I was unable to perform the previous steps provided by you as my laptop just went down the hill from thr on and I had to format and restore it back to factory setting.
If I understand correctly this was the machine we were working on, if so fair play and thank you for informing myself.
Now I have two desktops at home on which I connected my external Hard Disk Drive and scanned it using Bullguard software. I had a number of viruses which I cleaned by deleting all of them. However when I detached my Hard Drive and connected it back Bullguard again detected viruses and quarantined them. Now I do not know how to get rid of these viruses. The System Volume is affected by Win32.Virtob.Gen.12 & Gen.Trojan.Heur.GM.0000026180.
This is not good news at all I'm afraid one of the infections is a variation of a polymorphic, memory-resident file-infector.
I am in deep troube trying to clean up all the viruses and my work is badly affected because of this (3 days of unproductivity). I sincerely request you to help me at the earliest.
These are business related machines even though this forum and I myself have a policy about not providing assistance for such it is all a moot point.Next
One or more of the identified infections is a severe Polymorphic File Infector
This allows hackers to remotely control your computer, steal critical system information and Download and Execute files
I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.
Unfortunately no attempt could be made to clean this machine, it could never be considered to be truly clean, secure, or trustworthy. We could not say definitively that unknown and unseen malware will have been removed, nor will your system be restored to its pre-infection state. We cannot remedy unknown changes the malware may likely have made in order to allow itself access, nor can we repair the damage it may possibly have caused to vital system files. Additionally, it is quite possible that changes made to the system by the malware may impact negatively on your computer during the removal process. In short, your system may never regain its former stability or its full functionality without a reformat. Therefore, your best and only course of action is a reformat and reinstallation of the Windows operating system, and that is the course we strongly recommend.
I also recommend you format the external Hard-Drive and if you use a Router, reset it and apply a new Admin' password.

I suggest you to start backup all of your valuable data/documents/pictures/movies/songs/etc..
Do NOT backup any applications/installers and Do NOT backup any .exe/.scr/.htm/.html/.xml/.zip/.rar files...
This is because these files may be infected as well. If you back them up and replace them afterwards, it will infect your computer again.
Should you have any questions, please feel free to ask.
