Easy Remove ShopAtHome Guide

ShopAtHome Toolbar is a browser extension. This extension tracks information when you visit a website, whether typing in the URL or clicking a link, the Browser App recognizes whether the URL is that of an Affiliate Store, and, if so, may redirect you through the affiliate network site to the Affiliate Store’s website, at which time, a tracking cookie will be placed in your browser. This cookie is the tracking mechanism that will follow your transaction with the Affiliate Store.

During installation, the Browser App may automatically change the default search engine used by your Web browser, whether via a built-in search box or otherwise, to our search engine. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times.

Multiple anti-virus scanners have detected possible malware in ShopAtHome.com Helper and are therefore classified as potentially unwanted and flagged for optional removal.

About Browser Hijackers

Browser hijacking is actually a form of an unwanted program, often a web browser add-on or extension, which then causes modifications in the browser’s settings. Browser hijackers can do a variety of things on your PC. The idea would be to force users to visit certain sites that are looking to increase their visitor traffic and generate higher ad income. A lot of people assume that these kinds of sites are legitimate and harmless but that is incorrect. Almost every browser hijacker poses an actual threat to your online safety and it is important to classify them under privacy risks. They do not just screw up your web browsers, but browser hijackers could also modify the system registry, leaving your computer or laptop susceptible to other forms of hacking.

Browser hijacking signs and symptoms

Signs that your web browser is hi-jacked include: 1. the home page of your web browser is changed suddenly 2. you find yourself regularly directed to some other web page than the one you actually meant 3. The default search page of the browser is changed 4. you find many toolbars in your web browser 5. you see a lot of pop-ups on your computer screen 6. your internet browser starts running sluggishly or displays frequent glitches 7. Inability to navigate to particular sites, particularly anti-malware as well as other security software sites.

How browser hijacker infects PCs

Browser hijackers infect computers through malicious email attachments, downloaded infected documents, or by checking out infected internet sites. They also come from add-on programs, also called browser helper objects (BHO), web browser extensions, or toolbars. Other times you may have unintentionally accepted a browser hijacker as part of a software program package (generally freeware or shareware). Popular examples of browser hijackers include Conduit, CoolWebSearch, Coupon Server, OneWebSearch, RocketTab, Delta Search, Searchult.com, and Snap.do.

The best ways to get rid of browser hijackers

Some hijackers could be removed simply by uninstalling the related freeware or add-ons from the Add or Remove Programs in the Microsoft Windows Control Panel. Sadly, the majority of the software packages utilized to hijack a web browser are deliberately designed to be hard to detect or remove. Besides, browser hijackers can modify the Windows registry so it can be very difficult to fix manually, particularly if you are not a very tech-savvy person.

Help! Malware Preventing Anti-virus Installation And Access To The Web

If you suddenly see a black border in your computer’s display then you might be wondering how come this happened but worry not for this post will give you a couple of suggestions that could help you resolve the problem. The black bar could appear at the bottom or just the sides of the screen. Whichever it may be, there are options you can check out. Refer to the options givens below and make sure to follow them carefully.

Option 1 – Try checking the screen resolution

You might want to try checking the resolution of your screen.

  • Next, go for the “100% (Recommended)” option under Scale and layout for the size of the text, apps, and other items.
  • After that, select the Recommended setting again under Resolution.
Now check to see if the black bars are still there. They should be gone at this point, but if for some strange reason nothing has changed, then attempt the steps below.

Option 2 – Try updating Graphics & Monitor drivers

You might want to try updating your graphics and monitor drivers if you haven’t updated them for some time now. To do that, refer to these steps:
  • First, boot your computer into Safe Mode.
  • After that, tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. From there, look for the Graphics drivers or the Monitor drivers and then click each one of them.

Option 4 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.

Show more/less details when copying/moving
When we initiate the copy or move files command we get a dialog that shows us the progress of the current operation, under that bar we can click on the little arrow to expand the bar into so-called more details view where we get more information like which file is being copied, more detailed graph, etc. Windows will remember the last option we had and next time when we start the same process it will open the last view. But what if we want to only have one view always open as default, even if we change it? Let's say that we always want to have a detailed view opened always as our default even if we switch to a minimal one? Well with some tweaks in the registry of Windows we can. Note that this guide will require changing things in the registry of Windows itself, it is always smart and recommended to make a safe backup of your registry, just in case.

However, pinpointing the exact cause is quite difficult. Worry no more for the following fixes provided below can help you resolve the NMI_HARDWARE_FAILURE Blue Screen error no matter what the cause of the problem is.

Option 1 – Try removing hardware or drivers that you’ve installed recently

If you have recently installed some hardware or drivers, you might want to disable or remove them since external devices are proven to be one of the factors that trigger Blue Screen errors like NMI_HARDWARE_FAILURE. All you have to do is physically disconnect any external devices that are connected to your computer and then check if it fixes the BSOD error or not.

Option 2 – Try to rollback, update, or disable the Graphics card drivers

Since the NMI_HARDWARE_FAILURE Blue Screen error has something to do with Graphics card drivers, you can either roll back, update or disable them depending on your preference in order to resolve the error.

Thus, you have to follow the potential fixes provided below to fix the problem but before you do that, make sure that you create a System Restore point first. After that, follow each one of the following options.

Option 1 – Put your PC in a Clean Boot State

The first thing you can do to resolve the problem is to put your computer in a Clean Boot State. It could be that there is a third-party program that’s preventing the toggle button from functioning. To isolate this possibility, you need to put your computer in a Clean Boot State.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • Now check if you can now use the toggle button of the Location service or not.

Option 2 – Try to use the Registry Editor

If putting your computer in a Clean Boot state didn’t fix the problem, you might want to make some adjustments in the Windows Registry via Registry Editor.
  • Tap the Win + R keys to open the Run utility and type “regedit” in the field and then tap Enter to open the Registry Editor.
  • After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceslfsvcTriggerInfo
  • From there, select the Key (folder) named as “3” and right-click on it, and then delete it.
  • Once done, exit the Registry Editor and restart your computer.

Option 3 – Try to use the Windows Services Manager

  • Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Services Manager.
  • Next, look for the “Geolocation Service” entry from the list of services.
  • Once you find it, right-click on it and select Properties. This will open a new mini window.
  • From there, make sure that it is “Running” and its Startup Type is set to “Automatic”.
  • After that, close the Services Manager and check if the problem is now resolved.

Option 4 – Try to use the Group Policy Editor

  • Tap the Win + R keys to launch Run and type “gpedit.msc” in the field and click OK to open the Group Policy Editor.
  • After that, navigate to this path: Administrative TemplatesWindows ComponentsLocation and Sensors
  • Next, double click on each one of the following settings and select the “Not configured” or “Disabled” option.
    • Turn off location scripting
    • Turn off location
    • Turn off sensors
  • Once done, navigate to this path: Administrative TemplatesWindows ComponentsLocation and SensorsWindows Location Provider
  • From there, double click on the “Turn off Windows Location Provider” policy setting and set its configuration to either “Disabled” or “Not configured”. You should see the following description of the policy setting in the window:
“This policy setting turns off the Windows Location Provider feature for this computer. If you enable this policy setting, the Windows Location Provider feature will be turned off, and all programs on this computer will not be able to use the Windows Location Provider feature. If you disable or do not configure this policy setting, all programs on this computer can use the Windows Location Provider feature.”
  • Now restart your computer.

Device attached to system is not functioning
If you are trying to connect your mobile or external device to your Windows 10 computer but suddenly encountered an error saying, “A device attached to the system is not functioning”, read on as this post will guide you on how you can resolve this error using a couple of potential fixes. In this case, it is possible that the connected device is not working for some reason and this error pops up when you connect your device or when you try to move or copy files from your computer to your external device and vice versa. As you can see, the error message is pretty straightforward, and it mostly occurs when you connect plug and play devices such as USB drives, printers, external storage devices, and many more. And when you open the Device Manager to check the device, you will most likely see a yellow exclamation mark on the device which indicates that the device is currently having problems. To fix this problem, there are several options you can check out. You need to check the status of the device or check the compatibility between the external device and the drive types. You also have to make sure that the device is connected properly or check if the device has been formatted properly. For more details, follow the given suggestions below.

Option 1 – Try to check the status of the device

The first thing you can do to get rid of the error is to check the status of the external device, especially if it’s a plug-and-play device. So when your computer boots, check if it is able to detect the device or not.

Option 2 – Try to check the compatibility between the external devices and drivers

As you know, when you connect an external device to your computer, Windows installs drivers to communicate with the device, the same way as any hardware you connect to the motherboard and if the driver ends up getting corrupted or is incompatible, then you need to update the device driver. To do that, follow the steps below.
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the driver the external device related to and then right-click on each one of the Device drivers and select the Update Driver from the menu.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the device drivers didn’t work, you can try to reinstall them instead.

Option 3 – Try checking the hardware connections

The first thing you have to do before you further troubleshoot the problem is to check the hardware connections of your computer and see if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 4 – Check if the device is formatted properly

You might also want to check if the external device is properly formatted especially if you’ve recently formatted it. If a device wasn’t formatted properly, then it’s no wonder why you’re getting the “A device attached to the system is not functioning” error. To fix this, you need to use Disk Management. From there, you can find the devices connected but are not visible. If you are using an admin account, then to fix this error, you have the option to format the drive or create new partitions using the interface. Once you do this, it should resolve the problem.

Option 5 – Try to run System File Checker or SFC scan

  • 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.
  • Once done, restart your computer.

Option 6 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • Now try to connect your device or copy the files to your external device again and check if the error is now gone.

Android malware spies while posing as a Update
New malware with extensive spyware capabilities steals data from infected Android devices and is designed to automatically trigger whenever new info is read to be exfiltrated. The spyware can only be installed as a 'System Update' app available via third-party Android app stores as it was never available on Google's Play Store. This drastically limits the number of devices it can infect, given that most experienced users will most likely avoid installing it in the first place. The malware also lacks a method to infect other Android devices on its own, adding to its limited spreading capabilities. However, when it comes to stealing your data, this remote access trojan (RAT) can collect and exfiltrate an extensive array of information to its command-and-control server. Zimperium researchers who spotted it observed it while "stealing data, messages, images and taking control of Android phones."

What happens when malicious software is installed

"Once in control, hackers can record audio and phone calls, take photos, review browser history, access WhatsApp messages, and more," they added. Zimperium said its extensive range of data theft capabilities includes:
  • Stealing instant messenger messages;
  • Stealing instant messenger database files (if the root is available);
  • Inspecting the default browser's bookmarks and searches;
  • Inspecting the bookmark and search history from Google Chrome, Mozilla Firefox, and Samsung Internet Browser;
  • Searching for files with specific extensions (including .pdf, .doc, .docx, and .xls, .xlsx);
  • Inspecting the clipboard data;
  • Inspecting the content of the notifications;
  • Recording audio;
  • Recording phone calls;
  • Periodically take pictures (either through the front or back cameras);
  • Listing of the installed applications;
  • Stealing images and videos;
  • Monitoring the GPS location;
  • Stealing SMS messages;
  • Stealing phone contacts;
  • Stealing call logs;
  • Exfiltrating device information (e.g., installed applications, device name, storage stats).

How does it work?

Once installed on an Android device, the malware will send several pieces of info to its Firebase command-and-control (C2) server, including storage stats, the internet connection type, and the presence of various apps such as WhatsApp. The spyware harvests data directly if it has root access or will use Accessibility Services after tricking the victims into enabling the feature on the compromised device. It will also scan the external storage for any stored or cached data, harvest it, and deliver it to the C2 servers when the user connects to a Wi-Fi network. Unlike other malware designed to steal data, this one will get triggered using Android's contentObserver and Broadcast receivers only when some conditions are met, like the addition of a new contact, new text messages, or new apps being installed. "Commands received through the Firebase messaging service initiate actions such as recording of audio from the microphone and exfiltration of data such as SMS messages," Zimperium said. "The Firebase communication is only used to issue the commands, and a dedicated C&C server is used to collect the stolen data by using a POST request."

Camouflage

The malware will also display fake "Searching for the update.." system update notifications when it receives new commands from its masters to camouflage its malicious activity. The spyware also conceals its presence on infected Android devices by hiding the icon from the drawer/menu. To further evade detection, it will only steal thumbnails of videos and images it finds, thus reducing the victims' bandwidth consumption to avoid drawing their attention to the background data exfiltration activity. Unlike other malware that harvests data in bulk, this one will also make sure that it exfiltrates only the most recent data, collecting location data created and photos taken within the last few minutes.
