Not very technical but here goes - according to the "system" page I have a VIA C7-M Processor 1200 MHZ, 1.00GB RAM and Windows Vista Business with Service Pack 2.
The antivirus I use is Avast (the free one) plus I have the windows firewall and defender switched on.
Haven't got much intsalled on the computer apart from Adobe, Open Office, Rapport, Skype
