Spyware? Trojan? Malware? Types on its own

I have a friend who's email seems to type on its own.  He uses AOL.  Also, I heard of someone with a similar problem when using a search engine and the search phrase is typed on its own.... almost like there is a ghost sitting there typing or someone is controlling there computer.  Basically if she types a word and then lets the computer just sit, it starts typing its own words.  This is an example of something that it just typed:
 
hkjhand the I how I have were a file and the to the and if it did in the home

The only thing she typed was the "hkjh".  Anyone ever heard of this or has a solution?  Thanks!
