I have the same problem as that submitted by klabelle with the Internet Explorer

seems to be a double post.
here's what I posted on your other thread.
in IE6 it's not listed as manage add ons, but the functionality is still there just in a different location.
I believe it's under the advanced tab and then click on the "programs" button.
there is another way, run the program Hijack this.

do a scan and save the log file. post the results and I'd be happy to tell you how to remove the problem program. my guess is that there's a toolbar that's screwing with your internet explorer.

Thanks a lot for your immediate reply. This is the log generated by HiJackThis

so far I can see at least three toolbars installed and skype, spyware doctor, adobe, yahoo companion, etc.
try marking the checkboxes for all the O2 entries with hijack this and clicking the "fix" button. do this with internet explorer closed. I should warn you that this is permanent until you reinstall particular components, such as the google toolbar. for example hijack this won't uninstall skype from your computer, but it will break the connection between internet explorer and skype (which is usually a desirable thing and greatly speeds up IE)

Sorry for not replying before but I was Away. Just a little question before I proceed, will I still be able to use skpe? Cause at the moment I really need it!. Although I am highly suspecting that my fault is directly attributed by this program.
Thanks

yes, this may only affect skype in that it may not automatically start up, just abstain from checking any boxes that have "skype" in the line and you'll be fine.
