Unable to do the copy and paste but have HP pavilion . For a couple of weeks when I click to leave a site sometimes a box comes up " Are you sure you want to leave this site" . We are all used to this however this one is different , under the question "Are You Sure ...." comes the word false in small print and at that point the computer will do nothing even if I click on yes or no . Then the computer must be shut down without going thru the proper procedures . This must be some kind of virus .
