AvastUI.exe - Application Error

Avast Free Antivirus / Premium Security
1

Folks,

A user that I support received a dialog box this morning:

“AvastUI.exe - Application Error - The instruction at 0x77182d24 referenced memory at 0x0d6d6f6e. The memory could not be written. Click OK to terminate the program”

The user clicked OK and seems to be running ok for now, but I’m not sure exactly what part of avast has been “terminated”.

O/S: Windows 7 Ultimate 32-bit. Avast Free.

The last time the user got this message was about a month or so ago when a bad signature file/engine update was released and a lot of false positives resulted (related to a FP in javascript files which quickly brought QuickBooks down). I had the user reboot and that’s when all hell broke loose with the FP reporting. Avast had the problem fixed within an hour or two with a corrected update.

This time, I’m not seeing any such situation being reported by the community.

Can you give me guidance on what to do next?

Thanks!

I’m seeing one other similar report by user this morning but I’m not sure if it’s related.

I performed system scan with HitMan Pro and Malwarebytes and neither found any malware on the system.

I tested Avast’s functioning by opening an EICAR test file and Avast caught it and blocked it, so the Avast engine appears to be ok.

Any thoughts as to what all this means?

I got the same last night - dialog box out of nowhere saying.

Application popup: AvastUI.exe - Application Error : The instruction at 0x778fe3c6 referenced memory at 0x0d72f599. The memory could not be read.

Click on OK to terminate the program

I checked with taskmanager & AvastUI.exe was still running!

Windows 7 64 bit.

ATM I am just curious & not overly concerned.
