Sorry for a long reply, I can't say I'm visiting deviant so often now.
What about viruses, it's common that some virus protection software is a bit paranoid about such utilities like Vista Anthracite Pack. Pay your attention, that this tool modifies a lot of system files (changing icons, BMPs, AVIs, etc), so it can seem suspicious for a virus protection software.
What to do in that situation?
I can recommend the virus total site, it isn't a 100% warranty for sure (who can give that?) but I want to believe, that it's the most comprehensive service for the moment.
Just for example, look here:The current result is 16/41 39.02%
, or (it will be better), upload your own copy of a file and re-analyze it again.
Pay your attention, that most of anti virus software reports about WFPDisabler, for sure, it is here,
no ways to change icons, pictures, etc, without turning WFP off.
Hope, its help,
