few days later on?

Can you help please?

Hi Clare,

Can you please post a False Positive report here:

on the Quarantine issue it looks like CIS fails to remove the file, probably fights with IObit.

Just done :slight_smile:

Can you tell me what happens now?

Many thanks!

You posted in the wrong topic.
Create a new topic in that section, don’t reply to an existing topic.
Looks like a moderator fixed it. :slight_smile:

Someone from the AV labs will post in your thread that they’ll investigate if it’s malware.
And they will report back (normally within a few hours/day) if it’s FP or not and if they fixed it in version X of the DB.

Many thanks for letting me know :slight_smile:

I have IO Bit Security and I got exactly the same thing. Comodo said it hadn’t found any threats but put Backdoor Win 32. Prosti in the log and said it had quarantined it but when I looked there was nothing in the quarantine. I had to uninstall the IO Bit hopefully that’s got rid of it
