I was hacked on Runescape and need advise :)?

Ok... so today i say a guy saying giving away 32m... i never fall for the scams btw. and there are like a lot of people following the guy including me. we go to Juliet house from the quest with romeo and Juliet. there was a lvl 50 guy there that said let me see your claws in trade, so i opened trade and showed him... he started pressing accept and i quickly pressed decline. The weird part was tht wen i pressed decline, my mouse went right on to the accept button... anyways i had my claws and he asked again if he could see them. this time i said no to him. then he yelled "hahahahahahahahhaaa" and said GF fighters torso and claws..... he logged out and i was like ok um wtf. then suddenly my comp crashed and in couple mins i logged back on. CLUE 1: it said last logged in from: (and some random numbers). CLUE 2: i ended up in the varrack bank with no fighters torso and no dragon claws....meaning they dropped the torso(fml hah) and stole claws...... Im not that good at runescape....i played for more then 8 years now, made 19m and my claws were my bank :( GF BANK. Please if you can give me any advise... Once again, i am not asking for your money but if you would like to help out that would be very appreciated. My username is Arty w5 . Advise... thank you. :)
