Hello Alan and welcome to Seven Forums.

If I'm understanding your question, you want to know how you can tell if your computer is infected when you don't have any anti-virus program installed. I went to a couple of respected anti-virus company websites to see what they have to say:

Symptoms | Infected Computer

Computer Virus Symptoms

How To Detect Malware Infection On Your Computer | Lavasoft

And a couple of general information articles:

HowStuffWorks "How to Know if Your Computer is Infected with a Virus"

How can I tell if my computer has a virus?

How to tell if your computer is infected with spyware

How to prevent and remove viruses and other malware

Personally, if you're on the internet, there's no good reason to operate a computer without an anti-virus suite. Even if you're not connected to the internet you should still have an anti-virus suite installed. Maybe someone shares a flash drive with you and it has music or videos on it. Maybe it also contains a virus or other malware. There are so many free products to choose from. Here's a Seven Forums' thread:

Or you can google best free antivirus products and you will find all kinds of reviews. Here's just one:

If I misunderstood your question, I sincerely apologize. If you give a bit more info about what it is you're trying to find out...

Hi,

To test your anti-virus, download these EICAR test files and see if your anti-virus detects them:

Download ° EICAR - European Expert Group for IT-Security

Note : these are only test files, not actual malware.

Regards,
Golden

I'm really not sure what you mean without a program.
All anti virus programs are programs.
If your computer acts in any fashion that isn't normal it could be a indication of a infection. You would be the one to know if things are different.
If you have any doubts you can run a complete updated scan with MSE. Here are some other programs you can scan with.
