might be lurking in your computer, then there are 2 good spots to check:
When I use the internet (both Internet Explorer and Firefox) or try to save/open a file in MS Office, the dropdown menu will often start opening uncontrollably and repeatedly, essentially preventing me from doing anything else on the computer. In addition, when I am trying to type in Word, my words sometimes appear to automatically copy and paste themselves repeating what I've already typed. This will happen when I type even just a few letters making it impossible to work.
Has anyone else ever had this problem? Is it a virus? What can I do?
