what IS this? this icon was recently placed on my desktop. AAAAARRRRGGGGGH!!!! another question: can someone indicate to me how i'm to know that sites i'm told to go to by admin's, moderators, other members are safe? many of them suggest downloading some OTHER (beyond the arsenal of spywareblasters, adware killers, AV's, firewalls, etc., i'm already using) software (e.g. a2, or to go to newdotnet to download some other .exe i know little about). incidentally i went to the newdot site when more dubious stuff was placed on my machine (past the firewall, spywareblaster, high IE security settings, etc.). for over a month now my machine's been plagued by hijacks, trojans, i don't know what else and nothing i do seems to help! maybe someone can suggest something more drastic (like recommendation of a reinstallation of OS etc. or something short of it, prefereably)? thanks yet again!
