Can anybody help please

You might upload C:\Windows\Minidump\012118-17893-01.dmp to http://www.osronline.com/page.cfm?name=analyze. Their report might offer some help.

Or download “WhoCrashed Home Edition” from http://www.resplendence.com/whocrashed.
They analize the ‘.dmp’ files, too.

A bit late with a suggestion since this was probably already addressed by Avast with the VPS update released on Mon.

@bob

The post of trenuthseager concerms a W7 machine with a BSOD + ‘.dmp’ file, Simion offers help for analizing that file and I did the same.
Since when can a VPS update by Avast repair that problem?

Please realize, that your comments here are totally off-topic!

For quite some time, a VPS update has been able do a lot more than just update the virus data base.
