Found a serious issue after updating to the latest issue this morning. My pc virtually stopped performing. I was unable to get program updates (SuperAntiSpyware). Trying to update only produced errors which has “never” happened before. My Yahoo home page would not finish loading (my bookmarks and other content would not load). I couldn’t get my bank homepage to finish loading and I couldn’t even get a simple Google bookmark to NHL box scores to finish loading. After numerous attempts I uninstalled Avast with the uninstall tool and then went back to a previous version (2014.9.0.2007). Now “everything” that I had problems with went away. I will stay with my working version until I hear that the latest version has been repaired. Oh yes, I also tested by turning off the web shield before I reverted and everything worked properly, pages would load and I could update.

Updating from 2007 it would have been better to do an complete uninstall and then install the latest version.

I wanted to go with something I knew from experience that works well. This way I can see if anybody else is having problems with the newer version? Besides the 2007 version isn’t that old, it just came out last month on Nov 11 so I’m not missing out on very much.

You actually are. Quite a few enhancements have been added since the version you’re currently using.

Well, Bob and Para-Noid, so far the new changes are not going very well. Especially with the new version of Web Shield. It doesn’t work very well with Firefox. Run without Web shield and things are ok, with Web shield and nothing will finish loading. It is no sense in operation a program without the Web shield activated. I see where many are having problems with this version. There is something very wrong within it. Somebody has to “Please fix” this version.

I did ‘CLean Installs’ on both OS’s and am not experiencing any of the issues I’m reading about.
Just saying.

You have access to an earlier version!! Is there a link? My browsers are locking like nuts after updating to this version and techs at Avast have cleaned my computer and uninstalled and installed it and it is still locking up. Sites like youtube won’t play video after 5-10 seconds or the browser just whirls and whirls its green or grey circle.
Where can I get an earlier version until they fix this!!

Please stick with one post. Posting in several places only confuses things and makes helping harder.

From ZDenek (avast team):
Hallo, we have discovered an issue in new WebShield implementation. This is probably reason of your problems. We are preparing fix for that.
Meanwhile you can try to switch to old WebShield implementation. To do that, please
Go to C:\programdata\avast software\avast directory
Find the WebShield.ini, file and add following lines:
[General]
UseStreamFilter=0
Now restart „avast! Antivirus“ service, or reboot.

Thanks. Of course I don’t want to attempt this because I am in no way tech savvy so I will wait until my escallation issue tech calls me and give him this information in case he doesn’t know.
Thanks.

Just so you know, you are dealing with third party support. Don’t let them try to sell you a service contract!
