Crippleware
for a program that has greater functionality and effectiveness than many of the paid for versions and the Home version is Free, this throw away comment is unwarranted.
whocares is totally right, we need more information in order to be able to help
I have the assumption that this is more likely to be down to the user settings, than any form of crippleware.
If AVG was so great why would you want to change? I used AVG for a long time and Avast, in the short time I have been using it, beats AVG hands down. On my first scan after installation (after reboot) it found two viruses that had lain dormant for months without dectection by AVG.
Speed wise Avast is easily as quick (on my machine) as AVG and I get better protection.
Speed Vs Efectiveness/Thoroughness is always a trade off, if I want to do a thorough scan, including archive files I do it when I will not be using the computer for a short time, not when I am waiting to do some work on it.
