Ok as stated in the title I am unable to run HijackThis on my computer. I'm currently using Windows XP Service Pack 3.

The issues I'm getting are adware popups all the time and I am unable to run any installed anti-virus or anti-spyware programs, various portable apps work, but are unable to actually do anything as they get denied access. I get a message indicating that I do not have sufficient privileges. When I tried to run HijackThis, it opened, but when I tried to get the log it just quit.

Thanks in advance for the help.
