Answer: If your web browsers are running slow, or your plagued with pop-ups, advertisements, and toolbars, you may have an adware infection. Adware is unwanted software that is designed to hijack your web browser, leading you to different searches and littering your browser with ads. The first step towards removing these infections is by uninstalling unknown programs through the Control Panel. The process varies a little depending on your version of Windows: Windows 10 and 8 - Right-click on the Windows button and select "Control Panel." Windows 7, Vista, and XP - Click the Start button and select "Control Panel" from the Start menu. This will display a list of all of the programs installed on your computer. You can sort the list by install date, which can help you find programs that may have been installed recently without your knowledge. Go through each program on the list and make note of the ones you don't recognize. Perform a web search for each unrecognized entry to determine if it is an unwanted program. Follow the prompts to remove the program from your system. Repeat for any additional programs that you want to remove. This would be a good time to remove programs that you do recognize, but no longer need. Old games, unused browsers, utilities that you used once and then never used again, and other legitimate programs can add to your computer's bloat. Remove them to free up some space and potentially speed up your computer's start-up time. This is a free utility that will scan for common adware and malware, and then remove what it finds. You can download AdwCleaner from toolslib.net/downloads/viewdownload/1-adwcleaner/. Click the "Scan" button in AdwCleaner to scan your computer for infections. This may take 20 minutes or so to complete. Once the scan is complete, click "Clean" to remove any infections that AdwCleaner found. The free version of this program can find and remove most infections. You can download the installer by visiting malwarebytes.org and selecting "Download." You can then click the "Download Free Version" button. Run the installer after downloading it to install the program. Launch Malwarebytes Anti-Malware and download any updates if prompted to. Start a scan of your computer, which may take 20-30 minutes. Remove anything that the scan finds by clicking "Quarantine All" after the scan has completed. Many adware infections will add links to your browser shortcuts, which will cause the wrong website to load even after removing the infection. A free shortcut cleaner created by the anti-malware community can scan all of your shortcuts and remove malicious links. You can download the scanner here. Run the downloaded program to quickly scan and fix your browser shortcuts. Your web browsers may still have lingering remnants of the malware removed by the scanners. Resetting your browsers will remove any additional software and return them to their default settings: Internet Explorer - Click the Tools button and select "Internet options." Click the "Advanced" tab and click "Reset." Check the "Delete personal settings" box and click "Reset." Chrome - Click the Chrome Menu button and select "Settings." Click "Show advanced settings" and then scroll to the bottom. Click "Reset settings" and then click "Reset." Firefox - Click the Firefox Menu button and then click "?". Select "Troubleshooting Information" and then click "Refresh Firefox." Click "Refresh Firefox" again to confirm. After you're finished cleaning and resetting your shortcuts and browsers, you should reboot your computer and run both scans again. There may still be lingering traces that show up again after a reboot.

Problem: Write an article based on this summary: Define the elements of the use case. Define how the user will use the technology or process. Describe the normal course of events for each use case. Repeat the steps for all other functions and users.

Answer: All of these elements are required in every use case. Use cases accumulate scenarios. They define how a user uses a system, what happens when the system succeeds, and what happens when it fails. Each scenario describes a procedure and what happens as each step progresses. Users are all of the people who will engage in the activities described in the use case. For example, if you are writing a use case for logging into a software system, the users would be anyone who must log in. Preconditions are those elements that must be in place prior to the start of the use case. For example, users with permission to use the system have been identified and entered into the system ahead of time, so the system will recognize their usernames and passwords when entered. The basic flow is the procedure the users use to achieve the primary goal of the system and how the system responds to their actions. For example, the user inputs a username and a password, and the system allows the user in. Alternate flows explain less common actions. For example, the user is on a different computer and must answer a security question. Exception flows detail what happens when the user cannot achieve the goal. For example, the user inputs an invalid user name or password. Post conditions are those elements that must be present when the use case is completed. For example, the user can proceed to use the software. Each thing the user does becomes a separate use case. The scope of a use case is narrow. For example, if a company is implementing new software to create purchase orders, you could write several use cases about this. One use case might be about how users log in to the system. Another might be about how to run requisition reports. List all of the functions of the new technology or business process you are analyzing, and write a use case for each one. Outline everything the user does and how the technology or process responds to those actions. In a use case about how users log into a software system, the normal course of events would state that the user enters a username and password. The software responds by verifying the user and either granting or denying access to the system. Alternate flows and exception flows are written to describe the actions when there are obstacles to the goal. If the user is denied access because the system didn't recognize her computer, she may be prompted to verify her identity by answering a security question. If the user inputs an invalid username or password, she may be prompted to answer a security question and enter an e-mail address to receive new log in information. Write use cases for all of the other functions of the software or business process. Identify the users for each function, and write the steps for the normal course of events. Explain contingencies for when the goal cannot be achieved. For each step, explain how the system responds to the actions of the user.

Problem: Write an article based on this summary: Use 90% rubbing alcohol if the damp cloth didn't do the trick. Hold an alcohol-soaked cloth over the area if wiping it didn't work. Slide tape over the stuck-on residue if you didn't have luck with alcohol. Try using a mildly abrasive scrub pad if a cloth didn't work. Use a blow dryer to loosen the gunk if all else fails.

Answer:
To remove stubborn adhesive residue, dip a corner of the microfiber cloth in rubbing alcohol. Once again, use tight, circular motions to scrub off the sticker goo. If glue residue is still sticking around, dip your cloth in alcohol (or vinegar diluted with water) again. Place the cloth onto the sticky area, and let it sit for 2 to 3 minutes. That should dissolve any remaining stubborn gunk. Rubbing alcohol shouldn't discolor or damage the plastic or aluminum used for laptop casings. However, if you want to stay on the safe side, check the area every 30 to 60 seconds. Cut off a 2 to 3in (5.1 to 7.6cm) piece of duct tape (or other sturdy, sticky tape). Fold over a small portion of an end to make a non-sticky handle, then rub the sticky surface of the tape over the adhesive residue. If there's any stickiness left over after using the duct tape, wipe it away with a cloth dipped in hot water or rubbing alcohol. Using light pressure, wipe the sticky spot with a nylon or melamine foam scrub pad, such as a Mr. Clean Magic Eraser. Soak it with water first and give it a go. If water alone doesn't remove the gunk, try adding a drop of dish soap or dab the pad with rubbing alcohol. Rub the sticky area with the scrub pad gently. Nylon and melamine foam scrub pads are mildly abrasive, so be careful not to scratch the surface of your laptop. A blow dryer can melt and loosen glue, but it should be one of the last methods you try. Set it to low or medium, and aim it at the gunk for about 30 seconds. Then see if you can get rid of the remaining residue using a cloth, putty knife, or credit card. Even though your computer is off and unplugged, you don't want to risk overheating it or damaging its internal parts. Stick to a low or medium setting, and use it in 30-second intervals to avoid getting your laptop too hot.
