Hi F.,
Are you talking about programs like MS Office, etc.? You might check your library as they often have no/low cost computer classes.
And depending on the type of work you're looking for, computer skills ARE very important! In my field, (marketing, design, adv) the programs ARE important and it is essential that employees are very proficient at the programs needed to function in their job. In my case it's InDesign, Photpshop, Adobe Illustrator, etc. There is no "on the job" training!
So, since you know what programs you'd like to learn, google "program + tutorials" and you should get some results for the overall basics.
And like I said...definitely check out your local and larger public libraries!
