What is Bandoo?

Bandoo application, specifically product version 5.0.2.4762, is a bundled program. What does this mean? Simply, Bandoo, upon installation, installs additional programs, extensions, and add-ons to a computer and computer’s browser, without the knowledge of the user. This version of Bandoo concentrates on providing features for entertainment and also functionality/tools for backing up your computer files. Once executed, the file installs the iLivid Download Manager Software. Additional tools installed within the bundle include a Movie Toolbar and the thriving search engine ‘Ask.com.’ Technical details about Bandoo include: 

Digital Signature/Publisher:  Bandoo Media, Inc. Product Version: 5.0.2.4762 Entry Point:  0x000038AF

Assessment of Bandoo Potentially Unwanted Program

Interestingly, before the installation of Bandoo product version 5.0.2.4762 was complete, Spyhunter detected that the software was a PUP. After the installation was complete, product version 5.0.2.4762 of Bandoo added add-ons and extensions to both Internet Explorer and Chrome Browsers (these were the only 2 browsers used within the assessment). These appeared in the form of a Movie toolbar, providing quick access to movie trailers, reviews, ratings, and other video functionality, and ‘Ask’ (Ask.com) search engine.

Areas of Infiltration by Bandoo

Bandoo product version 5.0.2.4762 infiltrated several areas of the computer system. After installation, folders were neatly placed as files within all programs. Within “All Programs” there were 3 newly added programs. These included:

• iLivid
• Movies Search App for Chrome
• Movies Search App for Internet Explorer

The iLiVid application seems to be the main offer while the others, namely Movies App for Internet Explorer by Ask was featured as promotions or advertisements. Additionally, just below the 'END USER LICENSE AGREEMENT AND PRIVACY POLICY' a request was made that the user set Ask.com as both their homepage, new tab, and default search engine. This is just another well-concocted plan to get Internet users onto the 'Ask.com' search engine. Along with the 3 programs installed as a bundle,  a new folder was found within the computer's local drive. This program was termed OLBPre.

What is OLBPre?

OLBPre.exe is reputed as dangerous adware that weakens the security settings of a computer system. It's also covertly used for dropping files on a targeted computer, often without the user's consent or knowledge.

Manual Steps for Removal of Movie Search Apps

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: from your desktop, right-click on the ‘Start Button’.  A menu box will then appear.
• Step 2: from the menu box, click ‘Search’.
• Step 3: enter “Programs and Features” within the Input Box.
• Step 4: locate the installed apps. You should be able to see “Movies Search App for Chrome” & “Movies Search App for Internet Explorer”.
• Step 5: right-click on the names of the Apps (the ones you want to remove) when you’ve located them.
• Note: you will have to remove the apps one after the other.
• Step 6: after right-clicking the app, click the uninstall option (probably the only option available anyway).
• Note: If a box appears asking If you wish to ‘block’ or ‘allow’, select the allow option. That’s just the Publisher’s way to annoy you out of uninstalling the app.
• Step 7: follow instructions until the app is fully removed.
• Step 8: Repeat steps for the other app.

Since Bandoo also changed your search engine, you’ll have to reset that manually for Internet Explorer and Chrome. Follow the steps below:

• Step 1: Open your Internet Explorer browser.
• Step 2: Click the tool option located in the top right-hand corner of the page.
• Step 3: Click the “Internet Options” option.
• Step 4: Under the “General” tab, you’ll be able to see approximately 3 buttons. Click the button labeled ‘Use Default”.
• Step 5: At the bottom right-hand corner of the pop-up menu, select the “Apply” button and “OK”. That should do the trick.

Removal for Chrome Extension

This removal is simple.

• Step 1: Open your Chrome browser.
• Step 2: A pop-up box will be visible.
• Step 3: Click the “Remove from Chrome” option.

After removing the extensions/add-ons, perform another scan with Spyhunter. You’ll pick up a few threats. The second scan should clear up everything. To completely remove Bandoo from your computer, click here to download and install Spyhunter.

It seems that Microsoft is going to offer subscription and sales of individual office applications in the Windows Store. The office package will still be available as a package but for the first time, we will get single applications as standalone ones available for purchase. This is a very interesting decision by Microsoft and I fully support it, this time users will be able to pay less and to choose only applications that they need instead of paying for the whole package and not using it.

If you are browsing the web but suddenly encountered the ERR_BLOCKED_BY_CLIENT error on your Chrome browser in Windows 10, read on as this post will guide you in fixing this problem. This kind of error has already been reported by a number of Chrome users and it seems that the problem has something to do with a plugin or extension. Here’s the exact content of the error:

“This webpage was blocked by an extension (ERR_BLOCKED_BY_CLIENT)”

This kind of error, as pointed out, could be caused by an extension or plugin on Chrome that is blocking the web page. It is also possible that the version of Chrome is obsolete or that there could be more than 100 bookmarks in the Bookmark Manager. Before you troubleshoot the problem, make sure that you download the latest version of Google Chrome and see if it fixes the error. If it didn’t, then you can try opening a web page in Incognito Mode or disable and remove the extension that’s causing the problem. You could also try to remove any surplus bookmarks.

Option 1 – Try to open the web page in Incognito Mode

The first thing you can do to fix the problem is to try opening the web page in Incognito Mode. When your browser is in this mode, it will work without extensions. This would help in fixing the problem especially if it was caused by some extension or toolbar in your browser. All you have to do is open any web page in Chrome and tap the Ctrl + Shift + N key combination to open a window in Incognito Mode.

Option 2 – Try to disable and get rid of the problematic extension

After you’ve isolated the problem and have determined that an extension is the one that’s causing it, then the next thing you have to do is to disable or get rid of that extension.

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Option 3 – Try removing surplus bookmarks

If your Chrome browser is already supporting more than 100 bookmarks, you might want to consider deleting them as it could also be one of the reasons why you’re getting the ERR_BLOCKED_BY_CLIENT error. To remove these bookmarks, just open the bookmark library by typing this address “chrome://bookmarks/” in the address bar of Chrome and tap Enter and press Shift and then select the surplus bookmarks by using the arrow keys. After that, click Delete to get rid of them.

Option 4 – Try clearing browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BLOCKED_BY_CLIENT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

KMODE_EXCEPTION_NOT_HANDLED – What is it?

Some users installing or upgrading to Windows 10 experienced the theKMODE_EXCEPTION_NOT_HANDLED Blue Screen of Death (or commonly known as BSOD) error. This error can be due to different types of things, ranging from software to driver issues. When you experience this BSOD error while trying to install Windows 10, it will prompt you to restart your computer every single time you experience it. In most cases, you will also not be able to proceed with the Windows 10 set-up.

Solution

Error Causes

The “KMODE_EXCEPTION_NOT_HANDLED” error is normally caused by:

• Hardware incompatibility
• A faulty device driver or system service

Further Information and Manual Repair

You won’t be able to successfully upgrade or set up Windows 10 if you continue to encounter this BSOD error. Note that this error will always prompt your computer to restart every time it happens, preventing you from completing the Windows 10 set-up.

If you’re not tech-savvy or not capable of debugging this issue, it’s highly advisable to proceed with the basic troubleshooting techniques available in this link.

After troubleshooting, below you’ll find a few solutions to rectify the issue.

Method 1 – Check The Cause of The BSOD Error

Two common causes of the KMODE_EXCEPTION_NOT_HANDLED issue are hardware incompatibility and faulty device driver or system service.

If you experience this error, check first if any of your newly installed hardware is compatible with Windows 10. You can find the required hardware for Windows 10 from this link. 

If all your hardware is compatible with Windows 10, you might need to check the device driver or system service. Review the bug check message. If any of the drivers you have is listed in the message, either disable or uninstall them before upgrading or setting up Windows 10.

You might also find it useful to check the System Log available in the Event Viewer for other error messages that can help you figure out the driver or device that’s causing the error. Running hardware diagnostics can also be useful.

Method 2 – Disable (or preferably uninstall) Software Before Upgrading

If you’re upgrading Windows 10 from Windows 7 or Windows 8.1, you might need to disable or uninstall the software first. First, try uninstalling your Antivirus utility before starting the upgrade. Restart a few times before starting the Windows 10 installation. If you’re upgrading using the Windows 10 update, make sure that you disconnect from your Wi-Fi or Internet LAN (Ethernet) connection as soon as the download reaches 100% before attempting to start the set-up. Other users also reported that the cause of the KMODE_EXCEPTION_NOT_HANDLED issue is BitDefender. If this is what happened in your case, it will show in the error message such as KMODE_EXCEPTION_NOT_HANDLED (bdselfpr.sys). Users reported that a common solution for this is renaming the file. In the case of BitDefender, try renaming it to bdselfpr.s__. However, make sure to do this cautiously. Sometimes, renaming a file will even do more damage than good.

Method 3 – Disable/Disconnect From Hardware

If you’re connected to any general USB devices (such a smart card reader), disable it. If your computer is connected to other external devices, disconnect all of them. Examples of this include gaming controllers, printers, external hard disk, USB keys, and other non-essential devices).

Method 4 – Other Troubleshooting Steps

Other troubleshooting steps include:

• Upgrade using an .ISO file, instead of directly upgrading from Windows Update. When you do this, make sure you’re disconnected from the Internet during installation. If the process started and you forgot to disconnected, it’s best to restart the installation.
• If you’re connected to a domain while trying to set up Windows 10, disconnect and use a local account.
• If you’re using a SCSI hard disk, connect a thumb drive with the drivers for your storage device. While Windows 10 is setting up, click on the Custom Advanced Option. Using the thumb drive, use the Load Driver command to load the SCSI drive.
• Another possible cause of this error is due to BIOS incompatibility. BIOS issues can be solved by upgrading your version of your system BIOS. If you don’t know how to do this, refer to your BIOS manufacturer’s website.

Method 5 – Use A Trusted Automated Tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

When you get the error information, "The Software Can Not Begin Because MSVCR100.Dll Is Missing", what this implies is that the Computer will be lacking the  MS Visual C++ 2010 libraries. The malfunction is rather frequent throughout installations. It doesn't matter the number of times you try to reinstall the program. The malfunction can happen whether you've been utilizing your pc for many years, or it's really a recent one.

Solution

Error Causes

a) Missing MSVCR100.DLL: As the problem message indicates, you get this information mainly because MSVCR100.DLL is completely missing. b) Broken MSVCR100.DLL: When the msvcr100.dll is broken, you will also get the same error, suggesting the software won't start. The thing you need to understand is the fact that MSVCR100.DLL is playing an important role in the application referred to as MS Visual C++ 2010 Redistributable Package. Without the MS Visual C++ 2010 Redistributable Package, any software that you simply make an effort to install won't start. You could possibly complete installing it by pursuing proper installation procedures, and then end up getting the "The Software Can Not Begin Because MSVCR100.Dll Is Missing" error.

Further Information and Manual Repair

If you get the "The Software Can Not Begin Because MSVCR100.Dll Is Missing" error information on an effective setup of any software, you shouldn't worry. You can really repair the issue and commence your recently installed software without any more hassle. Start by checking whether you presently use 64-bit or 32-bit Windows. Visit the start button, in case you use Winxp. Type winver. On the window that appears, click Run, subsequently push enter. Head to Start, in case you use both Win7 or Vista. Subsequently, click on the search box and type “Computer”. Right-click windows and subsequently click on Properties. Under Windows Edition, you'll find whether your Windows is 64-bit or 32-bit. Search for the correct variation of MS Visual C++ 2010 Redistributable Package, as soon as you discover whether your Windows is 64-bit or 32-bit. Down load the x86 variant of MS Visual C++ Redistributable Package if your version is 32-bit and you must obtain the x64 variant of MS Visual C++, for those who own a-64-bit version of Windows Operating System. You must never obtain MS Visual C++ 2010 Redistributable Package from third-party websites. This is because Microsoft doesn't charge a cent for the files. The files are openly and easily available on Microsoft. These files come in many different variants. Consequently, select what's suitable for your own Computer with regards to the version of Windows which you operate.

• Never pick the edition of MS Visual C++ 2010 Redistributable Package that's not compatible or appropriate to your Windows Operating System.

Make use of the release date, when installing MS Visual C++ 2010 Redistributable Package. You might also look out for Service Pack 1 and obtain it for your Windows. Service Pack 1 only ensures that you simply obtain the latest edition. As soon as you end installing the most up-to-date version of MS Visual C++ 2010 Redistributable Package as demonstrated above, reboot your computer and you'll not have to worry about getting the annoying"The Software Can Not Begin Because MSVCR100.Dll Is Missing" error message anymore.

Can’t connect to this network Internet connectivity issues present a complex problem with simple solutions for PC and laptop users. First, it is usually recommended that users rule out problems with the internet connection, router, and Wi-Fi settings before proceeding to troubleshoot settings on your PC/laptop. Once the rest are ruled out, we can then proceed with the following troubleshooting steps and guidelines to fix your wifi connection issue: The first step is to update your windows network adapter driver. Connectivity problems may arise if your network driver is not updated or if it is incompatible with the network adapter. To do so, you may resort to any third-party driver scanning and installing programs found online. This solution should have resorted if users don’t want the hassle of perusing through windows settings that users may not be familiar with. However, this solution requires a pre-existing internet connection other than wifi, so it is recommended you have a backup internet connection via ethernet.

The second step is to uninstall the driver for your network adapter. This solution is to be reported if there is an issue with the driver as restarting the PC after the following steps let windows reinstall the driver again:

• Open the quick access menu on your keyboard by pressing the Windows key and X key at the same time and select “Device Manager” from the menu list.
• From the list of devices, select “Network Adapters”
• Usually on the top of the list is the Wireless Network Adapter
• Right-click the Wireless Network Adapter and select the option to “Uninstall device”
• You will be given a confirmation in a new separate window to proceed. Click “Uninstall” to proceed.
• After completing the previous steps, try rebooting your Windows PC and reconnecting to see if it works.

A third step is to disable the 802.1 1n modes of your network adapter by following the next steps:

• First press the Windows logo key and the X key at the same time to bring up the quick-access menu. And like the previous step, select “Device Manager”
• From the list of devices, select “Network Adapters”
• Right-click the Wireless Network Adapter from the drop-down menu and select properties
• Under properties, select the “Advanced” tab then select the 802.1 1n Mode. To the right drop-down menu change the option to  “Disabled” and click “Ok”
• After, try to re-establish the connection to see if the steps have worked.

In the event that any of the preceding did not fix your problem, it helps to take a second look at the router and network settings using the interface provided by your ISP. A simple reset to the back of your router often fixes the issue. Also, try to check if you have any other administrative capabilities over the network to determine whether your device, in particular, has been MAC filtered or if the frequency of your wireless adapter is not compatible with the broadcast frequency of your router.

5 Windows 10 Upgrade Errors

The recently released Windows 10 captivated the mass but its rollout, polished as it might have been, proved everything but seamless. Surf the Internet and you’ll get the gist. People are complaining and they need assistance. Assistance with what you might ask? Many have attempted to make an upgrade but failed after encountering various strange combinations of letters and numbers. These are none other than error codes. If you’ve tried and failed, feast your visuals below as you might encounter one of these 5 Windows 10 Upgrade errors.

Error Code 0x80073712

Encountering error code 0x80073712 in no way implies that you need to throw out your computer system and acquire a new one. Not at all! This error code simply means that a very important file to Windows might have gone missing or corrupted. This file is crucial to Windows update so without obtaining this file, you won’t be able to proceed with the update.

Error Code 0x800F0923

Likely, there are many programs and drivers installed on your computer. They all play a vital role. However, if you’ve received error code 0x800F0923, it might be time to consider or turn your eyes to installed drivers on your system. Why? Error code 0x800F0923 means that there’s a driver or driver on your current Operating System that’s not compatible with Windows 10. There’s clearly a dilemma here.

“We couldn't complete the updates. Undoing changes. Don't turn off your computer.” Or “Failure configuring Windows Updates. Reverting changes”

That’s a pretty odd error but I will say it's slick… That Windows 10 upgrade error is straightforward. Microsoft is just letting you know that they won’t be able to complete the update to Windows 10 and so they are putting your computer back to where it was. How nice of them.

The error messages above are pretty generic and will manifest when the upgrade fails for one reason or the other. To resolve this issue, you’ll most definitely have to decipher what error code was presented. Identifying that will provide a glimpse into exactly what steps you need to take.

The Update Isn't Applicable to Your Computer

I don’t know about you but I strongly believe Microsoft is subtly letting you know that your computer system is old and needs to be thrown out. Also, this update could imply that your PC needs to install important updates to rev you up to the requirements. All relevant updates to your computer must be installed before you can get past this stage.

Error… “Something Happened”

This Windows 10 upgrade error has been the talk of the Internet. In fact, users of Windows OS have been making it a mockery. Clearly, not many have had success after encountering this error. Obviously, “something happened” but it’s just not easy to decipher what went wrong. Microsoft is still trying to figure it out.

Solution

Recently, a number of Windows 10 users getting an error on their computers that state, “Windows can’t find one of the files in this theme”. According to the affected users, this error occurs at random times even when they didn’t make any changes to their computer’s theme prior to getting the error. If you are one of these users, read on as this post will help you resolve this problem. If you click on the Yes button of the dialog box where the error is displayed, it won’t fix the problem as you will still get the same error from time to time. This kind of error could be caused by the executable file named “SettingSyncHost.exe”. It is possible that this executable file is unable to sync your theme all over your computer. On the other hand, it could also be due to some problems with the active theme. To resolve this issue, you can try to change the active theme, or disable the custom screensaver or disable theme syncing on your computer, as well as run a System File Checker or run the DISM tool. For more instructions, follow the options given below.

Option 1 – Try to change the active theme

The first thing you can do to fix the error is to change the active theme of your computer since the SettingSyncHost.exe file might not be able to properly sync the theme on the computer.

• Go to Settings and click on Personalization.
• Next, click on Themes and scroll down to apply a theme, and change the theme of the operating system.
• After that, tap the Win + R keys to open the Run dialog box and type “%windir%ResourcesThemes” in the field, and then tap Enter to open the folder where the theme files are located.
• Once you’re done, right-click and select delete for the active theme to remove the theme and its resources. This should fix the root cause of the problem. If not you can try to create a new Windows 10 theme and save it.

Option 2 – Try to disable the custom screensaver

The custom screensaver is a part of the mechanism of the lock screen. Although they were needed in the earlier Windows versions to prevent the discoloration of CRT monitor screens, they are no longer needed in the current version of Windows. Thus, you can try to disable it as it could be the one that’s causing the problem.

• Click on the Start button and go to Settings > Personalization > Lock screen.
• Here, scroll down and click on the Screen Saver settings.
• After that, select the “Screen saver to (None)” option from the drop-down menu. This will disable the custom screensaver.

Option 3 – Try to disable theme syncing on your computer

You could also try to disable the theme sync feature to fix the problem. This has worked out for some users. To do so, follow these steps:

• Click on the Start button and go to Settings > Account > Sync your settings.
• From there, toggle off Themes in the individual sync settings column. This will disable the Theme syncing.
• Restart your computer and see if the problem is now fixed.

Option 4 – Run the DISM tool

The next thing you can do is run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the “Windows can’t find one of the files in this theme” error. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the problem is now fixed.

Option 5 – Run the System File Checker

System File Checker or 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 to good system files that might be the cause why you’re getting the “Windows can’t find one of the files in this theme” error. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

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.

• Now restart your computer and see if the problem is fixed or not.
