Based on a CNET recommendation I pulled AVG Anti-Virus off my laptop and replaced it, and ZoneAlarm, with the free Comodo Suite. The PC now boots more quickly and runs faster. I don't know if it's due to both anti-virus and firewall benefiting from "one" application, or whether they run more efficiently, or whether the new apps aren't doing as much to protect me...I dunno...but whatever the case, I am happy (perhaps ignorantly so...dunno). I just did this today, so the jury's still out on the change's effectiveness. Here's hoping. All I know is the laptop just became emminently more usable again.
