Now i am quiet worry about this thing. How to avoid this virus and what are the tool available to remove this virus. And i also want to know how this virus spread.

First scan your pc with an antivirus. Then just check whether your antivirus tool removed the virus.
If not Go to start menu > Run > in the dialog box type regedit.
Navigate to the below tree :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\Microsoft Service Host
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\IeakHelpString
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\winlogos.exe
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\Huelar Services 2.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\NoFolderOptions
Delete the values and entries created by the virus.

If again in future the virus appears then you will need to format your pc

The most common way of these virus to spread is USB. As you had a your usb in a infected pc and then in yours. Huelar virus automatically creates directories and folders in the infected part. It creates a Autorun.inf file in every infected folder. It is a worm type virus and spreads very fast through a network. It changes folders in to executable files. If you click to open folder it will launch more viruses in your computer.
If not removed can cause a big harm to your pc. It disables task manager, regedit, etc.
To avoid these effects do the following :
Disable Autorun.
Install tools likeEset NOD32, HijackThis, and Remove Restrictions Tool.
Change the place of My Documents folder into another partition.
Turn-off System Restore utility.
Full Scan your pc with the above tools.
