Here is a link to explain Safe Mode more thoroughly. AVG should have no effect on this.
1. I can't reboot in safe mode sad.gif I press F8 and keep it pressed but no. Tried several times. Could it be cos I've got Grisoft installed to scan?
This is a bug in the program which should be fixed in the next version. As long as your Windows is fully updated, you can ignore those entries.
2. When I run Spybot it always finds DSO Exploit and try as I may I cannot remove it. it says its in the folder Hkey_Users\default\software\Microsft\Windows which I also tried to remove (can I? should I? or is it basic to the system??) and failed to do so.
You can remove that entry if you do not use Wild Tangent to play games, for screensavers etc.
3. In Add/Remove Programmes I can see "Wild Tangent Web Driver" Shoulld I remove this or is it now spyware?
Not sure for question 4.
