1. Pick your brew from the following concerning the AutoSearch parameters in Internet Explorer:
a. "How to Restore the Default AutoSearch Search Page (Q179402)."
b. "How to Add Domain Types to Autoscan List in Internet Explorer (Q182291)."
c. "How to Change the Default AutoSearch Search Page (Q198279)."
Note: Should there be an obvious first-time glitch when using search, determine what the default address is, change it to something else, and try again to see if the anomaly disappears. (Tools, Internet Options, Advanced, scroll down to the section Search from the Address bar and check the option, Just display the results in the main window.)
d. "How to Search the Internet from the Address Bar in Internet Explorer (Q221754)."
Note: But the Default search options were changed by the following MSKB article.
e. "Results Not Displayed in Search Explorer Bar When You Search From the Address Box (Q278931)."
2. For your reading pleasure, concerning the possibility of a system having been invaded, please read the information at this site.
I just bought a new keyboard, with all the shortcut buttons at the top (Internet, Help, Power, Standby, etc.). One of the buttons is "Search", but instead of opening the Find dialog, it opens Yahoo!. there is a way to change the function, but I need to know the command for opening the "Find Files and Folders" Dialog Box.
P.S. I know about the "rundll32 shell32.dll,SHFindFiles" command, but that only works in XP!
