All settings lost

  Done and dusted 16:08 20 May 2010

My computer is doing crazy things. It has lost all the settings I have input i.e. ICC profiles for Photoshop. It has removed my identities in Outlook Express. It has changed my home page on the internet to MSN. It has changed the appearance of my desktop and removed shortcuts from it. I have lost all my Internet Favourites. In fact everything I seem to have 'personalised' has been lost. I get a warning bar near to the top of the page telling me my security settings need fixing to access the internet. I am currently working on another user account to overcome this and because my user account (administrator) is completely erratic. I thought I may have a virus but Norton 360 seems to be working fine and hasn't detected anything. Help please and basic help at that because I'm no techie!

OK, any other ideas anyone?

Well,what did it find, and did it solve your problem?
It's not clear as you are still asking for other ideas.

System restore to a time before you got the warning bar.

The warning bar sounds like malware.

Unfortunately I can't log onto the internet as administrator to download the program like you said - it won't let me and when I try to download as another user it says only the administrator can do that. Also when I log on to the administrator account when I press the key to type @ it types " and vice versa. Is it a virus? Is it malware? Why isn't Norton 360 detecting it?

Can you download MWB onto a pen drive using a friends computer?
Have you tried a system restore? (Do it from Safe Mode)

Great idea - I'll try it with my son's laptop if and when he arrives home. Haven't tried system restore as I haven't created back up since I first had the computer (what an idiot!) and I don't really want to go that far back. Thanks for your help and watch this space.

What Operating System are you using?
It may be quicker and easier to do a Repair Installation. For example Vistaclick here
But before that it's worth trying a system File Check, this will replace any damaged or corrupt system Files.
Open the command Prompt using right click and choose "Run as Administator" at the prompt type sfc /scannow the hit Enter

It sounds like you have an infection. Is your anti-virus up to date and have you run a scan recently?

The computer will have created System Restore points automatically from time to time, without you doing anything; so there may be one not too far back. But make sure you use one that is definitely before your problem began.
