Hi and welcome to G2G. We'll see what we can do. Do you have a USB drive and another working computer that you could download FRST on to?
If so please follow the instructions below. If you don't, let me know.
Step#1
1. From a working computer, please download Farbar Recovery Scan Tool and save it to a USB thumb drive.
Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.
2. Plug this USB thumb drive into your "sick" computer.
Step#2
1. Shut down your "sick" computer and leave it off for a good 10 seconds.
2. Power on your computer and then repeatedly tap the F8 key on your keyboard (about a second apart for each tap). This will open up the Advanced Boot Options screen which will look similar
to what is shown below.
3. At the above screen you will see a variety of options that can be used to boot Windows. Using the arrow keys on your keyboard, highlight the option labeled Repair Your Computer.
Once it is highlighted, click on the Enter key on your keyboard. Note: If you don't have a Repair Your Computer option please skip the rest of the steps in this section and go below to the next
section after step#14.
4. Select US as the keyboard language settings, and then click Next.
5. Select the operating system you want to repair, and then click Next.
6. Select your user account and click Next and you will be at the System Recovery Options menu showing the following options. Please use the arrow keys on your keyboard to select
Command Prompt and then hit Enter.
Startup Repair
System Restore
Windows Complete PC Restore
Windows Memory Diagnostic Tool
Command Prompt
7. In the command window type the word notepad and press Enter.
8. Notepad opens. Under the File menu select Open.
9. Select "Computer" and find out what your USB drive letter is and then close notepad.
10. In the command window type e:\frst (for x64 bit version type e:\frst64) and press Enter
Note: Replace letter e with the drive letter of your USB drive that you identified in step#9.
11. The tool will start to run.
12. When the tool opens click Yes to disclaimer.
13. Press Scan button.
14. It will make a log (FRST.txt) on the USB drive. Please plug in the USB drive into your working computer and copy and paste the contents of it into your reply.

Thank you for your help. Underneath please find the saved txt file. Maybe it would help, before your message I tried different antivirus recovery disks (kaspersky, norton, avg, etc) but upon booting from the usb the following message came up: missing bootmgr , restart: ctrl+alt+del. the only way I could go to the Repair computer list was through Win7 starter /same as installed on the sick laptop/. I even tried to fix with an XP but same missing bootmgr came up. When I went into DOS through the Win7 Starter usb, then tried sfc /scannow, answer was the system is under repair , restart computer and type again sfc - obviously it is not possible to do this due to the black screen.Also came up a message, cant remember how and what I did - it said: explorerframe.dll missing. I also tried to reconstruct bcd but same answer came back.All these happened before I got your message above. 1 more thing just remembered. In the last few years Windows task line regularily disappeared from the bottom, so I had to go to task manager, finding explorer.exe, swithc it off, then in run starting againg typing explorer.exe. Seemed for me some bug always ate it up. As you see I didnt use the laptop in the last month, if need more info then I can do a new scan for the last 3 months (as I remember there was an option for this in your program)
So here is the feedback from FRST:

Thanks for the detailed info. From this point forward, I'm going to request that you only perform the instructions that you are provided so that we don't do too many things at once and potentially cause a problem we can't fix.
- General Instructions -
- Please read all instructions and fixes thoroughly. Read the ENTIRE post BEFORE performing any steps so you understand all that needs to be done.
- I would advise printing any instructions for easy reference as some of the fixes may require you to boot in Safe mode. Access to these instructions may not be available in Safe Mode.
- Any fixes provided by myself are for this log file only and should not be used on any other systems.
- Do not run any other removal software or perform updates other than the ones I provide, as it will complicate the cleaning process.
- It's very likely that part of our cleanup will include emptying your recycle bin. If you use your recycle bin as an archive and do not wish this to be emptied, please let me know.
- It is also likely during our cleaning process that your internet browsing history will be removed. Your favorites will be untouched. If you don't want this to happen you need to let me know before running any steps so I can adjust my fixes accordingly.
- You have 4 days to reply to each post or the topic will be closed. You will be able to request that the topic be re-opened by sending me a PM (Personal Message) or PM a moderator.
- Please feel free to ask any questions, especially if you are having problems with my instructions.
- Save ALL Tools to your Desktop-
All tools that I have you download should be placed on the desktop unless otherwise stated. If you are familiar with how to save files to the desktop then you can skip this step.
Since you are continuing with this step then I assume you are unfamiliar with saving files to your desktop. As a result it's easiest if you configure your browser(s) to download any tools to the desktop by default. Please use the appropriate instructions below depending on the browser you are using.
Google Chrome - Click the "Customize and control Google Chrome" button in the upper right-corner of the browser. Choose Settings. at the bottom of the screen click the
"Show advanced settings..." link. Scroll down to find the Downloads section and click the Change... button. Select your desktop and click OK.
Mozilla Firefox - Click the "Open Menu" button in the upper right-corner of the browser. Choose Options. In the downloads section, click the Browse button, click on the Desktop folder
and the click the "Select Folder" button. Click OK to get out of the Options menu.
Internet Explorer - Click the Tools menu in the upper right-corner of the browser. Select View downloads. Select the Options link in the lower left of the window. Click Browse and
select the Desktop and then choose the Select Folder button. Click OK to get out of the download options screen and then click Close to get out of the View Downloads screen.
NOTE: IE8 Does not support changing download locations in this manner. You will need to download the tool(s) to the default folder, usually Downloads, then copy them to the desktop.
- Finally Before We Start-
Removing malware is a complicated multiple step process, Please stay with me until I have declared your system clean. I strongly recommend you backup your personal files and folders. Although rare, attempting to remove malware can render your machine unbootable or cause data loss. Having backups of your data is your responsibility. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
OK, let's perform our first fix.
Please follow the instructions below to perform a fix.
Note: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to the operating system
Download the Fix
1. From a working machine, please download the attached fixlist.txt.
2. Save it on the flash drive just as you did when you downloaded the Farbar Recovery Scan Tool.
3. Plug your flash drive into the infected machine
Run the Fix
1. Open up FRST from the USB drive as you did previously.
2. Click the Fix button just once and wait.
3. The tool will generate a log on the flashdrive (Fixlog.txt) please post it in your reply.

how this virus-malware could damaged my computer through this program?
Not exactly sure what you are asking. If you are asking how malware can get past an antivirus software the answer is fairly simply. Antivirus generally can only protect you against malware that it knows about. With well over 100 different ransomware strains that are out there and a ~800 percent increase in phishing emails from 2015 to 2016 antivirus is becoming more reactive than proactive. It's necessary to have but the most important first line of defense is you. We have all of our employees at work trained in Security Awareness which we found much more useful and had better results than relying on Antivirus alone.
Does your computer boot normally after the fix?

Thanks. At the command-prompt again, please type the following and hit enter.
chkdsk c: /R <---that's chkdsk followed by a space followed by c: followed by a space followed by /R
When it finishes, try rebooting your computer again and let me know the results.

Same black screen. So I downloaded fixshell.exe from prevx. It didnt fix, but, after running the fixer I checked in regedit the Shell Reg Sz. And now it is as it should be: explorer.exe. When restarting the computer the same black screen comes back. I also copied the entire C drive in DOS onto an external hdd and did a kaspersky virus scan from the healthy laptop. No viruses found on the C drive. I also rebuilt the bcd (saved the old one) in dos, didnt help. I know it was easier to reinstall winshite, but know I am crazy to find out what changes the Shell upon rebooting the system. Any idea?
Just did a startup repair with the OS , it says startup repair cannot repair this computer automatically.
started this for a try...
sfc /scannow /offbootdir=c:\ /offwindir=c:\Windows
Windows resource protection didnt find any intergity violations. Restarted in Safe Mode...nothing, still this black screen with cursor.
here we go: so fixshell.exe fixed the Shell to explorer.exe. Restart...black screen. Then opened again regedit and now Shell is cmd.exe /k start cmd.exe. So started the fixshell.exe and then checked again regedit/shell....the fixer overwrote it to explorer.exe.
As u might remember, I had this ongoing issue with explorer.exe, regularily the bottom tray disappeared. then I had to go to task manager, stop explorer and restart it in the run command. do you think it is the graphic driver? as I can use dos I didnt think about a damaged driver.
