For the Fuzzy issue, I have edited that section and if you followed it now, you'll be able to get by those errors. Make sure to set the password on the db and assign it to FuzzyOcr.cf under the mysql section.
As for the MS issues, the only other time I've seen that was when the harddrive was full. Check to see if your partitions are full by any chance. Also, if you run freshclam, what happens? Does it complete?
