text: internet trojans? i have a secure pc. i do get trojans coming in on other things and they get deleted by my security program (sygate). i noticed my pc was very slow so i defragmented c which was three quarters red! it defragmented a few minutes and then gave a system message that most can't be defragmented! i've never had this before. is my drive totally screwed up now? how do i prevent this from happening again? serious answers only please. =============================== do not listen to | v  kevinsminimac qoute "buy a mac"  macs are not invurnable as ppl say or want you to think, your say this because you have never seen or been hit by something.  well still does not help espically that now macs are being targeted as well.  oh yeah thank, intel and windows for unlocking more hazzardous portal door to macs new probleams.  if your a codder or an editor or something that knows computer you would know! ====================================== ohh!! that sounds bad, ahh have you first tried  installing avg anti-virus free edition (i'm not lying and i will not lie to you or anyone) it is totally free and is very powerfull.  1) get that program and install it and update it after run a  full systems test.  [in this second step, please have your computer offline or bascially remove what ever wire that you have connected to the internet]  2) run scandisk aka "error-cheacking"  to do this like how you go defrag exepct you right click on your hard drive and you go to the "properties" and  click on the tab "tools". than on the first on the list it should be there and click on it called "check now" and there should be 2 empty boxes that you can click to put check marks on "put a check mark on both" bascially click on both and after that click "start"  3) it will say you have to restart the computer and  than "log off" and "restart" and in the beganning after the  windows bios screen and windows os load up screen should come up with scan disk, you can cancel it by hitting space bar and warning do not and i mean do not stop or turn off you computer once it is doing scan disk, and give it much time as it needs. once it finishes it will automatically restart by itself, soo no touching :) please  4) go back to my computer and right click on your hard drive and click "properties" and now click on disk clean up and click it and give it time and after it shows all the menu on that list put a check mark to all the things and click clean now. let it finish, don't freak out it it takes a while, give it time.  5) now your ready for defragment! and if you still have probealm with your computer with torjans i seriously recommend you using a server internet browser, like firefox.  6) click on the links below to get avg anti-virus free edition!
