About Potentially Unwanted Applications

If you have ever installed freeware or shareware, chances are high that your computer can get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are almost always bundled up with free software which you download from the net or are also bundled within the custom installers on many download sites. PUPs did not really constitute pure “malware” in the strict sense of the term. Just like malicious software, PUPs cause problems when downloaded and installed on your PC, but what makes a PUP different is that you give consent to download it – although the truth is vastly different – the software installation package actually tricks you into accepting the installation. Irrespective of whether it is regarded as malware or not, PUPs are nearly always harmful to the user as they might bring on adware, spyware, keystroke logging, and also other bad crapware features on your computer.

What do PUPs do on your computer, exactly?

Potentially Unwanted Programs come in many forms and varieties, but in most instances, these are adware programs that show annoying pop-up adverts and advertisements on websites you check out. The PUPs also get installed into your computer in the form of web browser add-ons and toolbars. Not only they needlessly take up space on your computer screen, but toolbars may also manipulate search engine results, watch your web browsing activities, decrease your web browser’s efficiency, and decelerate your internet connection to a crawl. Potentially Unwanted Programs at times act quite similarly to viruses or spyware. Some PUPs include keyloggers, dialers, along with other software to gather your private details that may result in identity theft. These are programs that don’t do anything good for you; in addition to taking over space on your hard drive, they also slow down your computer, often modify settings without your approval, the list of bothersome features goes on.

Ways to avoid PUPs

• Always study the EULA and privacy statement. Don’t agree until you know precisely what you are acknowledging. • Choose the “custom” install whenever installing a software program. In particular, look closely at those small boxes that have been checked as default, where you may ‘agree’ to receive promotions or install software bundlers. • Use good antivirus software, like Safebytes Anti-Malware that offers real-time protection against PUPs. • Avoid adding a freeware program you do not use. Turn off or remove toolbars and web browser extensions you don’t really need. • Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid file-hosting sites where/when possible.

What you can do if Malware Prevents You From Downloading Or Installing Antivirus?

Practically all malware is bad, but certain types of malware do much more damage to your computer than others. Certain malware goes to great lengths to stop you from downloading or installing anything on your personal computer, particularly antivirus applications. If you are reading this right now, you have probably recognized that a malware infection is the real cause of your blocked web connectivity. So what to do if you need to install an antivirus program like Safebytes? There are a few steps you can take to circumvent this problem.

Some malware may target vulnerabilities of a specific browser that block the downloading process. If you seem to have malware attached to Internet Explorer, then switch over to an alternate web browser with built-in safety features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

Install and run anti-virus from the USB drive

Another solution is to create a portable anti-malware program on your USB stick. Adopt these measures to employ a thumb drive to clean your infected computer system. 1) Download Safebytes Anti-Malware or MS Windows Defender Offline onto a clean PC. 2) Plug the Thumb drive into the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format. 4) Choose the flash drive as the location for saving the file. Do as instructed on the screen to complete the installation process. 5) Now, plug the pen drive into the corrupted computer. 6) Double-click the anti-malware software EXE file on the USB flash drive. 7) Press the “Scan” button to run a full system scan and remove viruses automatically.

KMODE_EXCEPTION_NOT_HANDLED seems to be connected primarily to a third-party driver, e1d65x64.sys associated with the Intel(R) Gigabit adapter, NIC/Wired network NDIS (Network Driver Interface Specification) 6.x driver. Error is known to produce the dreaded blue screen of death or BSOD. Most usually error is connected with gaming on Windows 10 computer and it manifests itself during gaming sessions. If you are unlucky and you are faced with this unfortunate error we will be happy to try to help you and present with tips and tricks in order for you to find a solution for it. Before you proceed with the provided solutions, be sure you have sufficient disk space on the Windows drive, run Disk Cleanup and then run CHKDSK.

1) Run the Blue Screen Online Troubleshooter

Open Control Panel, change the view setting to icons. Click Troubleshooting, and click “View all” in the tasks pane. Click “Blue Screen”. This opens the Blue Screen Troubleshooter.

2) Run Driver Verifier

1. Start a Command Prompt window by selecting Run as an administrator, and type verifier to open Driver Verifier Manager.
2. Select Create standard settings (the default task), and select Next. You can also choose to Create custom settings to select from predefined settings, or to select individual options. For more information, see Driver Verifier options and rule classes and Selecting Driver Verifier Options.
3. Under Select what drivers to verify, choose one of the selection schemes described in the following table.

   Driver verifier table:

   Option	Recommended use
   Automatically select unsigned drivers	Useful for testing on computers that are running versions of Windows that do not require signed drivers.
   Automatically select drivers built for older versions of Windows	Useful for testing driver compatibility with newer versions of Windows.
   Automatically select all drivers installed on this computer	Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance.
   Select driver names from a list	In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time.

4. If you chose Select driver names from a list, select Next, and then select one or more specific drivers.
5. Select Finish, and then restart the computer.

3) Update network device drivers

Go to the official Intel website and try to find newer versions of drivers, if there are none perhaps you will need to revert back to the previous version.

4) Scan memory for issues

Run a memory test on your system, sometimes these errors can be traced back to a faulty RAM bank.

5) Stop over-clocking your PC

If you have overclocked your PC please reverse it back to its original state and see if that would solve the issue

6) Perform System Restore to the previous restore point

If none of the previous solutions have bared fruit, roll back to a previous restore point and that should solve the issue.

Microsoft starting as of today will block its Office 365 users if they are using Internet Explorer or early versions of Edge browsers. So if you are using older non Chromium Edge versions of Microsoft browsers you can no longer access Office services until you switch. Now normally I would fully support this kind of decision since Internet explorer is a slow and vulnerable browser and the edge is similar in that regard. The new edge browser is great and it should be used but the issue I have is that Office 365 is not free, it is a premium feature and I am wondering how Microsoft plans to deal with people that have already paid for service but suddenly cannot access it anymore.

Option 2 – via Windows 10 Settings

This is the second option you can check out to change the configuration of your mouse from being right-handed to being left-handed.

• First, right-click on the Windows icon and select Search.
• Next, type “mouse” and from the search results that appear, click on Mouse Settings.
• After that, select “Right” from the “Select your primary button” drop-down menu. This should set the mouse device from being right-handed to being left-handed.
