Similar to other threads I've read, I've believe I've got the HTTP LOP Toolbar Activity/LOP advertising Trojan. I have the Norton intrusion blocker constantly popping up and my PC is terribly slow/some applications won't start. I've run some recommended anti-spyware/anti-trojan programmes to not much avail before finding this excellent forum. I have now run HJT and attach the log. I did look at other posts, but wasn't confident about trying some initial fixes from the log unsupervised. Your help would be much appreciated.
