Well brother you can easily remove the antivirus system pro without using Internet by just manually removing it...........
For this you just need to follow the steps below:
Step 1
Remove the pop-up advertisements temporarily and end bad processes:
Push Ctrl + Alt + Delete at the same time
Choose "Task Manager" in the Windows Security menu
Click on the "Processes" Tab
Search for the following processes: Antivirussystempro.exe, uninstall.exe (if constantly running), and sysguard.exe
Disable these processes by clicking the "end process" button
Step 2
Conduct a search on your computer for Antivirus System PRO files:
Go to the start menu and click the search button
Make sure you search "All files and folders" in the "Local Hard Drive" or C Drive
Type "Antivirus System PRO" in the search box and search for all of these files including:
c:\WINDOWS\system32\iehelper.dll
%ProgramFiles%\Antivirus System PRO\conf.cfg
%ProgramFiles%\Antivirus System PRO\mbase.vdb
%ProgramFiles%\Antivirus System PRO\quarantine.vdb
%ProgramFiles%\Antivirus System PRO\queue.vdb
If none of these files appear, then you may have to search for each file individually.
Search and delete the following folder:
%ProgramFiles%\Antivirus System PRO\
Step 3
Create a backup file of your entire registry. One way to do this is to generate a system restoration point:
Click Start, All Programs, Accessories, System Tools, System Restore
Choose "Create a restore point" and click the Next button
Type in a name to recognize the restore point and click "Create"
Step 4
Remove files from the registry:
Click Start, Run, and type "regedit" in the available field.
Hit the Enter key, or click "OK", and the registry editor should appear
Select Edit, Find, and search for the following:
HKEY_LOCAL_MACHINE\SOFTWARE\Antivirus System PRO
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Antivirus System PRO
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run “Antivirus System PRO”
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad “ieModule”
HKEY_CURRENT_USER\Software\AvScan
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run “system tool”
HKEY_CLASSES_ROOT\CLSID\{BAD4551D-9B24-42cb-9BCD-818CA2DA7B63}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{BAD4551D-9B24-42cb-9BCD-818CA2DA7B63}
If you locate any of these files, right-click the file and select "Modify" and "Delete"
Step 5
Remove DLL files for those who have c:\WINDOWS\system32\iehelper.dll in their processes:
Go to Start, Run, type "cmd", and click "OK"
Type "cd", enter a SPACE, and type c:\WINDOWS\system32\iehelper.dll
Once the file is located, type regsvr32 /u iehelper.dll and hit "Enter"
Step 6
Search the local hard drive once more for "Antivirus System PRO" and "SYSGUARD" separately to make sure all of these files are deleted.
Step 7
Restart the computer. If no pop-ups appear after restarting the computer then the malicious software should not be on your system. Double check to make sure the Antivirus System PRO software has not returned.
Step 8
Repair any damages that may have occurred from the malicious software or deletion. Check to see if your desktop icons and homepage have been changed or moved.
