Hi,
I’m a avast! v4.1 Home Ed user, running on Win XP. I have the same problem as well. I’m using Build - 4.1.501, VPS at 15Nov2004 v0447-0.

The avast program has not been able to do the automatic updates since a few months ago.

I get a Red System Message box :
“An error has occurred while attempting to update! Click here for more information …”

"Information about current update:
Last encountered error: Cannot connect to download12.avast.com (67.19.134.114:80).

Total time: 8:07"

When I execute the VPS file which I manually downloaded, I get this error message :
"Can’t install VPS update. Please, report following errorcodes:
SI:0x00000005
ST:0x00000005
LE:0x00000000.
"

Please help. Thanks.
