Banger, first off, make a back up of everything that you'd miss.
Right now.
Then repeat every week.......
Onto CD or DVD, and keep them safe, ok????
Done that????
Good.
It really scares me how many people have years worths of digi pics, documents, emails, schoolwork etc etc on their PC's but don't back it all up....absolute madness!!!
As for the conflict you've got in the progs, it's a bit like asking your two big brothers to mind the door at a party, then hiring two professional bouncers to mind the door as well, and being surprisded when the bouncers come in and dump yer brothers at your feet 'cos they were 'suspect'.
Unless you know how to disable progs and use several alternatives to cover all the bases, stick with just one...(of each sort...see below

)...but with a few clicks, you should be able to pretty much protect your PC .
There are several different types of security prog......for a 'normal' user lilke yourself, there are three .......Firewall, Antivirus and anti spyware/adware.
Don't use Norton for any of it ...really, trust me on this one, just don't.....
I don't think you'll get many people slagging you off if you use the following;
Firewall......Zonealarm...it's free, it's very good, it stops slimy spotty 16 yr olds breaking in to your PC and nicking your bank details, and it controls what progs can 'speak' to the internet, as well as other machines that you might have networked to your main PC.
Anti Virus..I use AVG (again, it's free)....it sits there all the time, invisibly, it checks all your emails, downloads, websites, it updates every day with new info aboutthe latest virii and it's free.
Did I mention it's free???
ANTI spyware software will stop the extra nasty little progs that can get into your browser and onto your PC..they'll report your browsing habits, pop up adverts and do various things that you don't want them to......at the moment, Microsoft's (free) Windows defender prog seems to be pretty good.....Spybot, Adaware and various others are also good, but only have one running at a time......If I were you, I'd run MS's defender...then you can run the others if you have a specific problem that it hasn't sorted.
It's also free BTW
