In any given scenario, these freedoms must apply to whatever code we plan to make use of, or lead others to make use of. For instance, consider a program A which automatically launches a program B to handle some cases. If we plan to distribute A as it stands, that implies users will need B, so we need to judge whether both A and B are free. However, if we plan to modify A so that it doesn't use B, only A needs to be free; B is not pertinent to that plan.
PCMag's top pick for software to take control of other computers is TeamViewer. Almost everything you need is free: desktop sharing, file transfers, even chat with remote users. And the setup couldn't be easier. Take control of a PC over a Web connection and a Chrome browser (even in ChromeOS) with the TeamViewer extension. There is also a Windows app in the Microsoft Store and optional downloads to make installing TeamViewer on multiple PCs even easier—though it's only free for personal use.
Microsoft CEO Steve Ballmer stated in 2001 that "open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source." This misunderstanding is based on a requirement of copyleft licenses (like the GPL) that if one distributes modified versions of software, they must release the source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and Free Software is also a misunderstanding. There are several large companies, e.g. Red Hat and IBM, which do substantial commercial business in the development of Free Software.
Comodo does much more than the built-in option in Windows. As it should, it blocks attacks from outside, and it has a malware detector that's better than some antivirus systems. It also installs the Comodo Dragon hardened security web browser. (Be careful during install, though; nice as it is, it may try to change your browser home page and search engine defaults.)
It's not going to outpace the paid anti-malware tools for effectiveness, but the easy-to-use Panda is more than capable of keeping up with the freebies. It will even automatically check USB drives you insert and launch a "vaccination" against launched processes on the USB drive. Just watch out during Panda installation as it tries to reset some of your defaults—the price you pay for "free."
