Have this problem. When entering certain letters on keyboard in windows for certain applications such as Internet Explorer, notepad and microsoft word, these letters are not entered in these applications, but for example, for certain letters the following happens instead.
M - minimises application,
L - presents log-on user screen.
E - opens up windows explorer.
I think this could be a virus. For example, I wish to type www.google.com but can only get as far as www.goog and when I type the l the log-on user screen appears. Any ideas what this is? Thanks.
