Hi Glenn, sorry I never got back to you. Been one thing after another. I had a good go at the anti virus script this week, but in the end I just gave up as I couldn't get it to work properly. I will get my sister who is a computer programmer to show me what I am doing wrong as programming is simply not my forte! And I don't have time!

But thank you especially for the debugging line. Very useful to know how to return the results using two lines of code instead of what I was doing!

On a completely different topic, I have been researching UPS's as I know almost nothing about them. After several weeks research I have decided to buy Eaton UPS's. One thing that stood out is how well Eaton works with generators which may be of interest to those in the US where hurricanes frequently prevail as apparently there are a lot of issues with APC and Tripplite line interactive UPS and generators down to the very narrow frequency range - or something to that effect. So if anyone is looking at UPS's then based on my humble research I think I would recommend Eaton. When I actually buy one, I will let you know what I think of them although as I don't really work with UPS's it will be difficult to compare them to anything else! A great forum for learning about UPS is the website spiceworks.
