Free Anti Spam Software

What is a good anti spam (not antivirus or antispyware) program I can recommend to a select group of customers?

I some of my off time I volunteer to help groups of senior citizens with keeping their PCs working properly. As you know SPAM is a major problem to everybody. But it is really upsetting to this particular group, as for many of them this is the only way they can keep in touch with their families.
I already have the PCs protected from viruses and spyware. I am just interested in anti spam that does Outlook and Outlook Express on XP and Microsoft Mail on Vista.

I like to compare free and paid ones because some of my customers don’t have a lot of money. And cost is a major factor here because most of these people are living on a fix income.

I live in the UK, and though I’ve never built a PC before I am willing to build myself a £900 gaming rig, with a good processor and graphic card, good memory and a blu-ray player.

I have been on some UK websites and wow the prices are good but then I hear things like, “their after sales server is terrible”. For example, overclockers.co.uk has great prices but they’re considered “cowboys” and their manager is extremely rude and they spell out continuous lies. That to me, by anyones standard is an utter disgrace.

I’d rather have nothing as mentioned of the above. I do indeed want to use a UK website which has good prices, but I also want a website that has good after sales support and if something is faulty will be RMA’d or whatever it’s called. Replaced or something?

On the other hand. When I went to www.scan.co.uk another surprise hit me. A cheaper MSI 790FX-GD70 AMD 790FX AM3 Socket motherboard even cheaper than overclockers.co.uk however, their RAM was DOUBLE THE PRICE! Can you believe it!? I am not paying 140 quid for Dual Channel DDR3, that is beyond belief!

Then came delivery issues, I’ve read Overclockers.co.uk has disgraceful delivery and coupled with a nasty arse manager wouldn’t go down great. Then there is Aria which has expensive delivery. Then there is www.scan.co.uk which requires you to sign up to another website’s forum and post 20 or more times (without it being considered spam) to avoid a £20 delivery charge.

I want a website which has good prices, great after sales support, good delivery (possibly free) and can have faulty equiptment replaced, and isn’t run by cowboys who insult you if you ring up and tell them the faults with your hardware.

Is there even such a website or am being unrealistic?

This is my first build, and I don’t know if it’s risky. I will be getting Arctic Silver of some kind and two anti static bands one for myself and one as a replacement or for my father.

I know Intel is powerful but it’s great at number crunching and when AMD comes along in the gaming arena I’ve seen in real-life test the AMD Phenom II X4 955 out-beat the Core i7 920. So that’s the processor picked. The mobo above amazingly which I found is considered better and giving 5/5 everywhere I’ve been, every forum member I spoke to says they would pick it over the Crosshair III Formula. So that’s sorted.

So now it’s just time I find a DECENT buyer with good prices, aftersales and delivery.

I only have £800-900 - I originally was going to get it pre-built by PCspecialist.co.uk or Arbico.co.uk but it turned out the mobos for selection were absolutely useless. I then decided Intel but the money started adding up.

I know this question is long but does anybody have any tips for a noob gaming RIG builder. I’m not good with fiddling things and I’m worried about applying thermal paste to the CPU and heatsink. I’m worried I’ll screw it up. Also where else does thermal paste go, could someone list all the places (maybe for this build I will list below) thermal paste will go.

Thanks to everyone who answers, I will read your answers shortly, most informative and thorough will get their points. Thanks again.

FX - the noob PC builder on a 900 max budget!
note: Buying In GPB £££ Not Dollas. Newegg.com does not ship to the UK so don’t mention it. Feel free to E-mail me folks. Do not IM. I can communicate via e-mail to people on a regular basis so this would be beneficial to the advice I recieve and my gratitude towards you.
Dean. I’m not made of money bud. £800 preferably - £900 Max. lol an I’m on AMD for budget reasons but they perform and overclock well compared to the Core i7 920 but is so many 100’s of pounds cheaper than the i7’s. Remember my budget mate. Edit your answer if need be. Thanks

or Two Radeon 4870’s in Dual X16 Crossfire.

PEACE
AHHH that was the one. CCL has the double price RAM. I went on there earlier, their website is useless, they won’t win the award for 09 I can bet. Sorry mate, thanks anyway
This build is completely from Scratch, from the ground up. This PC I am on is like 5 years old and is useless. This is my first build as well remember. Please take everything said into account this message is long enough already. Thanks
Info. I know about System Specifications. I know what’s good and what’s bad. I’m asking simply about Online Retailers and some advice on building my computer.
