in SC 9.0, I cannot reset the time of day for a scheduled scan; it is set to 4:00 A.M. on Friday, which is inconvenient for me. If I try to change the time, the 'Apply' button is greyed out. The 'Reset' button has no effect.
I meant, are you signed into Windows as a limited user or one with Administrative authority?
Also what McAfee products do you have installed? Double-click the taskbar icon and then in Security Center click "About" at the lower right-hand corner and post the verion number for each module. You may have to scroll down to see them all.
Also I notice IE6, you should be using IE7 as it is safer and faster, so the question there is, is your Windows totally up to date otherwise, with both critical and non-critical updates?
Try running the Virtual Mechanic linked in my signature and post what it says along with the session ID #.
Well, as both Microsoft and McAfee Security Center rely upon Internet Explorer I suggest you at least update that to IE7. Download is here: http://www.microsoft.com/windows/downloads/ie/getitnow.mspx (Little known fact: McAfee Security Center is, in fact, an IE webpage, albeit internal. I also suggest that you set Windows Update to get updates for everything using Microsoft Updates, if you haven't already.
Also in IE make sure of the following: If you are running Internet Explorer 7 go to Tools/Internet Options/Advanced and click the Reset button. OK and exit, close and reopen IE7. You will have to-enable all the browser add-ons. If Internet Explorer 6 - go to Tools/Internet Options.. General tab: clear cookies, history and temporary files Security tab: set all zones to default Content tab: disable Content Advisor Advanced tab: set to default. OK and exit.
Scan you machine for malware using the free version of this tool: http://www.superantispyware.com/supe...freevspro.html You can easily tell if you have Administrative authority by going to Control Panel/User Accounts (whatever its called, I'm in Windows 7 right now) and checking your name.
