Latest Avast Free Antivirus 17.8.3218 (build 17.8.3705.0) blocks mouse and keyboard input using TeamViewer and other remote access programs on a remote Vista PC when you open the Avast Free Antivirus program on the remote PC (to try and disable shields to install other programs, for instance).  Sending "Ctrl-Alt-Del" and running Task Manager gets me out.  Tried it on a couple of Vista PC's.  Work-around is to disable Self Defense Module while at the Vista PC (not a good option and cannot be done remotely).  Seems to work properly on Windows 10 PC's.

Avast, please fix this bug.  Is there a way to report it to Avast?  Are there any other work-arounds?

having same issue on Windows 7 Ultimate 64 bit and Windows 10 Pro 64 bit, when connecting using a remote client eg: TeamViewer or VNC as soon as I try to open any Avast screen I loose all mouse and keyboard control... I discovered unchecking the box labeled 'Enable Hardware-assisted virtualization' in the troubleshooting tab and rebooting solved the problem for now, strange but it does not happen on all the machines I help with, had 2 identical machines (win 10 pro) and only one exhibits the problem?
It appears there is a bug in this new release 17.8.2318 (3705)

So which is better...or worse?  Disabling the Self Defense Module or disabling the Enable Hardware-Assisted Virtualization?

That's a big issue!
How can we manage remotely user's pc if we cannot manage antivirus?
If so we have to change Antivirus! >:( >:( >:(

I tested it.
The issue is all about x86 systems! x64 are issue free.

Disabling the Self Defense Module is the only way to bypass the issue.

I can see it's been reported. It happens on 32 and 64 bit Windows Versions.

Sorry about this bug, it is caused by latest changes in self-defense, because of reported self-defense bypass using automatization SW using user input emulation. Will be fixed ASAP.

I use TightVNC and Splashtop and they also both get blocked when opening Avast Antivirus. I found this when Avast displayed a popup. It wasn't letting me click on anything until the popup disappeared.

This reared its ugly today on me!  I have put EVERYONE on AVAST Premiere.  I have to be able to run remote scans, etc..

As soon as I click on Avast and the User Interface pops up, I lose control.   That is not acceptable.

I dealt with the loss of the remote control module built into Avast Premier.  Now I use Teamviewer for all my clients.

I see a moderator said it will be dealt with asap.  I sure hope so.

Never judge a book by it's cover. :) He's an Avast employee and is certainly not kidding.
