Software to enlarge pictures

I have a very old family photograph that I want to enlarge. Problem is that when I zoom them with image viewer or picture manager it gets distorted. Is there any software that I can use to enlarge it with similar picture quality.

Thanks

Well you can use a freeware software called irfanview. http://www.irfanview.com/

Use the resize/resample function with Lanczos filter for best results in enlargment.

You can use MS Paint to change image attributes to enlarge. The most easiest and fastest way.
