Consider bad luck or whatever, the latest version on over the top installation , literally delays the desktop display at the restart and the Network gets jammed. So I uninstalled it , ran the AWS clear tool , once again installed 2014, to no avail and the similar symptoms prevailed. Hence repeated the whole process again and got back to 1489.
The developers need to do something on the XP compatibility.No issues with Win 7 however. Thoroughly disappointed…
Infact I had already made a post for the previous version http://forum.avast.com/index.php?topic=143352.msg1040180#msg1040180. Still it is not working here…
Latest version is working flawlessly for me on XP SP3.
Must be something on your system.
Perhaps it is time to do a thorough cleanup of your system by installing Windows from scratch.
Anybody who suggests reinstalling Windows as a solution should be sent to the naughty step.
Other versions of Avast had and still have no trouble with WinXP SP3 yet these problems with the new Avast version have been reported for months. There are more than enough people for even the most sceptical to have to admit that there is something wrong. What that is and why it is happening for some and not others is, apparently, still unclear.
The fact that no fix has been provided is IMHO suspicious. WinXP support from MS disappears in a few months’ time and MS are on a campaign to get us off XP (despite the fact over 35% of the world’s PCs are still using it). As time goes by there is less and less incentive for Avast to provide that fix particularly if there is a lot of work involved.
It is my belief that we XP users are being cut loose and there will never be a solution. Those on WinXP should simply stick with the last known fully functional version of Avast unless they have a full system backup available to recover should they get the sort of problems reported here.
So far I never have seen any version of avast failing on any cleanly and correctly installed XP-SP3 (and all other updates) system.
The same happened to me yesterday. A clean install fixed it, though.
Yeah, I guess I was lucky this time.
Ah, I forgot to mention that in addition to the avast! cleaner, I also run ccleaner for the registry part and had to manually delete some ghost device leftover.
As for all the loud fan boys. Unfortunately, there isn’t any proper moderation here in this support forum. Basically you have to just ignore them and some of their bad or harmful advices.
@Nagan
Had the same problem with my father’s laptop this afternoon. I tried a clean install, this time to no avail.
However, I also tried disabling the “hardware-assisted virtualization” in settings/troubleshooting. That worked, apparently.
Hope this suggestion might help you.
System Info:
Win XP Pro SP3
Avast! Free AV 9.0.2013
Online Armor Free 7.0.0.1866
Thanks everyone for the kind suggestions and replies. Anyway I have decided it will be 1489 for my XP SP3 system unless a developer is willing to take a look at why the modern versions are not working for XP.
Also it appears only a few with XP have no issues with latest AVAST.
As I said before, the latest version of avast is working flawlessly with XP-SP3 (and all other updates)
The problem is caused by what you already have installed (including remnants of things) on your system.
Well I’ll chime in here, as I also have no issues on xpSP3 with Avast Premier 2014 and have beta tested with this xp through all versions since version 4.
Also is working flawlessly on W8.1 64 Bit 
;D
But you’re both ignoring the fact that these aren’t, in most cases, new installs of Avast but program updates for people who have been using previous versions and updating Avast without such issues for, sometimes, many years too.
Blaming it on something else on the computer which, if true, most likely was there before yet not causing problems with those previous versions of Avast is a little desperate.
Revert to Avast 8 and greatly reduce the nuisance of the frequent emergency updates with Avast 9.
Cluster-Lizard,
no we are not. You are ignoring the fact that (almost all) the problems are caused by a conflict between avast and what already is installed.
It can be applications, (old) drivers, windows components, remnants of software etc. etc.
hake,
if you have nothing sensible to contribute… Please don’t post anything.
wow, Eddy, … getting a little agressive?
Just because it is conflicting with something doesn’t mean that it isn’t something the developers could be looking at.
In the past haven’t they often tried to identify and address conflicts?
@nagan Considering its a old XP desktop, I would try to Windows update to see if there are any updated drivers paying attention if there are any newer display and network drivers which are sometimes listed under “optional” updates.
If that fails and nobody at Avast or nobody in the forum capable of in depth troubleshooting steps up, I personally would just choose an alternative AV and move on.
As a thought how many different types of programmes can windows XP run. How many are still available for download
Sorry. :-[
A lot of assumptions in your statement, I don’t believe you are aware of process I use to Install and Uninstall software when testing, Updating or Reinstalling.
I simply stated I have not experienced any issues on xpSP3. I consider this is because the software is compatible with my OS configuration. 
I do not think any drivers could be a issue as a previous version is working properly. But still it is a possibility , which I may not find much to do about.
I might consider changing the AV as the last resort…
