Business Resources. Most of us have had to deal with some form of malware at one point or another, whether it be simple adware, spyware, or a more malicious trojan that severely affects operating system performance. Obviously, getting a virus is a huge annoyance, and aside form putting your computer's performance and stability at risk, it can also pose a serious security risk if the virus is used by a hacker to gain access to your files and sensitive personal data.
As a computer "expert," one question people often ask me is "How can I download stuff without getting a virus? Is there a way to download something that has a virus attached to it, yet prevent your computer from getting the virus? Well, in this guide we'll show you a number of ways you can download just about anything and visit almost any website without fearing the consequences of encountering malware:.
Sandboxie Download3k mirror lets you run your web browser in an isolated environment on your machine. Any files that are downloaded by the browser are stored within a "sandbox" and cannot escape. To learn more about how Sandboxie can be used to protect your operating system from viruses, see their FAQ page on the topic. You can also check out our Introduction to Browsing with Sandboxie , or see the useful video tutorial below:.
Another way to isolate files from the rest of your operating system is to use a program like VirtualBox or VMware to install a virtual machine VM. This will give you an entirely separate operating system within your native OS, which is useful because most viruses that infect the virtual machine will not make it out to the host operating system.
Still, there are some network vulnerabilities that can allow some rare exploits to access the host OS. Thus, the best course of action is to use a virtual machine that is running a different operating system from your host OS. Likewise, malware designed for iOS or Android would most likely not be harmful to a Windows machine, so browsing within an Android or iOS emulator is another option.
If you decide to use this method, be sure to research possible exploits and extra precautions that need to be taken to secure a virtual machine. You could even run Sandboxie inside of a VM that is inside of another VM for multiple layers of protection. For this example, we'll call it XP Security Agent When you are prompted, use the arrow keys to highlight Safe Mode with Networking , and then press Enter.
Click the Start button and check whether the rogue security software appears on the Start menu. If it's not listed there, click All Programs and scroll to find the rogue security software's name.
Right-click the name of the rogue security software program, and then click Properties. In the Properties dialog box, check the path of the rogue security software program that is listed in Target. Note The folder name frequently is a random number. In the Program Files window, click Program Files in the address bar.
Scroll until you find the rogue security software program folder. For example, XP Security Agent Go to the Microsoft Safety Scanner website.
If you suspect that your computer is infected with rogue security software that was not detected by using Microsoft security solutions, you can submit samples by using the Microsoft Malware Protection Center submission form. Microsoft Defender Offline is an anti-malware tool that helps remove difficult to eliminate viruses that start before Windows starts.
Starting with Windows 10, Microsoft Defender Offline is built-in. Click Download the 32 bit version or Download the 64 bit version , depending on which operating system that you are running. If you're unsure of which operating system that you are running, see Is my PC running the bit or bit version of Windows. When you are prompted, press a key to select an option to use to start your computer, such as F12, F5, or F8, depending on the kind of computer that you are using.
Use the arrow key to scroll to the drive where you installed Microsoft Defender Offline file. Microsoft Defender Offline starts and immediately scans for malware. Confirm that the Windows firewall is turned on. See Turn Microsoft Defender Firewall on or off for instructions on how to do that on modern versions of Windows.
In the Search box, type firewall, and then click Windows Firewall. In the left pane, click Turn Windows Firewall on or off you may be prompted to enter your administrator password. Only download programs from sites that you trust.
If you're not sure whether to trust a program that you want to download, enter the name of the program into your favorite search engine to see whether anyone else has reported that it contains spyware. Read all security warnings, license agreements, and privacy statements that are associated with any software that you download.
Never click "Agree" or "OK" to close a window that you suspect might be spyware. Be wary of popular "free" music and movie file-sharing programs, and make sure that you understand all the software packaged with those programs.
Use a standard user account instead of an administrator account. An administrator account can access anything on the system, and any malware run with an administrator account can use the administrator permissions to potentially infect or damage any files on the system.
