Sister, first I am really sorry for your problems. Lets do the following and take it from there. It will take some patience but I guess we can fix it. And I think your RAM is more than enough, no need to put any extra RAM.
Step 1
Download SecurityCheck from here:
http://www.bleepingcomputer.com/down...ycheck/dl/123/
Save it to your desktop.
Double-click SecurityCheck.exe and follow the instructions inside of the black box.
A Notepad window called Checkup.txt should automatically open.
Copy and paste that here or send that to me.
Step 2
Please run a free online scan with ESET Online Scanner by downloading it here:
http://www.eset.com/us/online-scanner/
Save it to your desktop.
Double-click esetsmartinstaller_enu.exe to execute the program.
Tick Yes, I accept the Terms of Use.
Click Start.
If this is your first time installing the scanner, allow the ActiveX Control to install.
Database download may take some time.
When done, make sure that the option "Remove found threats" is ticked under the "Advanced Settings", please put a check on the following options:
Scan for potentially unwanted applications
Enable Anti-Stealth Technology
Click Start.
Wait for the scan to finish.
Once it is finished, use Notepad to open the log file located at C:\Program Files\ESET\ESET Online Scanner\log.txt (32-bit) or C:\Program Files (x86)\ESET\ESET Online Scanner\log.txt (64-bit).
Copy and paste that log here or send that to me.
Step 3
Please download Malwarebytes' Anti-Malware . If you have done this previously, please do not disregard my instructions and repeat the process.
Double-click mbam-setup.exe to install the application.
Make sure a check mark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
If an update is found, it will download and install the latest version.
Once the program has loaded, select Perform Full Scan, then click Scan. The scan may take some time to finish, so please be patient.
When the scan is complete, click OK, then Show Results to view the results.
Make sure that everything is checked, and click Remove Selected.
When disinfection is completed, a log will open in Notepad and you may be prompted to restart. Restart if it tells you to.
The log is automatically saved by Malwarebytes' Anti-Malware and can be viewed by clicking the Logs tab in the interface.
Copy and paste that log here or send it to me.
I suggest you spend some time in doing this and then we can look into the problem
