If you do a Google search on how to fix this problem you will find dozens of different approaches on how to access the registry of your computer from another computer and modify the damaged entries and get it back working again.
I am attaching a pdf file from one of the dozens of step by step tutorials. There are some great ones posted right here in EE on how to do it.
This problem is the typical "remainder" effects of the Win32/Virut virus that has become "epidemic" lately.
As always (this is just my opinion and has generated a lot of controversy) I suggest to people that no matter how well you remove a malware infestation, the affected machine will always eventually come up eventually with unexplained problems as the result of the very aggressive way in which anti-malware applications need to operate to remove the usually multiple and compounded infestations found mostly because some of the popups are to other websites that are themselves ultra-infected.
It is very typical... when you notice that your computer has one infection and you scan it, it turns out that it's not one malware but sometimes hundreds of them compounding the damage.
As far as I'm concerned (unless I am trying to learn something) my customers are better served (both in quality as well as financially) with making a backup of their data and allowing me to do a clean install.
I have timed this with two of my best techs, with similar computers and similar infections and it takes the better part of 2 hours to clean up a computer, remove all the junk in the registry, reinstall the antivirus and antimalware software, defrag it, tweak it, etc.. and still, despite their best efforts, sometimes the machine takes a nose-dive and they end up having to do a clean install anyway.
A clean install gives you the chance of having back the computer as fast as it was the day you bought it. It also gives you the chance of reinstalling you preferred applications in an orderly fashion and to defrag it as you go to keep the applications that usually become fragmented at the end and the ones that don't at the beginning of the drive. It eliminates all the leftovers from previous installs and uninstalls of software you now know you don't like or don't need.
I just can't even begin to tell you all the suffering and frustration that you will have to endure after doing what you think was a successful virus/malware removal and then a week from now you decide to install a printer or do an update and everything comes crashing down for no apparent reason....
Now, this said, read the attached document, get it to boot and once it boots, you can follow Mike_Carroll's advice of running MalwareBytes Anti Malware
This is a step by step as you asked:
1.Go into Safe Mode with networking by pressing F8 while booting your computer.
2.Then go to this website and download this program: MalwareBytes Anti Malware:
http://www.malwarebytes.org/mbam.php3.Before download..Important: Rename MalwareBytes before saving its files to the desktop as malware can recognize the name and block it unless renamed.
4.While still in Safe Mode, Go to Start-Run and type: Msconfig
5.Once in the Msconfig application, go to the "Services Tab" and select:"hide all Microsoft services" select the remaining and disable".
6.Then go to the Startup Tab and disable ALL entries there as well. Close the window. You will get a prompt to Reboot..allow it.
7.After the system boots go into NORMAL MODE.......it will give you a warning regarding the changes made by msconfig: Select "do not warn me again".
8. Now you can run the anti-Malware application your renamed and saved on your desktop above.
9.If viruses, spyware, malware, etc. are found allow the program to clean them.
After this you can also download: Hitman Pro 3.5 from
http://www.surfright.nl/en/hitmanpro to check for Rootkits...
Lastly, just to make sure that all your critical operating system files are not missing or damaged, from the Start-Run: type cmd and press enter.
From the command prompt type:
SFC /scannow (notice the space between the C and the /
you will need to have handy a Windows OS disk in case it asks you to insert it. If it doesn't find anything missing, it will not give you much feedback so don't be alarmed if you do not get any.
I hope this helps you... Keep us posted on your progress.
