In the error message that u get, click on "details button". Look for the entry that says "module name". If it says winshow.dll do the following.
click on start, run type cmd, hit ok
go to the following directory c:\windows\system
type in the following command
regsvr32 /u winshow.dll
this is a spyware that is creating a lot of problem these days
hope this works
One disk to rule them all,
One disk to bind them,
One disk to hold the files
And in the darkness grind \'em.
