How to Uninstall BitDefender QuickScan and ActiveXby Justen Everage
QuickScan, an antivirus program distributed by BitDefender, allows users to check for viruses and other malicious software while browsing the Internet. When QuickScan is installed on a computer, an ActiveX file is installed along with it, allowing the program to access information used by Internet browsing software. The ActiveX file installed and used by QuickScan will be removed when QuickScan is uninstalled from a computer.
Open Internet Explorer. From the main menu, locate and open the Tools sub-menu. Select the "Manage Add-ons" option. Click on the "Toolbars and Extensions" button on the left side of the add-on manager.
Scroll through the list of installed add-ons in the add-on manager. QuickScan, along with its installation date and current status, will be listed under the BitDefender heading.
Click on the QuickScan button and choose the disable option. Close the add-on manager and close Internet Explorer. The QuickScan antivirus software and accompanying ActiveX control is now disabled and ready for deletion.
Open the "My Computer" icon from the computer's start menu. Double-click the C:drive and open the Windows folder. Locate the folder titled "Downloaded Program Files" and open it. Delete all QuickScan related files from this folder. If unsure about which files are associated with QuickScan, note that all QuickScan files begin with the four letters "qsax." Files unrelated to QuickScan are unlikely to contain this phrase; however, for verification purposes, file-manufacturer information may be found in any file by right-clicking it and selecting properties.
Open Internet Explorer to confirm that QuickScan is removed from the system.
- check Chrome and Firefox do not use ActiveX controls; however, BitDefender's QuickScan may be removed from these browsers in a similar manner. Chrome users may open the extensions options from the tools menu and select uninstall on the QuickScan icon. Firefox users will find the removal option in "Add-ons," which is found under "Tools."
