Free Anti Spam Software

I wanted to know that if anyone know if their is a site that I can get a free anit-virus and software download for laptop(mine is a toshiba)? I don’t like to waste money on the disc in best buy or any other store, in some disc they only lasted 1 or 2 years. I don’t like to pay for a site that say free anti-virus and anti-spam, and later you have to pay for the download!!

After accidentally clicking on a side banner of a website the other day, we have been boarded with pop-ups and unwanted CRAP that just will NOT go away. It is slowing down our computer and our internet considerably. It interferes with anything and everything we try to do online. CONSTANT full-page pop-ups, and most are for anti-virus and pop-up blockers! Sometimes when we’re not even using the internet (we are always logged-on with our internet service).

I’ve already downloaded the free version of the AVG program, as well as the Yahoo! toolbar anti-spy. AVG didn’t help much, although it did find and get rid of about 10 Trojan files (I have no idea what those are…)

Thank you so much for any and all help!!!

What needs to be done to clean up and speed my pc? Also should I install free anti virus and anti spam software?

is there any free software where i can get the whole kit? (spam virus etc,)

Thank You
