The following message began to periodically appear on my monitor of late (in my translation from Russian into English):
"Efd.exe - Application mistake.
Instruction at "0x00021a7d" address has applied to memory at "0x00021a7d" address. The memory cannot be "read".
[Press] "OK" to close the application
[Press] "Cancel" to adjust the application"

I tried both buttons, but all was in vain and the reminder went on pestering me.

Yesterday I tried to find a solution to this problem through Google and was redirected to www.pc1news.com. I had the misfortune to download SpyHunter from the site. The software allegedly was designed to deal with the efd issue. I made a system recovery point before installing and running SpyHunter. As a result, although SpyHunter found and eliminated some malware from my home PC, I can neither access Internet from home, nor access the system recovery point the service is out of order.

What's to be done? I rely on your help.

Eliminate any virus in your system. If your Windows is Russian, use Anvir.net (http://www.anvir.net/) (do custom install without any Yandex addons). If things are too bad, use Process Explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx).

Restore system files, scanning with System File Checker (sfc.exe). Further reading (http://www.updatexp.com/scannow-sfc.html).

Reset TCP IP stack, howto here (http://www.petri.co.il/reinstall_tcp_ip_on_windows_xp.htm) and here (http://support.microsoft.com/kb/299357).

Good luck there and let us know how it went :piano:

Thanks, Artyom, for the recommendations and the links. Hope to be able to report from home within the next 55 hours.
BTW, it seems my modem went bust on its own (but at the same time as the computer broke down). (My God, what a character!)

With pleasure. What I also found extremely helpful is a TeamViewer program (http://www.teamviewer.com/index.aspx).
It allows remote connect to any computer and contol screen, mouse and keyboard, and resolve technical issues, make presentations, transfer files back and force. As long as your computer connects to the Internet, use TeamViewer and invite your trustworthy technical guys/colleague/friend/faamily member to help remotely. It even works between PC and Mac which I found amazing. Security is pretty good as sessions are protected with one-time passwords and also every action confirmation as an option. As soon as all issues are resolved or presentation is done, turn off TeamViewer and there is no acceess to your computer anymore.
