My friend wrote me this:
In any program (safari, excel, powerpoint
etc. it will scroll down uncontrollably and sometimes
when trying to type (for example in a search engine or
a password to log in) it will type " 9.ol/ or
something similar (but only using those particular
characters). Also, sometimes it will just go in and
out of the "window pane view" when I have multiple
windows opened. It does all of this uncontrollably
and/or at the same time. I remember that you told me
to download all the security updates, I did this and
was still having problems after. That was yesterday,
and now today it is fine! What does that mean? You
told me that viruses for MAC are rare, but could this
be a virus? One more thing, I noticed that it started
after I downloaded a large powerpoint file from
someone elses USB. Could this file have had a virus?
