I'm not sure about what DRM you are talking about but if you use a good firewall and anti-virus/malware scanners (Comodo firewall and avast! anti-virus/malware are both free) then you won't have any trouble. I use those and have no problems. The scanner catches whatever tries and stops it. I've been virus/trojan free for years on XP, Vista and win 7.
Haha...*gasp* Say it ain't so..
I am SHOCKED.
Aghast!
ROFLMAO.
That's the benefit of running an obscure, unpopular OS. No one bothers writing malware for it. I miss OS/2. or the C=64, come to think of it.
Just like when I had a Studebaker as a kid. Nobody ever stole the hubcaps.
