Hello All,
Can you please advise if this is a problem, or should I just ignore it?
The error message then reads:
Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied. For more information see Help.
As, at the time, the only programme running was Luke Filewalker Avira AntiVir, I thought this message was a bit over the top.
I have a 2 year old machine running XP and it has heaps of room.
Thank you,
Jean

This problem seems to be happening a lot lately ...
Copy and Paste the key bit of the error message into a Google Search.... one of the many hits is this one ..

Virtual = of essence, but not in fact....
all applications can address up to 4Gig of memory addresses.
no applications are allowed to access Real memory (RAM) directly.
Windows Supervisory code manages the Memory (RAM) resource and allocates 'pages' of RAM for an application ...... to hold its program code and data whilst its actually executing.
When multiple applications are running, Windows 'pages out' (swaps out) the data being used in RAM by an application to disk .... and then allocates the RAM pages to another application or Windows Process .... which then gets swapped back into RAM...
Soooo, if things are pretty busy and an application is referencing a lot of virtual addresses, the Page File on Disk has to be big enough to cope.
The rule of Thumb is 1.5 * RAM size.
The gist of the article I read is that an error is actually occuring causing 'memory leak', and that triggers XP into thinking that the Page file on disk isnt big enough ...

You may like to check how much disk space you have.
I normally try to run with my disk no more than about 3/4 full.
If its nearly full then that is probably your problem.
If not, you can safely ignore the problem but try doing a few adware/virus scans etc, there might be something lurking.  .
If it happens again it would be a good idea to restart your PC fairly soon afterwards.
If it keeps on happening, get back to us and we'll have another think.

Thank you all for the suggestions. I am about to leave for work, so will look at it this evening.

A memory leak is like the clothes on the floor of a teenagers bedroom. 
Whenever a program wants a new chunk of memory it ask the system for some - like taking a tee shirt out of a drawer and putting it on. When the tee shirt is no longer required it should be put in the laundry basket which, ultimately, will get it washed and put back in the drawer. Sadly, badly written programs - like teenagers - sometimes just drop their clothes on the floor.
The result, a messy room with a thick layer of clothes on the floor and not enough in the drawers.
Most systems can handle that for a while but eventually the supply of tee shirts runs out and the system must go to the store to buy new ones, and this is what Vista is doing when it shows this message.
One small point to remember. Whenever you restart your pc its like a spring clean. All the rooms start clean and fresh and all the tee shirts are clean and in drawers. If, however, you hibernate your computer, the mess on the floor doesn't get cleaned up.
So, dinie,
'how do you check if something is leaking memory': there are ways of finding out how many tee shirts are in drawers (free memory) but if you try to venture into a teenagers room to gauge the depth of the 'clothes layer' you are in for a major argument.
how would you correct it: upgrade your teenager  or restart regularly.
