Title: Slow, Slow, Slow
Post by: RupertNeve on March 17, 2013, 08:26:23 PM
I have been using Avast with very great success - until updating to version 8. Now my system is sluggish, and internet access/browser performance is very slow.

My connection speed before the update was ca 20-23Mbps. After the upgrade, it regularly clocks in at 8-10Mbps.

As a test, I uninstalled Avast. General performance was very crisp and speedy. I checked my connection speed at it was ca 28Mbps. I then tried MS Essentials. That clocked in ca 18-2o Mbps.

Not being entirely confident with MS (again, Avast has served me very well) I reinstalled Avast 8.  Once again, poor performance and slow connection speed.

As was the case with v6 and v7, I selected the default installation initially. The 2nd install I chose minimal. Same result: crippling performance.

Any ideas??

I agree with you, my internet speed becomes very slow when I install Avast, although I use Pro version with no firewall, "website not responding" appears very frequently.

I use Windows 8 x64 with Avast Pro 8.

Same here with an new install on a new computer. When I start the computer and check the download speed the speet is 1-2 Mbps. As a solution I turn off the shields for 10 minutes and check the speed again 30-35 Mbps and turn the shields back on. As a result the internet speed stays at 30-35 Mbps.

Is avast working on a solution for this?

I have the exact same problem. Is there a permanent solution to this problem?
