NTFS virus protection?

[themanwhowas]

hello.

How do NTFS permissions effect virus performance? i mean like do virus's conform to the same ACL as everyone else?

If i set all folders and files the read permission and set deny for everything else for example, apart from my system being unusable to me, is it impervious to virus attacks also? or do they somehow get around the permissions?

thanks

P.S i dont have a virus problem. i'm just curious

If you can't boot the pc - you can't get a virus

You could maybe run a pc and do some things by booting off a Linux cd and Not having a hard drive...

ok bad example. lets say that i have read permissions set on a folder named "test" and deny set for all other permissions. I have a "friend" who creates a virus that corrupts all files in any folders with the name "test". This chum of mine doesnt know any of my computer passwords. Somehow he disables all of my anti virus software and gets this virus onto my pc. what's the score with my files?

A virus can't do anything that you can't do.

Note that if you're running as a local administrator (or otherwise have the backup files and folders right), you can override ACLs at will. Also, if you're listed as the owner of an object, you can change the ACL at any time.

Ditto if the hostile code gets on your system by exploiting a service or something that's running as LocalSystem -- SYSTEM is a rather powerful entity.

But if you're running as a regular user, any virus you run is limited to messing with things you have permission to or are listed as the owner of.
