I registered a Credit card Number, nothing more, i don,t agree to pay for Avast services. But Avast deducted my Credit Card money. The truth is, I don,t need Avast services! During the Trial, Avast free to delete my PCs EXE file(Lantern.exe), without any warning! I have completely lost confidence in Avast and decided not to use your services, please immediately return my money!
You want a refund just because 1 file was deleted because you had set avast to do so ?
That is nuts.
Yes you agreed to take a paid subscription if you didn’t ended the trial in time.
It was clearly stated on your screen.
How to ask for a refund has been explained over and over again on this webboard.

I download lantern.exe from GitHub. Event this file is suspicious, Avast has no right to delete my files directly(every setting on Avast are Defualt).
I think this software(Lantern) is safe, so why Avast delete a non-virus file directly?
I am not too concerned about what I set up in Avast, perhaps because of this reason Avast directly buckle my Credit Card money? Anyway, I will no longer use any version of Avast.
Why not you report this file to avast viruslab for FP and they will check it farther.
