Yes that's right. I use this feature. But i'm a developer and design some
kind of software at home(including creating of installation packets). There
were about 6 times during last 2 years when i have to search all *.exe and
*.dll in my work disk partition and delete them, because of viruses. Now i'm
doing things in the next way: when i get a software packet - i'm zipping it,
when i'm stopping developing something - i'm changing permission for myself
to provide read-only access.
Yes of course it's a decision - but is it convinient?
So i propose a thing that when something tries to modify *.exe or *.dll
software shield should create window for user with alert: to allow or not to
allow for this process to alter binaries. If Yes, shield should ask user
wheather to always allow for this software to change it or not. If yes
anitivirus should save md5 summ of process it's name and location
Also as i'm a user i don't make updates. When I wan't to update something i
run process with administrator's privileges. Not as user
For Linux i don't know but i think there's analog situation.
Also I discovered that some processes tries to load their libraries in
explorer by configuring my registry key(of couse with user privileges)
So maybe it's good to disallow altering such registry keys (or allowing this
with making notification for user)
