Well sometime I experience the same slowing, When I play a 360p or 480p everything works smooth, but when I want to play a 720p then the fun begin, avast is constantly wearing cpu 15-20%, when I play a lower quality avast doesn’t wear the cpu stay in 0-2%, and I have to mention that without avast I can play a 720p video on youtube without any slowdown . On some sites(the big ones), webshield tend to be aggressive on cpu wear. I saw that the next bild, promise performance improvements. Let’s see what brings.
Just updated from Avast free 7.0.1474 to 8.0.1483 from GUI. Everything went fine (Win Vista, 32 bit). Thanks, Avast.
Ditto to Greenflow’s experience. Auto-updated from v7 to latest v8.0.1483. Breeze. Thanks for great AV that loves working with Comodo firewall. 8)
i did this uninstalled avast used the uninstaller and re - installed from fresh and hope that fixs the web shield issue dropping the connection
Oh dear… 
Avast8 loaded fine. But found couldn’t access gmail or virginmedia emails in Windows Live Mail. Obeyed Avast’s nag screen to delete SSL entries in Mail Shield and started SSL in WLM and changed ports in each email profile to 465 and 995. Could only get WLM to work randomly. Rebooted and got blue screens. Only way back was to image restore and now back with Avast 7. :-\
Will wait for next update because I’m not the sharpest knife in the box. :-[
Hmm you could try the avast beta and see if your problem is fixed.
If not complete a bug report.
This update installed Google Chrome without asking! Bad form!
Well I always advice you to make custom install to avoid extra programs.
There was no choice to make a custom install, as it was “Update Program” from within Avast, not a new install. I hope Avast doesn’t begin to suck, as companies often do when management changes from engineering leadership to marketing leadership. (e.g. when Apple fired Jobs, and now Spotify)

It seems that this update has issues with the webshield. Internet connection is inconsistent. I can only access facebook and twitter in chrome. I have to disable webshield to go to other websites including this forum.
avast 8 1483 web shield slow down browsing at Win8, sometimes cause page cannot display due to timeout.
Sorry to be a pain, but yet AGAIN, my paid for (two years - £44.99!), my Avast Anti Virus icon has a cross on it and it says my system is UNSECURED. I’ve e-mailed the Avast Support Team, but they’ve not yet got back to me. Can anyone offer any advice, please? Thank-you.
Repair avast!:
- Control Panel → Add/Remove programs → avast!
- Click on ‘Repair’.
- Follow instructions.
- Reboot.
I’ve tried that, Asyn, no Repair button to be seen! Only Change and Remove. Can you further advise me, please?
After you click on uninstall you will then be presented with another screen where you can choose the option of repair.
Thank-you, Craig. However, it won’t let me do that and a Repair button is nowhere to be seen!
Download and save the removal tool http://www.avast.com/uninstall-utility and a fresh copy of avast http://www.avast.com/download-software.
It doesn’t sound like a normal removal is going to be possible so boot into safe mode and run the removal tool for all versions of avast you have ever installed and when completed boot back to normal mode and install your newly saved avast copy you downloaded earlier and install your license file from your email.
Far, far too technical for me, Craig! However, thank-you so much for your time and trouble - I’ve e-mailed Avast and await their reply. I am a complete geek when it comes to technical stuff. Once again, many thanks for your kindness.
It’s a fairly simple process, to boot to safe mode keep tapping f8 while starting the computer then navigate to where you downloaded the removal to and click to run, from the drop down tab choose the version of avast you have installed and ok it to remove and when completed restart the system and install the new avast copy you saved ( hopefully that makes it more understandable )
