You might be using your computer one day and notice that there’s some weird behavior occurring.
Maybe, it’s the random popups or system crashes, strange warnings or dialog messages, excessive network activity, and programs start misbehaving (randomly opening, crashing, or strange error messages), you might be infected with malware.
Here are some basic steps that you can take to remove the malware. Note, you are responsible for your own data so please be sure to perform any backups before attempting any malware removal.
These suggestions are not effective on all types of malware (crypto and others), and you should seek professional advice/help for serious infections.
What is malware?
‘Malware‘ is an umbrella term used to refer to a variety of forms of hostile or intrusive software including computer viruses, worms, trojan horses, ransomware, spyware, adware, scareware, and other malicious programs. It can take the form of executable code, scripts, active content, and other software. Source.
How do you get infected by malware?
Usually, it can be very difficult to determine the cause of infection. Take care to inspect any file or link before running/clicking on it when browsing the internet, and avoid unsafe websites which can contain exploits.
Don’t give permissions to unknown programs to run and make sure to keep programs updated – developers will patch exploits and other vulnerabilities through updates.
These steps can be run in normal mode without booting into safe mode. These steps assume that you can boot your computer normally without issues.
Run rkill (download and run). This will kill running malware processes, fix and repair your registry and other file extensions. Do not reboot after running this.
Download and run Malwarebytes Anti Malware. Set these settings and run the scan. It will repair damage done and remove most malware.
Then, run AdwCleaner. Scan first, then clean any infected results. It’ll prompt you to reboot after successful cleaning. This will remove malware on your system.
To prevent future infections, make sure to avoid opening files you might not know the source of and visiting websites that don’t appear legitimate.
Obviously, its not always possible to avoid infection especially if a website you regularly visit gets compromised, but you can follow these simple steps to remove the malware!
While running Android Studio, you can instantly connect an Android device via USB on Mac or Linux, and run a developing app on that device. What about Windows? For Windows, you’ll need to install the Google USB Driver before running your developing app on your Android device, phone, or tablet.
Open Android Studio, open the SDK Manager, and install the Google USB Driver.
Search and open Device Manager.
Find and expand Other devices section.
Right click the device name (i.e. Nexus 5) and select Update Driver Software.
Browse my computer for driver software and click Next.
Browse for the Google USB driver folder and click next to install the driver.
Connect your Android device to the PC. Easy enough. Plug your Android device via USB to your PC.
Open Android Studio, open the SDK Manager, and install the Google USB Driver. The SDK Manager can be opened by the following Android Studio icon:
Click on Android SDK. Check off the Google USB Driver and hit OK to install.
Search and open Device Manager. You can use Windows search to find the Device Manager.
Find and expand Other devices section. Right click the device name (i.e. Nexus 5) and select Update Driver Software.
Browse my computer for driver software and click Next. Browse for the Google USB driver folder and click next to install the driver. The Google USB driver folder should be inside your C:\Users\*username*\AppData\Local\Android\sdk\extras\google\usb_driver\.
After installing, when running Android studio, you should be able to run any developing app project on your Android device. When you hit the play button on Android Studio, a prompt should pop up and ask what connected or virtual device you want the app to be run on. Select the connected Android device, phone, or tablet and voila! You will need to unlock your Android device to see the app immediately be run.
Windows 10 is the next best thing coming from Microsoft. Here’s a few things to keep in mind when you’re considering the switch.
Windows 10 is free for most people – but if you’re running Windows 7 or Windows 8.1. Don’t worry, you have one year, until July 29th, 2016 to make the jump. If you miss out on the free upgrade for whatever reason, it’ll cost $119. To upgrade your existing installation, look for the windows icon in your notification bar – and enroll
Once the update is available for your system, it’ll prompt you to install. If you need to, you can put it off until you’re ready to make the switch. It can take a few days as Windows 10 is rolled out to all users, so don’t despair if it doesn’t appear immediately for you. If you’ve been regularly updating windows and the icon doesn’t appear for you, simple, just visit this link to do it manually.
During the reservation process, Windows will let you know if you have any incompatible hardware – make sure to install any updates for your devices beforehand so that you can use them with windows 10.
Windows 10 can be installed without you having to lose any files or settings! Some things will change and require reconfiguration, but if you’re coming from Windows 8.1 or Windows 7, everything should remain as you had it beforehand. After the upgrade, if you want to do a complete reinstall you’ll have the option for that as well. Just make sure you have your Windows Serial Key handy (if you lost it, use this script or Ultimate PID Checker to grab it from your system) and create a bootable DVD or USB.
Windows 10 brings a number of performance tweaks and other optimizations. If you’re using a graphics card, you’ll be compatible with DX12 if you have a recent graphics card from Nvidia or AMD.
Defragment your hard drive before upgrading – defragging will optimize fragmented files and disk usage. You’ll be modifying a lot of files on your hard drive when performing the upgrade. For Windows 7, you can start Disk Defragmenter. On Windows 8.1, if you right click your hard drive in My Computer and go into Properties, you’ll have the option to run Disk Defragmenter as well.
You’ll also want to run “Disk Cleanup” and “Clean System Files,” which will remove all the crud that’s been building up in your computer and free up some space.
Security and Anti Virus/Malware
Windows 10 will come with its own anti-malware software, Windows Defender (originally Security Essentials). If you want to use your own, make sure to check for updates and other maintenance before starting the upgrade to make sure they’ll work in Windows 10.
Those are just a few overall changes to Windows 10 as an operating system from previous iterations. Go upgrade now!
There’s a few different techniques for screenshotting on Windows, starting with the ubiquitous PrintScreen button. This button is usually found above the Insert, Home, and Page Up Button on your keyboard, but this depends on the type of keyboard you have and may not even be its own dedicated button on laptops. If you don’t have easy access to the PrintScreen key, don’t worry, read on.
With the PrintScreen Key
Using the PrintScreen key, a simple press will screenshot your entire workspace, taking a snap of everything you’re looking at, including things on other screens if you have multiple monitors or if you’re hooked up to a projector. Your screenshot is saved to your clipboard, so you can easily paste it into anything that you’ll need. I like to put it in Paint, so I can quickly review it and even crop pieces out that aren’t relevant to the screenshot. However, if you’re doing that – there are better options.
Alt + PrintScreen
Pressing ALT and the PrintScreen key (PrtScn on some keyboards) will allow you to quickly grab a screen capture of the current window. Note that this means the current window that has focus, the window that you’re currently using. You can avoid any mistakes by selecting focus with ALT + TAB, or just simply clicking on the window. You can paste it into whatever you need, Paint is my preference.
Third and my favorite way to quickly grab a screenshot is using the snipping tool. This tool comes with all installations of Windows 7 and above, and allows you to quickly select what you want in your screenshot. Simply click on "New", and once your cursor changes into a cross, you can click and drag to select what’s going to be included in your screenshot. Once you release your click, you’ll be able to review the screenshot and save it wherever you need it.
That’s it! Easy choices for screenshots in Windows 7 and 8.
Cygwin provides the Linux feeling on Windows. With Cygwin, you can get a sizable Linux collection of GNU and Open Source tools including a terminal that supports POSIX interface on Windows.
Check whether your System type is 32 bit or 64 bit. If you have Windows 8 or 8.1, right click on This PC on your Desktop, then click on Properties. If you don’t have This PC on your Desktop, you can also use Windows’ search to look for “This PC“, then right click the icon, and click on Properties.
On the Properties of This PC, you can see the System Type underneath System category. For me, System type: 64-bit Operating System, x64-based processor. I have a 64 bit operating system.
Select the blue linked executable setup based on your system type of Step 1. Download will start automatically after clicking on one of the blue executable setup links.
Open the executable Cygwin setup file. Run the set-up as normal. Click on Next on the Cygwin Setup screen.
When choosing Installation Type, select Install from Internet (default). Click Next.
When choosing the Installation Directory, you can leave the root directory by default, which will be C:\cygwin64 (64 bit). Install for all users. Click Next.
The Local Package Directory contains the setup installation files for packages that you wish Cygwin to have. Underneath Select Local Package Directory, the default is the directory where you have the setup executable.
You can leave this by default.
For Setup your Internet Connection, use Direct Connection for your Internet Connection if you’re using wi-fi or ethernet. Click next.
Choose a Download Site. Select any of the download sites. Click Next.
You’ll now be at Cygwin Setup – Select Packages. From here, you can search for packages that you wish Cygwin to have. The ones that I recommend are:
gcc-core(Cfiles)-inside Devel category
make(makefiles)-inside Devel category
openssh(tousessh)-inside Net category
nano(text editor)-inside Editors category
For each of these packages, they belong to categories. Search for a package. Click on the + next to a category to expand the contents of the search. Click on the circle twirl with the arrows to select the most up-to-date version of that package. Package names are on the right with a short description of that package.
After selecting a version to install for all your packages, you can click the next button at the bottom right of the setup screen. At the Resolving Dependencies screen, make sure that the checkbox that says Select required packages (RECOMMENDED) is checked. Click Next. The download and installation of your desired packages will commence.
After you finish the download and installation, you can check Create an icon on Desktop. Click Finish. You’ll find a program called Cygwin64 Terminal on your desktop. Open the program. Cygwin is installed.
You can also add the Cygwin packages and POSIX interface for the Windows command prompt. In other words, you can make the command prompt act like the terminal in Linux.
Right click on “This PC” and click Properties if it’s on the Desktop. Also, you can use Windows’ search for “This PC” and right click, then click on Properties.
Click on Advanced System Settings in this Properties window.
In the System Properties that pops up, click on Environment Variables, which will be within the Advanced tab. Inside Environment Variables, look underneath the System variables section. Scroll through and look for the Variable with the name Path. Click on that line. Click on the Edit button underneath. For 64 bit, add a “;C:\cygwin64\bin;” to the end of the Variable value line. This allows the command prompt to work with Cygwin’s directory path to the Cygwin’s bin folder and utilize Cygwin’s packages and POSIX interface. Click OK for each of the three windows to save this setting.
Open a command prompt. You can use Windows’ search and search for command prompt or cmd. Click on command prompt, and a command prompt black box will open. You will have all the functionality of Cygwin within the command prompt. You can choose to use either Cygwin or a command prompt to use the linux tools or POSIX interface.
