Based on a quick web search, these appear to be part of something called
WinTools, which, apparently, some number of people would like to know how to
remove. I commend you to also search the web. The two pieces of advice I
gleaned were first to see if you can remove WinTools in the "Add / Remove
Programs" applet in Control Panel. Second, try to remove it by other means.
Those include using a spyware removal tool, of which there are a few. Also,
anti-virus vendors are beginning to provide removal tools, so check with
your anti-virus vendor. If "Add / Remove Programs" does not work for you,
and you are unsure how to proceed with this second choice, post a reply with
an update and a request for specifics.
