I'd have thought that a search for "waiting for 7.7.7.0" would be the thing to try, then. Plenty of results. One example of many:

But see also

I'm sure there's a great deal more to be found, but you can do that for yourself. Of course, you may have other infections too. Best read up on it all before deleting anything. Let us know how you get on. Reinstalls should be a last resort, though an awful lot of people panic and do them unnecessarily.
