This is getting silly, there are more problems on this laptop now than ever there was and I can hardly type anything as the text on screen just won't keep up with me .........
Fair enough. I think the reason OTL won't work and we had problems getting the online AV to work are related to Malwarebytes. It is a great program but it does interfere with our tools... it is trying to protect your machine.
Normally we would ask you to uninstall it then carry out the actions sought before reinstalling it.
Having said that, I don't see malware on your machine and as you say, we are not really fixing your problem. The bits and peices that OTL script was going to clear are just left overs after the AVG uninistall. They leave a mess behind them. Just orphans though that won't effect your machine.
I think we should move on from the malware possibility.
Turning to your typing problem, after a bit of research, I found that a lot of people with laptops have the same similar problems to you. One which is not quite the same but was typical of the sort of thing was this:
"The Dell Studio XPS laptop series (both 13 and 15.5" variety) seem to have the UP arrow immediately to the right of a shortened Shift key. I'm an excellent "touch typist" on a standard keyboard, but have had a similar problem with most smaller laptops, where the "unpredictable" upward cursor movement happens (for me at least) when I try to hit the right shift key, but really hit the UP arrow. My best guess is that's what's causing your jumping cursor."
Not quite your one but close. I am wondering if the small keyboard is the problem. It certainly was for me. I touch type and when I still worked used a laptop but found I had problems with accuracy. My solution was to use a normal keyboard attached to the laptop via the USB port. Worked for me.
I don't think there is anything specifically wrong with your machine but if you wanted to investigate further you could try Dell Support.
We have a couple of last steps to perform and then you're all set.
- Double-click OTL.exe to run it. (Vista users, please right click on OTL.exe and select "Run as an Administrator")
- Click on the CleanUp! button
- You will be asked to reboot the machine to finish the Cleanup process. If you are asked to reboot the machine choose Yes.
Folders/Files left on your desktop after running CleanUp can be deleted.

Have a safe and happy computing day!
