Use Hijackthis & mark the following entry for removal, then go & find the file and delete it.
You will probably NEED to set windows explorer to show all files, hidden etc.

I Googled filost... 71,000 returns popped up.i've removed that line from hijack. i went looking for the vb.dll file but it wont let me delete it, it says access denied, it may be protected or in use. i cant see its protected and shut everything else down and it still wont budge.

will my deleting the line in hijack do the job? ill have to see if my screen still appears.
i read somewhere that you can delete stuff from the registry - could this be an option if it still keeps happening?

PhilThe file you need to delete is vbsys2.dll NOT vb.dll.
Google for killbox & use it to delete with.after deleting the line through hijack - it SEEMS (touch wood) to have worked! many thanksThanks for the feedback Phill.
