Hi

Thank you for the quick reply.  I should have mentioned in my original email that a couple of weeks ago I did uninstall old versions of Java from all our computers, and the one we are running now 6 update 21 appears to be the most recent.  The thing that worries me is that I do full scans routinely, almost compulsively now, and I did one just the day before this trojan was detected.  I also scan on an ad hoc basis with Malwarebytes.  And  Norton/Malwarebytes don't seem to think the files are trojans when I run a file-level scan.   Could it be a false positive?  Our web-surfing is really pretty limited.   I tried not having Java installed at all, but there were a few things my husband needed that require it.

Thanks again

Jen
