It is unlikely that the slowness is caused by a virus. There are not very many Linux viruses out there and they are hard to spread and even harder to get them to cause any damage. However, to answer your question there are virus scanners for Linux. ClamAV is the main one. Open Synaptic Package Manager (system - admin) and search for "clamav" and install it. It will pull down a few more dependencies so accept them.
However, I'd be willing to bet there is a different reason for the slowness. First, lets just see if any app is using a lot of CPU and/or memory. Open a terminal (applications - accessories) and type "top" (no quotes). See what sort of CPU usage you have and if any app is using a lot. Unless something is working hard for some reason, most apps use very little of the CPU. If you see something over 10% for any app, lets explore it and see if it's misbehaving. You can press ctrl-c when you see the high percentage and then copy and past the output here.

I don't think this is a virus. But If you want to install an antivirus anyway, you can find a list here:

Okay, I seem to have a lot of stuff going on with the
cpu "id" (no quotes.) It shows between 91-100% at any
one time. When I installed Ubuntu, I kept my Windows
applications--I'm wondering if this is where the
problem lies. As I don't speak Linux, I'm always a bit
in the dark when it comes to things like this. Thanks,
I appreciate any help you could pass on! Tre

That's what I expected. I'd open a new question for this since it's probably not related to a virus. Be sure to include the output of top so we can see what app or apps are using a lot of CPU.

leebrendalee,
Please do not add to a 'solved' report unless it is yours. This is not the case. Please post a new question should you require, so that you can get the most attention, many of us ignore 'solved' threads since they are 'solved'.
To answer your question, two users is normal. This is not a concern you should have and absolutely does not indicate any type of 'security' issue.
