I want to install trend micro antivirus, but every time i try to install it it says norton 2003 is interupting it. Then i try to uninstall norton 03 and it says "Fatal Eror". Anyone knows what is causing this and how I can fix it?
Your fatal error was probably using Norton in the first place. Anyway, go into the registry (run > open: regedit) and remove all keys relating to Symantec or Norton (I'm assuming you don't have any other software from Symantec installed). Restart the machine and then you should be able to install Trend Micro, which is good stuff. Just remember, don't install a new antivirus without removing the old one first. They don't play well together.
