Internet Explorer problem

I have been getting error messages when going to certain websites : "your
browser is not active x enabled" (or something to the same effect.) So I
went into "tools"- "internet options" and clicked "enable" for all active x
entries. But still the webpages gave the same error message. Looking in
"control panel-add remove programs" , there is no longer an entry titled
"Internet Explorer 6 and Internet Tools", so I could not do the "repair
Internet Explorer" option. There is an entry called "Internet Explorer
Q831167". When I chose to uninstall that entry, the old entry (Internet
Explorer 6 and Internet Tools) did not come back. Doing an update via
Windows Update website, the entry IE Q831167 came back, but not the original
entry which is Internet Explorer 6 and Tools. Any one know how to get it
back?
