Yes, you can delete it. It has been labeled as Malware. It probably came with some other program you installed on you computer. Many legitimate programs also come with add on programs attached. These programs only install if you let them. At some point in the installation process, you will see a screen, that has a CheckBox, that is already checked, and if you don't un-check it, it will install. I've only found 2 that are not malicious, Ask.com Toolbar, and Google Toolbar. Just watch when you install another good program, and un-check the box.
