Avast 2015 (10.3.2225) kills Office 2013

You’re welcome. I did the same - original link was http://public.avast.com/~havel/2218/avast_free_antivirus_setup.exe and I changed it to pro. I hope Avast will repair it soon…

Hi guys,

can you provide me ID of your support packages?

This could be helpful for us in this situation. We’ll check the situation in detail.

Please into the PM or directly to the my email - radil@avast.com.

Thanks a lot.

I also met the same problem. I sent 2 weeks ago AVAST all information and error codes without answer… >:(
Right now I have had to restore my computer with an older backup (Ghost) and I locked the Avast software update (libraries can be updated)

Best regards

Strange, I use office 2013 on almost a daily basis. Currently on Windows 10 and have no problems at all ???
Also had no problems while on Windows 8.1.

Thanks for letting me know. I was just about to buy an avast! Pro license but this has turned me away

Letting you know that I have NO problems certainly isn’t a reason not to get Avast :slight_smile:

Perhaps promising. :slight_smile:

I too have experienced 10.3.2225 killing Office 2013.

Windows 7 Pro 64-bit
Newly installed Office 2013

Just finished uploading an Avast support file

The problem was addressed in the latest beta available at:
https://forum.avast.com/index.php?topic=175753.0

I have Program version 10.3.2225 and when I open Office 2013 I get the error

The application was unable to start correctly (0xc0000005). Click OK to close the application

I uninstalled and reinstalled Office, still the same issue. Uninstalled Avast (while Office still installed) and it opened fine. Very frustrating having to uninstall and reinstall Avast whenever I need to use Office.

I’m on Windows 7 64-bit also

Read Bob’s reply prior to your own, the issue has been addressed in the latest beta version.

Yes I had read that, but I wasn’t able to download the beta version.
And when it finally went through Avast came up saying it was a virus, so gg.

Absolutely livid that 3 weeks, a new SSD and a Windows 10 license only to find that this is a known issue that has not been shared with end-users for a critical application!

Sure, mea culpa for not considering that this product might have been a root cause and actively searching these forums for solutions but I appear to be overly trusting?..

Anyway, I can confirm the exact same issues reported by everyone else…

Windows 7 and 10 64bit all act in exactly the same way. What confuses things is that you find yourself trying the myriad of other solutions for 2013 such as disabling graphics hardware acceleration, recreating profiles, etc… And some of them work briefly here and there, then they don’t…

Oh and disabling Avast does not resolve the issue as Avast is quietly continuing to block/break things despite being told not to. That’s an interesting “feature”

The suggestion to update to the beta seemed like a good idea but with all the other issues like Macrium reflect conflicts, etc… that seems a little counter intuitive… For now I’m back to Win defender and applying a lot of common sense when clicking anything.

In all seriousness, Avast staff… You need to be highlighting this as a known issue and letting your customer base know… Not waiting for more p*ssed off end-users to find out the hard way… Waiting 2-3 weeks with no notice except this forum post is just poor communication and won’t do your product rep’ any favours.

For now Avast is off my systems and I doubt I’ll be reinstalling without a bit note to test everything 15 times before I update my main systems.

To be fair, only some user had a conflict with Avast and Office 2013.
I was one of those that never had a problem. I didn’t need the update to solve any Office 2013 problem. :slight_smile:

I can confirm there was a compatibility issue between Avast and Office 365 on 64-bit OSes. I couldn’t reproduce it on my own computer, but we got some memory dumps and we fixed this problem. (28/6/2015) – the fix is probably also included in Avast 2015 R4 Beta (https://forum.avast.com/index.php?topic=175753.0).

I have also been experiencing this issue and trying to troubleshoot the last several weeks. I’ve reinstalled office multiple times, disabled windows firewall and avast with no effect. Could this also be why my Adobe Creative Cloud apps can’t communicate with Quicktime? because that started about the same time too! They use TCP to work with Quicktime. I also submitted a support ticket.

Posting that support ticket would help for us to alert the Moderators. :slight_smile:

First I heard of Macrium problems…can someone post the thread link ?
I did a search and could not find.

I think he was referring to this topic and as you can see, it turned out to be a Bluetooth mouse problem:

Just to add my experience with this.

Updated Avast 1 week ago to latest version as it was asking me to, a day later noticed that when I start PC Microsoft OneNote tells me its crashed.
Can’t open any Microsoft Office 2013 applications as they error and crash.

I had some success getting only 1 Office application to open, if I stopped all Avast services, I could open OneNote 2013 sometimes, but no other Office apps like Excel or Word.

I re-installed Office after removing it and no change, my PC is fresh installed a month ago and doesn’t have much else running.

Now I have Office2013 apps all working, but only as I uninstalled Avast. Shame as it was best anti-virus application I had used.
