Lightning_Po Dispute

he told me to say this: * Lightning_Po
* Site's reason for temp banning me was : Trojan
* The temp ban was unwarranted because I did not upload said file with trojan in it. Particular Thread would be posted, but I am completely locked out of the site. I did download something with a trojan to test it, which it did come out dirty, but not at first because I hadn't yet updated my Avast! for that day.
* I do
* I don't know who banned me
* I'm not here to b*tch and complain, I just want to know why I was temp banned, because it is very bad for business.
