Because of this,C:/Progra1\ MyWebs"1\bar\3bin\F3scrctr.dll , I think that you have a hijacker installed on your computer called MyWebSearch Toolbar.

 

MyWebSearch Toolbar Description:

 

MyWebSearch is a toolbar that quite a few third party software developers bundle with their "free" software. It is a search and error page hijacker that can be fairly tricky to remove. Smileycentral.com is probably the largest website pushing this toolbar. This toolbar will quite likely slow the speed of IE web browsing and searching due to the hijackings

I am not an expert on removing this but here is a link for you.

Look at that page and see if you have any of the files that they are desribing.  You may also want to visit Dell's HijackThis forum and post over there for some expert advice.
