I have anti virus, what is it?

[zalle]

Hi,

I bought a previously owned iMac, and there is an anti-virus running. Is it supposed to be there? Is it part of the system or was it installed by the previous owner?

There is also a MacKeeper entry. Mackeeper was installed and I uninstalled it, can I get rid of it? How? Anything else I can get rid of?

Here

The very first thing you should do when you buy a second-hand Mac from "some guy" is to erase the disk and reinstall the OS.

You don't know what is on there -- through malice, ignorance or incompetence. There could be a keylogger that records your keystrokes (e.g. passwords).

Any "extra" software that they "sold" you, such as Office, Creative Suite, etc, is unlicensed if they haven't given you the disks or other means to reinstall it.

Completely agree with this, format it, start again from scratch. You may even notice a performance increase too if the bloatware software is no longer present on the Mac.
