Life isn't about waiting for the storm to pass, it's about learning to dance in the rain!
I have tried both of them and have to say that Mandriva runs faster than Ubuntu on my laptop. After few days I removed Mandriva and installed Ubuntu 11.10 Alfa just for testing, it runs faster than previous version but has a lot bugs. Hope they find a solution and make Ubuntu as fast as it was Ubuntu 9.xx releases.
What I meant to type was 'antirootkit', my mistake.
And yes, there are some anti-rootkit programs for Linux.
Rootkit Hunter
chkrootkit
Tiger (Ubuntu's forum has some info on it)
OSSEC (it's homepage 404s, hence the wikilink)
When I'm under Arch or any other distro, I run chkrootkit and rootkit hunter, even though both aren't updated daily and can't detect everything. It's a case of 'Yes, I know there are rootkits, yes I know they are out there, but this will collect the most common ones'. If I wanted to live under a sea of paranoia, I'd stick to Windows and never try a new OS
However, speaking of Windows, if I can scrounge up enough money, I'll be making my desktop a dual boot, not a single, since I need a larger hard drive for all my games that I play under Windows and still have room for Linux.
