as restore wouldn't work properly decided to clear everything out and start again checking to see if manual scanning was available after each application /windows update was loaded. success UNTIL i did live update on norton antivirus. it would appear that the latest definitions/updates dated 27/07/2006 are causing the problem. the virus definitions shows the latest date but cause the above problem when trying to do a manual scan. the symantec support site knowledgebase doesn't help much and, as i'm concerned that i may not be protected, i may have to upgrade my av protection unless someone comes up with an answer quickly. ANYBODY????
