I'm running 2 users on XP home edition. MC Virusscan version 6.01 with the latest definitions 4.0.4178 runs fine on my settings. However, when my other user logs out of MSOutlook, the error message pops up: ACTIVITY LOG ACCESS ERROR , stating " Unable to open the activity log file c:/...etc Webmail.txt. This file is either write protected or locked by another application. RETRY/ CANCEL This happens when no other app is running and just locks on the screen so cant even select RETRY OR CANCEL?? I have had probs with this before and have had to remove virusscan and reinstall about 3 times and am getting a bit fed up. The only solution I can see is to disable virus on Outlook for this users setting (but I know I dont wanna do this!) any ideas whattsup??
