I'm having a problem with my laptop. When I open Internet Explorer the search window/bar automatically fills with different characters. If I open MS Word, characters are also automatically typed. The characters are gibberish and the automatic typing occurs periodically. Also, it is taking a long time for my system to boot up. I am running Vista and NAV Internet Security 2009 but, to date, they have not detected any problems.
I am not sure what this is (Trojan? virus?) or how to go about trying to solve the issue.
Any suggestions are appreciated.
