I've given up on MSN Plus.
Anyway, now I'm faced with another dilemma.

My laptop caught a virus recently which infected a lot of my files and then I realised the importance of backup. I would've lost quite a large amount of Islamic lectures I'd downloaded and PDF files, among other things. I tried copying those folders to my USB, but there wasn't enough space in it.
However, I'm not exactly knowledgeable to go about backing up everything. I tried searching on the Internet, and because I have Windows XP home edition, [And I don't own the Windows XP CD], it said I had to either buy something else or whatever.
Anyway, could someone explain how I should go about backing up my files? [In a nice cheap way] I did manage to save my laptop by using system restore, but I still want to be safe incase in the future my system crashes totally.
Do I need to get an empty CD? Another empty drive? Etc...
Jazakallah Khair.
