Thank you so much to all the people who have posted in this thread.
When i came back from a long holiday i turned my laptop on for the first time on 25th August and found the above mentioned Click to run pop up. I thought it suspicious but after all the searches ( internal and external) it appears to be genuine but very
bad promoted by the program creators. As i hardly ever use Microsoft Office on this laptop i followed the well detailed instructions given by you all here and opened a Word file, clicked Help/ Update Options and disabled the updates. Got the usual pop up window
asking if i want this program to make changes to the hardrive to which i clicked Yes and then got a notification "This program will no longer be updated". All ok now. No more pop ups.
I had the 5000 version, not the 5001. Am on Windows 7.
Thanks again
Cris
