System runs slow on start up and shut down

That is true.. as there are faults and fame of any particular company whome created it, since nothing can be perfect.

But for humor-sake, there is one: Free(C) Internet Security. Included is AVG, Ad-Aware, Spybot Search & Destroy, and you get a choice of having Kerio Personal Firewall or Zonalarm Free as your firewall. All for the price of $0*

*Does not include download fees incured by your ISP yada yada...

I made a spelling mistake, incase you couldn't find it. its Kerio not Keiro.. note the "i" placing . But i got you the link for it^. KPF will let you set automatic permissions, as well as "always ask", and the Deny option as well, and you can change it freely in the program. Although the website says its pay-to-use type of thing, and has an evaluation period download, after the 30 day period it will just disable one feature of the firewall (just web filtering, which i doubt you'd probably use, since i dont have a clue what thats for anyways) and you can still use it and make ajustments as you wish..
