About Browser Hijackers

Browser hijacking is regarded as the web’s constant problem that targets web browsers. It is a type of malicious software that alters your web browser’s settings and redirects you to sites or webpages that you had no intention of visiting. Browser hijacker malware is created for numerous reasons. It redirects you to the sponsored sites and injects adverts on your internet browser that helps its creator generate ad revenue. It could seem naive, but the majority of these websites are not legitimate and may pose a serious threat to your online safety. Additionally, hijackers can make the whole infected system fragile – other dangerous malware and viruses will use these opportunities to intrude into your computer system effortlessly.

Browser hijacking symptoms

There are many different symptoms that indicate the web browser has been highjacked: your browser’s home page is suddenly different; new bookmarks pointing to porn websites are added to your bookmarks; the default internet search engine and the default browser settings are modified; unsolicited new toolbars are added to your browser; numerous pop-up adverts show up and/or your browser pop-up blocker is disabled; your web browser starts running slowly or displays frequent errors; you’re blocked to access the websites of computer security solution providers.

How browser hijacker infects computers

There are several ways your PC could become infected with a browser hijacker. They usually arrive through spam e-mail, via file-sharing networks, or by a drive-by-download. They also come from add-on applications, also called browser helper objects (BHO), browser extensions or toolbars. Sometimes you may have inadvertently accepted a browser hijacker as part of an application package (generally freeware or shareware). An example of some notorious browser hijacker includes Conduit, Anyprotect, Babylon, DefaultTab, SweetPage, Delta Search, and RocketTab, however, the names are continually changing. Browser hijackers could record user keystrokes to collect potentially valuable information that leads to privacy concerns, cause instability on systems, drastically disrupt the user experience, and eventually slow down the computer to a point where it becomes unusable.

Browser hijacker removal

Some browser hijacking can be simply stopped by finding and removing the corresponding malware software through your control panel. Unfortunately, many of the software packages utilized to hijack a web browser are deliberately built to be hard to detect or remove. Furthermore, manual removals require in-depth system knowledge and thus could be a very difficult job for novice computer users. Professionals always suggest users remove any malicious software including browser hijacker by using an automatic malware removal tool, which is better, safer, and quicker than the manual removal technique. Safebytes Anti-Malware features a state-of-the-art anti-malware engine to help you prevent browser hijacker infection in the first place, and mop up any existing problems.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.

• Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.

• Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
• Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work.

Regardless of whether you have Windows Vista or XP, to create your new Outlook profile, first, you will have to click on the Control Panel, then User Account, and then Mail. Once you click on the Mail tab, the mail set up dialog box will open. In this dialog box there will be a ‘Show Profiles’ tab, click and then click the Add tab that appears next. Now type the name for your new Outlook profile and then click ‘OK’. After that, add an email account to go with the profile.
2. If Mapi32.dll is missing or corrupt, you will have to run ‘Fixmapi.exe’ to resolve the problem. It is located in the System32 folder inside the Windows directory in Windows Explorer.

• Therefore, first start Windows Explorer and then locate the following folder on your computer: C: /Program Files/Common Files/System/Msmapi1033
• Now find Fixmapi.exe and double click it
• After that locate the Mapi32.dll file and rename it to MSmapi32.old and press enter.
• Restart your computer when finished.

A word of advice for computer users is to scan for viruses with an antivirus program or a registry cleaner regularly to prevent the Mapi32.dll Outlook error from occurring in the first place. Viruses often latch onto .dll files and corrupt them. It’s always best to have a forward-looking approach.

If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.
