pg_resetxlog should allow you to restart the database, but it's anyone's
guess as to whether the data will be corrupt. A dump and reload would
be a good idea. You also need to investigate what happened to your
pg_xlog files and take steps to make sure it doesn't happen again.
(Since this is evidently Windows, I would suggest being sure you're
using a recent/supported PG release, and take a close look at what AV
software you're using.)
