I have really appreciated the people here but I am leaving avast. The two main reasons are:
-Avast hogged CPU (up to 80%)
-Scheduled scan never works and avast admins never helped me with this issue
I will be switching to AVG now. I might come back to see how avast is doing in 2014 or earlier.
Anyways, goodbye everyone. I will miss you all. Thank you avast for protecting me from viruses.
Warm regards,
websave
tried latest version ?
http://forum.avast.com/index.php?topic=123563.0
remove old with this. http://www.avast.com/uninstall-utility
Yes
Thank you for the advice, Pondus.
While I still use and recommend Avast I do think it is getting bloated. I stopped using AVG years ago because it got bloated and slowed my computer to a crawl. Avast seems to be headed in the same direction. When I boot up my computer and can’t use it for several minutes while Avast does it’s thing I do get frustrated. I have even changed the setting to load Avast after my system boots but it makes no difference. The older versions of Avast never did this. And I don’t have a slow computer with tons of items starting in the back round upon boot up. Just my observations and opinions. I’d like a lite version of Avast and not the bloated Avast that it has become.
I know right? Avast says it’s really light but it is becoming bloat-ware.

Something must be off in your rig. Avast! scored pretty low for performance impact in systems according to the latest AV test done in April, and much much better than AVG see image

BTW are you running Comodo 6 ?
I’ve installed Avast on an older system, circa 2007, 2GB DDR 1, AMD 64 X2 4200 dual core.
When I installed Avast I did a custom install, deselected the IM and p2p shields and all the “extras” in the middle column.
I don’t want any of it. Startup is reasonable in XP SP3, I would say there is about a minute of extra activity,
probably Avast searching/downloading and activating updated patterns.
Beyond that, I find the performance impact mostly unobtrusive; it behaves better than MSE (in my experience)
in terms of its general impact. (That may be not saying much).
Why did you ask about Comodo 6?
Yes I am running Comodo 6. It did not work well with AVG…(Computer went really slow and would not log in). I guess I’ll be using avast again.
Btw,if you need any help forum is always open ;D
Thank you. 
I’m going to run some tests with avast. First I’ll do a clean uninstall of everything then get avast again. If everything works fine, I suspect it is COMODO. Even though I have had problems with avast! it was hard to leave. I am still loyal to avast! 
By Comodo do you mean the firewall or the firewall “and” the anti-virus? ???
You shouldn’t have two resident a/v’s at the same time http://www.bleepingcomputer.com/forums/t/260844/two-anti-virus/#entry1441638
To install just the firewall follow these instructions to the letter http://www.knightwithapc.com/2011/11/download-comodo-firewall/
Just COMODO firewall
What is your OS? What other security software do you have now or ever had? If uninstalled, how was it uninstalled? ???
Ummmmmmmmmmm. Comodo just had an update to correct cpu usage. Also with Windows 7 or 8 you no longer need a 3rd party firewall. Dont blame Avast. I have installed Avast with Windows Firewall on hundreds of pc’s including my own with no issues at all. As in matter of fact it was a list of 200+ bugs. Have you used something like Process Explorer to assure exactly what process is consuming your CPU? Can you show us a screen shot of Avast eating up your CPU? These are the problems which occur when people add extra layers of security. Did you excluded ALL the Comodo processes from Avast? Did you excluded the Avast processes from Comodo? Also Avast has a BB which can conflict with D+.

Couple of years ago, much the same security setup as you. Avast! a/v free, COMODO firewall free. I gave up on COMODO as I was running the system (see sigs below) below and it would actually freeze/hang for several seconds whenever off-line or when installing new software; also even when online. D + was the culprit, and the automatic checking to the cloud always took some time to complete. Once COMODO was removed, (and D + along with it) lagging/hang/freeze was no more. Solution was to use another HIPS capable firewall such as Online Armor.
Running D + just got to be too much, so COMODO went out the door. Running COMODO without D + was not an option, otherwise what was the point?
I suspect that on some older machines it just does not work as well as it should, even if the machine exceeds minimum requirements as this one does.
Thank you for the info. Man avast! free is so great, I’ll use avast all my life
