This is pasted in from a text file.

Since yesterday I have had to cut and paste into any online page such
as Blogger and so on. This is a big hassle for me as I work part-time
editing an online trade magazine.

It's not my keyboard. I can type ok in text files, Outlook Express,
Word, etc. Just not online. Apparently some hacker is playing with my
keyboard strokes, perhaps to break into my accounts (bank and
otherwise). I have scanned my computer to no avail. Any ideas please?

Update: It's just in Firefox, not Internet Explorer

The first thing I would to is try and clear your cache and cookies:

If that doesn't work, then perhaps try and re-install Firefox from the
Mozilla website: http://www.mozilla.com/en-US/firefox/

If for whatever reason that does not fix the problem, then I am sure
the Mozilla team would like to hear about this strange little bug.
