Hi
i was updated my bitdef total security yesterday. but when i start the update today i see that the total update file size is 16585 kb (16.5 Mb).
then for 1 day 16.5 Mb 
for a month 495 Mb
for a year 5940 Mb ! 6GB of disk space will be eated by update files. 
i want to know if this update files will replace the old ones or they will be added separatly.
tnx
