Hi, I’m new with Avast, but not with computers (my job).
I installed the newest download on a Windows NT4 Workstation SP6 System, without the bootcheck option. There is no other av-tool running, but Zonealarm firewall is. This should be fine, I thought. After rebooting, my system wouldn’t allow any call to executable programs anymore, only the explorer opened, as far as I hadn’t clicked anything else before. Also neither the Avast-GUI itself, the service control manager, the task manager, nor any other helpful tool opened (the mouse went to hourglas and the system was deadlocked), I wasn’t even able to only stop the thing for uninstalling or simply deleting any main files of it. The NT-recovery console didn’t offer much help, as access to the programs folder is denied.
It cost me a night of criminological legwork to just remove the tool, accessible file by file, until I could get rid of it as a whole.
Maybe I did something wrong, bur really, I just installed it straightforward, as one would expect to do so and rebooted.
As the commentaries of other users sound fine, I would still like to use it myself, but it doesn’t seem to work on NT4.
I think avast should work into NT4 systems…
Blocking of the exe files is strange, unless, you changed anything into the Block Behavior settings of Standard Shield, but you don’t seem even to get a first correct boot… :
Which version of ZA are you using?
Regardless this bad start, welcome to avast.
Thanks for answering,
I’m using a licensed ZA Pro 4.0.123, since later versions had bad sideeffects, as NT is no longer really supported. Before I had a Norton Corporate AV version, which expired, but worked fine.
Problem seems to be: every exe seems blocked only after login, even from batch files in autostart, whereas not the batch file itself. It seems like just the second significant call (and all subsequent) is blocked. Anyway, I fear trying again because of the pain of dismantling the blockage.
I almost sure this is the problem.
Trash left behind by Norton should be conflicting…
Maybe in Symantec site you’ll find other stronger (standalone) application to remove it.
You can only try again after we’re sure Norton has gone.
Better if you can uninstall ZA for a while, install avast and install ZA again after.
