An update from Norton has been killing TiddlyWiki files. All TiddlyWikis
are incorrectly indentified as having W32.Feebs, not just those from
Tiddlyspot. See this thread
for more information.
Someone said they were able to restore their TW from the quarantine
files area, even though Norton told him that it had deleted the file.
So if you had local unsaved modifications you might be able to recover
I believe they quickly released another update that has fixed the problem but for many users the damage was done and for some it has been devastating. This is a terrible mistake from Norton. Our sympathy to those affected. I hope that your data is safe. And please take this as a reminder to always make secure backups of all your important stuff.
