Q1xtlstD.exe

I have an old IBM R51 laptop. A few days ago IE wanted to upgrade itself from version 7 to IE8. Since that day, my laptop run slow, cannot watch BS player (or other - slide, freeze etc.). I have removed IE8 and downgraded IE back to IE7, but problems still remained. and since that day In my task manager, in processes, I have somethimes 30 Q1xtlstD.exe (user name: SYSTEM) file, and usualy it shows that I`m running iexplorer thought I`m not. Is it some kind of virus or? Thanks in advance!
