what is OS
Operational System. You already answered (windows xp) 
this was there i could not copy and paste
You're not suppose to copy & paste.
Probably you can send the last file there attached in an email.
If it's too big, you can use 7zip (freeware) to pack it (www.7-zip.org) 
It is operating sustem... doesnt matter
Tanya, it could also be a ram issue, my computer has a bad RAM stick - that means that some parts of the ram can be 'written' to. But once the computer tries to 'read' again what it just 'wrote', it is gone. This can cause the computer to shut down any program that used a bad part of your memory. This means that if your computer has a heavy task ( like avast ) and you never use other heavy tasks, like games or video compressing, it will seem like avast is the problem, what probably is happening is that windows writes a file to the RAM, wants it back, reads its missing (reads nothing at all) and shuts down as a safety issue. It got me that far that im going to buy new ram one of these days.
Other 'strange' things that may occur are:
- Randomly closing programs (most of the time the 'heavy' stuff)
- strange messages when your laptop is shutting down (most of the time when you used your laptop for a longer period of time.)
To avaid this you could try to run avast right after you booted the laptop, there is a minor possibility this works.
Also if you have an older laptop it could be your ram going bad, with a newer one (like my computer) you want to (ab)use your warranty and study on this, explain it to the salesman, who doesnt know anything, and then tell him it must be your RAM.
Prepare... RAM for laptops is quite expensive if you fail to fool him and (almost) EVERYTHING mentioned above occurs. You could also buy more RAM for fun if money is not a problem of course, but i dont want you spending money unnecessarily.
