Right, why on earth are you running as administrator? Your standard user account should be a limited one! Here's what you should do on linux: Create an admin user, then create a normal user account (limited one!). Always use the normal one, and only ever use the admin one for serious admin stuff. Then, if a program needs to admin rights, verify what it is, then authenticate.
how much space does it take up? i need a little or else i can't boot up and have to reinstall. i only have like 324 mb
... I lol'd. You can write a "virus" for any operating system. Ubuntu, Fedora, and Mint are all compiled for i386 if I remember correctly, so as long as all the libraries are binary compatible, you should have no problem dropping a binary from Mint to Ubuntu to Fedora. Quit using such a large distro and switch to Arch. You don't need an anti-virus program on Linux. All you need to do is shut off all the network services such as SMB, SSH, etc. and don't download random programs or scripts. Windows and Mac OS X have problems because there is just SO much software that wasn't written with security in mind like a larger percentage of Linux services were. Basically, it is the same as Windows: Stop being an idiot.
