In the last week or so there has been 3 attempts by different accounts to try to infect me with trading requests, but right away i knew something was up as i have traded many times with people i know and there is no need to post a link to a .jpg picture of the items they are wanting to trade, which will take you to an external link outside of steam to a image.scr file which is not a picture and dont be fooled by the preview image on it, dont download it even though its harmless unless you execute it.
I have been told of 2 people who i know have been infected and when i get to talk to them personally im going to give them a little dig for not knowing better.
Today's attempt, it seems like its a bot, i just watched it do its thing without even attempting to type back.
