Hard to tell without know your OS

Anyway the old Greycstoration plugin still work very well in gimp 2.6

Gmic is much more, it include other 300 filters and may look more complex (even if has a better Gui then GreyC )..a price for all the options that may offer) ..

As Michael says are not checked at all

But similar problem will be quickly reported, as comment or here, or in some gimp forum

And till now as far i know was not a single case of infected files
