Arrival Details

This Potentially Unwanted Application arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Installation

This Potentially Unwanted Application adds the following processes:

  • taskkill.exe /f /im "rgcl.exe"
  • "%System Root%\Program Files\Xtron ~System ~Care_{username}\rgcl.exe" getwebparam

(Note: %System Root% is the Windows root folder, where it usually is C:\ on all Windows operating system versions.)

It creates the following folders:

  • %System Root%\Program Files\Xtron ~System ~Care_{username}
  • %System Root%\Program Files\Xtron ~System ~Care_{username}\x86
  • %System Root%\Program Files\Xtron ~System ~Care_{username}\x64
  • %All Users Profile%\Xtron ~System ~Care_{username}
  • %All Users Profile%\Microsoft\Windows\Start Menu\Programs\Xtron ~System ~Care_{username}
  • %User Temp%\is-HLJRN.tmp\_isetup

(Note: %System Root% is the Windows root folder, where it usually is C:\ on all Windows operating system versions.. %All Users Profile% is the common user's profile folder, which is usually C:\Documents and Settings\All Users on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\ProgramData on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit). . %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)

Other System Modifications

This Potentially Unwanted Application deletes the following files:

  • %All Users Profile%\Microsoft\Windows\Start Menu\Programs\Xtron ~System ~Care_{username}\Xtron ~System ~Care.pif

  SOLUTION

Minimum Scan Engine:

9.850

Step 1

Before doing any scans, Windows 7, Windows 8, Windows 8.1, and Windows 10 users must disable System Restore to allow full scanning of their computers.

Step 2

Identify and terminate files detected as PUA.Win32.XtronSystemCare.F

[ Learn More ]
  1. Windows Task Manager may not display all running processes. In this case, please use a third-party process viewer, preferably Process Explorer, to terminate the malware/grayware/spyware file. You may download the said tool here.
  2. If the detected file is displayed in either Windows Task Manager or Process Explorer but you cannot delete it, restart your computer in safe mode. To do this, refer to this link for the complete steps.
  3. If the detected file is not displayed in either Windows Task Manager or Process Explorer, continue doing the next steps.

Step 3

Delete this registry value
