Despite having performed all the procedure, ( Software on USB drive ) I am banned from all servers of Battlefield 4.

Running away is a scam for the price!

Yeah...but let me explain something to you

The cheat wasn't detected...you were probably just being oblivious while cheating and an admin in the server you were playing on probably suspected you of cheating. Hence why you probably got banned. 

Wrong! I was just careful, and I only had to play 20 minutes for a score of 35/ 15 without any complaint from anyone. then the next part, I am banned after 5 seconds of presence.

Look yourself up here: https://www.bf4db.com/ 

You've most likely been caught with very abnormal stats and banned from all community servers via BF4DB. You can still play on official servers however since the cheat is not detected and most likely never will be with Punkbuster.

If you just get a message from every server when you join saying "Kicked by Punkbuster" then you're not banned either and you should try uninstalling Punkbuster completely and then reinstalling it.

You can find info on how to do so here: https://help.ea.com/en-gb/help/battlefield/battlefield-4/battlefield-4-punkbuster-troubleshooting/

dude you got flagged by the anticheat because you were to blatant 

I confess not to be a regular with this kind of software, as said above, I left the basic settings to discover the hack. I took advantage of it for 20 minutes and I didn’t abuse it. How could I be detected in such a short time? 

How do you use it?

An admin on the server you were playing on probably was just randomly spectating players and suspected you of cheating. But you can still play on most official servers!!!

Hi there skyonara! Like you, I was not experienced with using hacks in online gaming; however, through the help of this community combined with my experience playing legit for several years, I can effectively mask my use of these hacks which has enabled me to use the products without any issues.

Perfect Aim community members have written a few good guides for folks like us who were new to the scene when we joined and I have also included some tips that echo a lot of the points made in those guides in my own Battlefield 4 testimonial. I will provide a link to some of these guides that I found to be useful below, I recommend you click the links below and read these guides. They helped me and I am sure they will help you as well! Don't let this hiccup discourage you! Please feel free to message me with any questions or concerns.
