Keeping your browser up to date ensures the latest security fixes are active while you browse the web. Many modern browsers will update themselves in the background as they become available. Chrome users can go to "Menu > Settings > About" to update. Chrome will also flag suspicious files when they are downloaded with a prompt if you want to keep it. If you are ever unsure, choose "Discard". Firefox users can go to " >? > About Firefox" to update. Safari users can update by opening the App Store and clicking the "Update" tab. Microsoft will now update Internet Explorer/Edge automatically. Those using an OS older than Windows 10 can go to "Control Panel > Windows Update" to download the latest updates for Windows and Internet Explorer. Updating your OS ensures that you have the latest security fixes for your device. Although this is not a foolproof solution to risky downloads, it will help secure your computer against potentially malicious files. Android users can go to "Settings > About > System Updates" to check for the latest software available for the device. Keep in mind that availability of system updates can vary depending on the mobile carrier and age of the device. iOS users can go to "Settings > General > Software Update" to check for the latest software. Older devices may not be compatible with the latest OS updates. Mac OS users can open the "App Store" and select the "Updates" tab. On older versions, or if the App Store is unavailable, you can also go to "Apple Menu > Software Update". Windows 10 downloads and installs updates automatically (this feature can't be disabled). Users of older versions can go to "Control Panel > Windows Update". Torrent sites are a tempting resource for videos, but can often contain malicious files. Furthermore, you can never really be sure if the file you are downloading is what it says it is until you open it. If you choose to use file-sharing programs, make sure you have a virus scanner installed to check your files before you open them. There are many choices for video downloader programs. Look for well rated and highly downloaded applications. Open source software is often a safe bet. Most programs that are open source will mention it on their product page. If you use a browser that supports extensions, such as Chrome, use the "store" to search for free downloader extensions. These will often have a collection of ratings of quality and popularity and their installation is limited to your browser environment. The most reputable sources for videos, such as the iTunes store, Play Store, or Amazon will cost money. If you want to download from free sites, use well-recognized names like YouTube or Vimeo. Downloading videos from YouTube is a relatively safe bet, since it is unlikely to be carrying malware and you can view any video before you download it. You should use greater caution when acquiring a downloader program. Make sure the source of the download is reliable, and that the software itself is reputable. Some sites that sell TV/Movies also sometimes have free offerings. For example Google Play has a number of episodes (and sometimes full movies) offered for free. You will need a Google account to watch, and they can be downloaded to a mobile device with the Google Movies] App. Browsers like Firefox and Chrome will block sites that are known to carry malware. You will see a full-page notification when this happens. If you are on the fence about a site's reliability, do a little preliminary research on Google.

summary: Make sure your web browser is up to date. Make sure your operating system is up to date. Avoid file-sharing websites and programs. Choose software that seems trustworthy. Download only from trusted sources.

Summarize the following:
Start by working in your local film scene or in areas that you can easily get to. Save the money you make so you can make the move to a larger city where more roles are available and movies are frequently made. Consider moving to Los Angeles, Austin, New York, or Atlanta if you're in the United States. Try Vancouver, Toronto, London, or Mumbai for film outside of the US. Search for casting calls on websites like Backstage or Craigslist for local commercials. As you go in for the audition, dress for the part you're playing so the casting directors can easily picture you in the role. Commercial acting is a smaller role, but it will give you exposure to a wide audience and get your face out to the public. Look out for posts on Craigslist that seem too good to be true since they could possibly be scams. Watch for off-site emails or jobs that seem to be paying too high with no needed experience. Once you're where you need to be, get connected and take on roles as an extra, or background actor. Open casting calls for these can be found all over the Internet, but a few places to start off are Backstage, Hollywood Reporter and Variety. Though it may not be a starring role, you can still list an extra role on your resume to show you have experience. Ask around your network for opinions on who to go to and how to get started. Make cold-calls or send inquiry letters to agencies to see if they are looking for new talent to represent. An agent will help you negotiate deals for the roles you take on. Agents only get paid when they find you work. Don't buy into the ones that demand some exorbitant fee even if your schedule stays wide open. Look into organizations like ACTRA, AEA, AGMA or AGVA. Once you are a member for at least 1 year and worked under union, you're eligible to get into SAG (the Screen Actor's Guild). Unions provide you with benefits and insurances while you're working. Annual SAG fees are $201.96 USD and 1.575% of the earnings you make in that year. Check with the union you're interested in to see what their annual rates are. Though it's completely possible to run through all the hoops without it and still find success, having your equity card opens up a number of auditions that otherwise wouldn't be available to you. You either have to get a contract that requires equity standing, be a member of a sister group (like SAG, for example), or accumulate enough credits to meet the standard. It's natural to find the process a bit confusing, so contact a friend or mainstay in your actor's social network for more information on how they received their card.
summary: Move to a large city if possible. Look for roles in commercials when you begin. Become an "extra" actor in larger pictures. Get an agent. Get into a performer's union. Consider getting your equity card if you want to do theatre.
