Resolved Can't shut down - lost path ?

I am trying to get a new printer driver, and started by deleting the old (corrupt)one, which requires a restart. IN closing down I get an annoying pop-up window about "Rebate Manager ", so I try to get rid of that , but it won't delete entirely from C\Programs\... and then I get a message about a Tray App.which tells me thatthe path " C\Users\GEOFFR~1\AppData\Local\Temp\ etc etc can't be found . I am to verify that I have access to the location, or try to find the installation package "TrayASpp.msi "from which I can install the product Tray App.
When I look in C\Users I can find C\Users\Geoffrey... but not C\Users\Geoff~1.
The upshot of all this is that I am in a loop going round in circles.
Big cry for help !

Later - I got a window allowing me to force shut down - which I did, and then on restarting got the Rebate Informer window back, and another Tray App window saying that the feature I am trying to use is on a network resource that is unavailable.

 

Hi Arie,
I have been working my way through the directions but met a problem. The first scan - Temp File Cleaner found no problems. The GMER one ran, but presently I got a screen of blinding flashes and the message that Windows had encountered a problem and needed to shut down for safety - I forget the exact words, it all happened very quickly and then the machine shut down. I restarted and found that GMER and Temp cleaner had both disappeared from my desk-top.
So far, I have been unable to carry on, since I am now unable to connect to the internet ( with the PC where I am having problems) - this message is being sent on my lap-top which is wireless connected to the same router as the pc is connected by cable - and I have just checked the connection and even with the wireless link the download speed is over 2Mbs which is good for this area. I will have another try with the PC, , restarting etc.....

In th meantime I will reply to PeteC's questions below.

 

After restarting my PC I have been able to get back on the internet, and also found that MBAM-setup is still there , its just the short cut which has disappeared. But now I can't open my security programme in order to temporarily disable it.
I still have Rebate informer popping up, although the window does close when I X it , but I still haveThe Tray-App windopws which I can't get rid of.
Now I've got an error message about my security - I will swirtch to the Pc and try and sort it out.

 

I'm now in a chat room with Norton Security.

 

Norton Security took over my PC, and seem to have solved everything - that is , the Tray-App windows have disappeared, and so has the Rebate Informer ( cross fingers ! )
I can now go back to uninstalling the old HP printer stuff, and try and find new drivers - from the Hp of course.
Thank you both for your help. I'll mark this as resolved - and just advise others to buy Norton 360 !
