These bastards created files and links at the top of my favorites
which I cant get rid of.. Any help?

Probably instaled spyware:
To remove it: start - settings - control panel - add or remove programs.

There is the list of installed programs, which you can unistall. This
one is some "......  bar"

If this won´t work, use some antispyware program eg.

Its a sign of spyware infection.
Download any free antispyware program to scan you computer: Ad aware,
spybot, MS antispyware.
If they don't help choose from wide range of commercial products.
Beware there are lots of programs which are not recommended because of
poor quality or intolerant techniques. Visit corrupt antispyware link
to see the list:

try this:

in IE (internet explorer) go to the top on the tool bar wheres it says
"TOOLS" then go to "MANAGE ADD-ONS" make sure its selected on "addons
