I too experienced issues with the recent update, except in my case, it affected Chrome and Internet Explorer.

I solved the issue by doing the following:

1) Uninstall Avast
2) Boot into Safe Mode and Run the Avast Remove Tool.
3) Install Avast
4) Boot into Safe Mode and navigate to your Avast install directory. Find the file named snxhk.dll and DELETE it.  Empty your Trash and Reboot.
5) Open Avast and disable Auto Update. I set mine to notify me when an update is available.

This method worked on my PC running Windows 7 Professional 64-bit.  I can now use Chrome, IE or any other browser without issue.

Hope this helps.

1, 2, 3) not needed at all.
4) No need to delete it as has been explained, rename it.
5) avast can and will still install updates through micro fixes.

OK, then riddle me this Batman, what do you do if you have both snxhk.dll AND snxhk64.dll on your system as was my case?!

5) avast can and will still install updates through micro fixes.

Yes and wouldn't you know, as soon as I let it update, it dropped snxhk.dll back into the program directory and made Chrome shit the bed again.  Better IMHO to disable Auto Update then continue to be Avast's guinea pig, but you do you bro.

Vapor, can you please try to disable self-protection (UI -> Troubleshooting), rename "snxhk.dll" / "snxhk64.dll" and run your web browser again if it helps? Thanks.

Your screenshot would appear to indicate the self-defence module is still enabled. 

Why would you not disable the self-defence module temporarily, it takes less than a minute and then you should be able to do as suggested.  Now you are left with waiting for the fix when delivered an a micro update.
