Hi to everyone...
First of all thank you, all of you, for your care about this issue. I already bought AIS at 01.10.2010. so the licence of Avast Pro is waiting for opportunity to be used.
I make this decision because my TOSHIBA SATELLITE L10-119, Intel Celeron 1.5 GHz, 1GB RAM, XP SP3 Home works best with AIS in combination with SAS Pro.
Only SAS slows it a Little if the "Real time protection" of SAS is turned on. What is important my reinstalling of Windows with Toshiba recovery CD. After that my system goes like "FORMULA 1"
. I done this because of a lot of tests like Avast Free with Online Armor, Avast Free with Private Firewall, Avast Free With Agnitum Outpost, Avast Free with Ashampoo Firewall, AVG Internet Security, Emsisoft Anti-Malware with Online Armor, and few more what was so much for system so it needed to be cleaned-registry was full with rubbish.
After all now with my clean system I will use AIS with Google Chrome 9.0.570.1 SANDBOXED to keep system without new trash and in good condition. This solution is the best for my system.
Thanks...
