My mum deleted my firewall..?

I let my mum use my computer, and lately i've had a message pop up saying that i've got to clear my files because i havent got enough memory, etc... i hadn't got around to doing it, and so she did it for me and deleted my firewall/antivirus thing! So does anyone know any sites where i can get it back for free? I used to use etrust before she deleted it!!!

Thank you...

Do a backup restore for the date before she fixed your computer

If you still have the cd, just reinstall them.

If you haven't you can go to a torrentsite and download them there. (you already paid for the software, so you can download it, i think)

Or use free alternatives.

Like avg or avast for anti-virus protection

edit: ccleaner is a good free software to speed the pc up quite a bit. It also removes rubbish from the computer. It once removed over 1gb rubbish files from my computer, so if you are low on harddisk space, it can help you out alot.

ad-aware and spybot for anti-spyware

spyware blaster for spyware prevention

zonealarm or comodo firewall
Try downloading everything you need from http://www.download.com
No ides on etrust, but Zone alarm is free. Comodo is free. There a few others that are free and good.

try the first one and see if it'll let you download it and if it doesnt try the other one
Some ISP's give it away.
