I have a problem with e-mails that carry a link to another site for example allowing me to track a package being sent by courier.
When I click on the link a window opens that shows many of the programs I have on my computer like Photoshop, MS Word, Paint, Adobe Reader or whatever. Then the window says "to choose the program that I want to use to openthis file" and then reads File: arnoapp373984100 ending with two characters that change each time the window opens and finally a forward slash.

Nothing I have done seems to have solved the problem. Googling arnoapp I found that it might be something to do with google earth so I uninstalled that. I tried uninstalling outlook , clearing out all the cookies and the like with three seperate cleaning programs, closing down and rebooting and then reinstalling Outlook - the problem is still there. I have spoken to Microsoft who tried to do a soft repair on Outlook which failed, they then tried to sell me a copy of outlook 2013! I have spoken to the company that provides my antivirus, internet security program. They maintain it's nothing to do with them!
I am at my wit's end can anybody please help solve my problem. I use Outlook 2007 and Firefox.
Thanks
