zone alarm is garbage it takes a lot of RAM…i am running 3GB ram…
get comodo it is the best! 8)
True for the new versions of ZA.
4.5 is the best 
Tried comodo, didn’t like it.
Tried disabling ZA btw, didn’t help.
So avast is messing up somewere else 
And why does it work after uninstalling, cleaning and reinstalling?
That can only point to something not done right in the upgrade process.
Disabling won’t actually make a great deal of difference as the low level drivers will still be running, some considerable time ago didn’t ZA block all internet access when disabled ???
The likelihood that a clean install of avast resolves issues in the ZA Program control, that was a major issue with ZA getting digital amnesia, e.g. even though a program had permission to connect it was blocked. Deleting the avast entries in ZA program control is the first action I would try if a program/process was blocked. This forces ZA to either Ask or Allow the new entry, depending on your settings.
Why manual clean up? Isn’t the specific removal utility for Avast enough for registry?
I know that some folders may be left behind, but I don’t know about registry entries leftovers after http://www.avast.com/uninstall-utility when it is under Windows Safe Mode.
Deleting the relevant firewall rules after an avast update is many times all what you need (but not always).

I do think there’s a bug in the Avast update/setup process that’s effecting some XP systems. My mom’s E-Machines with XP SP3 works perfectly but my Dell Dimension 2400 has had nothing but problems. I finally did get Avast to work pretty good, but still every couple of days when I update definitions it looks like it’s working normally, then when it’s about to finish it shows an error message saying setup was unable to finish. In the Maintenance window it shows the correct definition version but in the Summary window it says it’s out-of-date and displays red. When I reboot the Avast service won’t start, manually or otherwise. I have to do a repair then reboot and it works. I have System Restore and Windows Firewall disabled and no other security software whatsoever. This is a secondary computer and luckily it doesn’t do it every time so it’s more of an inconvenience than anything.
I have not yet had even ONE successful program upgrade of AVAST Pro on any of almost a dozen XP pro machines after AVAST was initially installed - this includes the current version as well as the previous three versions of AVAST. The program upgrade has crapped out the systems in each and every machine in a variety of ways - usually resulting in the inability to fully boot into Windows. Fortunately, each machine that I support had an image made of the active drive BEFORE trying the upgrade and a successful restoration was done in under ten minutes on each machine. Yes - Zone Alarm Pro is installed on each machine but that is NOT the cause of the upgrade failure as I had the same bad results with AVAST on a newly installed XP Pro machine that I am setting up today. Zone Alarm had NOT even been installed yet as I decided to install AVAST first resulting in the same problems of Windows locking right after logging on. This XP Pro installation today had all of the Microsoft upgrades done BEFORE installing AVAST on this new installation. I restored the image and am now looking for an anti-virus alternative - other than Norton or McAfee, much to my chagrin. I liked the OLD AVAST as I NEVER had a problem with it.
Also, the ONLY way I can get AVAST installed anymore is to install it IMMEDIATELY after the Windows new or clean installation is completed - BEFORE updating Windows and before installing any other software.
Bad stuff, indeed!!!
Windows XP-SP3 hangs after latest Avast Update. Have to disable Avast before System can start.
Currently, Avast Free is disabled on all my PCs.
Never ever had I ever faced any problem with Avast Free, before. This is pretty bad! I have Avast Free installed on on all of my Family/Aged Relatives’ PCs. They are all going to be down now.
Avast: Please HELP URGENTLY!!!
In my case the latest Avast update broke internet connectivity. After the update, I could still connect to IRC and use various instant messengers, and https addresses would work, but regular http would not. Disabling Avast finally made the problems go away.
Win 7 Pro 64-bit, also running ZoneAlarm 10.1.065.000 - and removing ZA is not an option. If there’s an unresolved conflict, Avast is the one getting the boot.
I would regard my av as being more important than the Zone Alarm firewall myself, especially when there are far better firewalls out there ( Outpost, comodo, online armor, privatefirewall ) and also the addon programs for the windows firewall.
Zone Alarm has had repeated conflict’s not only with avast but numerus av’s for a long time, there are people that do seem to be able to get the two to play together nicely but they are few and far between imo.
Running 3 comps at home with XP pro Spk 3 and latest Avast. No problems here. None with ZA.

I would just like to state that after repeated problems with Avast updates on my Windows XP SP3 machine, I uninstalled Zone Alarm prior to the current Avast update and this time, I have had no problems at all. There must be some sort of conflict between the two, so if you want to keep Avast, I would recommend getting rid of ZA which is now well known for conflicting with many av’s. Your choice.
