Avast causing PC to lockup
« on: January 28, 2013, 04:25:25 PM »
We have over 200 Dell PC's in our company all using Avast Business Protection 6.0.1373. All running Windows 7 professional working fine.

We have just bought 15 Dell Pression T1650 PCs that all lockup roughly twice a week both while in use and idle.
When we uninstalled avast the PC's never lockup.

Has anyone else heard of this before or any suggestion on a fix.

Hello,

Most of the laptops come with preinstalled av software.
It is worth checking if there is another antivirus software running on all these PCs.

Cheers

What is the version of Windows that you install on these PCs?
When the lock-up occurs? During sleep or during normal work?
Do you have any scheduled scans running when the issue occurs?

We are running Windows 7 Professional on all PCs. The lock-ups occur both when idle and during normal work. Most of the time its during work but I guess thats always the case as they are only idle for an hour while people are on lunch.

There are no scheduled scans running at the time of the issues. But it is always running the Real-time scan.

As a data point - do you use DFS replicated file shares?

We have same problem too on Windows XP Home PCs. I just deinstalled Avast on 2 PCs and they working fine: no lockups, no block after logon.

Hi nannunannu,

We dont use DFS. Its a really basic setup. Clean install of Windows. We dont customize (Tweak) Windows at all and it's a simple network setup.

Did you check the event logs in Event Viewer?

Yer, checked event logs and it doesn't log anything out. The PCs never have a BSOD they just all lock up and we have to hard reboot them.
