Unfortunately my computer was banned for the use of 'Third Party Software' which has led me to this sad decision that I'm now taking to retrieve my account. Within my household we share the same computer as I currently don't work, my younger siblings are obviously too young to work, my older brother is currently studying, therefore my parents are the main supporters of us, making it very restricting on these said luxuries, however we do get by. With that computer comes my older brother's WoW account which whilst not studying he does play rather hardcore and I have mine, therefore no account sharing has taken place.I was raiding several days back and on a ten minute break decided to quickly run to the shop as some supplies for the night where very needed. Obviously, during this process my computer was left on as I've never had any issues with account breaching from within my house and I never ALLOWED any access to my account. When I returned, I came back to a permanent ban which was extremely crushing and confusing as this was the first ever ban allocated to this account and I purely done nothing wrong. I thought maybe the hacking of my account occurred, therefore ran several virus scans to discover RAT software on the computer which was in turn eradicated from the computer. I done the relevant safety checks, ensuring the safety of my email account and other vital passwords and precoded to format Windows to ensure one hundred percent safety.Throughout that evening I spoke with my brother and due to his heavy workload he revealed that he was using a bot to aid his account which was ran when I was at school (Which is possible due to us having alternative educational timetables). I have minor knowledge about these programs, let alone their background processes and it was being ran in the background consistently. My brother claimed that it was impossible to find after me getting banned, however I was permanently banned for no reason what so ever and I want this to be understood and reverted.After some extensive research I understood how the WoW client works, tracking these sorts of programs and came to conclude that it was a walking time bomb waiting to detonate as one day it would have picked the program up and reported it to Blizzard. Of course that program has been deleted but so has access to my account and for what? My brother's actions? Possibly being hacked? I need some serious help in this matter as this account is vital to me and to lose it for this would simply crush a boy who has been inspired to become one of the best players, however this has tarnished that.
