Hi guys, Finally decided to try and get another A/V disk.After trying to install it and it failing it sent me to the symantec corp. website and allowed me to download a fix that completely removed all known traces of NAV throughout my entire system. as mcallisb said i may have deleted something i shouldnt have, but luckily enough the fix did exactly what it said on the tin and fixed it. my system is working perfect now, and i managed to reinstall a new internet security system. Thanx for the help guys!
