"Slowed XP by adding entries to hosts file"
(10 filler chars)
Spybot grew C:\WINDOWS\SYSTEM32\DRIVERS\ETC\HOSTS from 1KB to 450KB with additional entries, causing svchost.exe to occupy CPU for many seconds at a time when loading some web pages. Found problem with Process Explorer, and solution at *****/1Oznne .
