Is a dedicated anti-dialer really needed?

Since I'm still on dial-up (hopefully only for a few months), I'm concerned with the dialer problem. I found that a-squared provides a free anti-dialer with real-time protection and I would like to know if someone had tried it and what you think about it.
Is such an application really needed if I run a good AV and a good HIPS? Basically, on my old PC (AMD Duron700-256k ram), it is a waste of memory and CPU or it could help me avoid some threat?

My security setup is:

Antivir PE
SSM full (thanks to givawayoftheday!)
Jetico V1
AVG antispyware and SuperAntiSpyware (both on demand)
Web Browser: Firefox

Thanks in advance

I'd say with ssm running(and if you know what you're doing with it) i'd say a real time anti dialer is not needed.

 

Thing is , the more memory resident programs that you run, the slower your performance. if you down downloading and would have a fear of this perhaps you should seek out thing sort of program. As farmerlee said, if you have a HIPS software running and you use it well, you "should" be ok.

 

I hope so.
Actually, I never had such a problem; only once a maliciuos web site tried to download a program on my PC, but Firefox iteself noticed it and nothing more happened.

In a poor system like mine, I''l be OK with my setup. Thanks for your advice.
