How Can I Prevent Phone Viruses?
There’s a lot you can do to prevent your phone from getting a virus.
Stay up to date. Download and install a reputable antivirus app for your phone. Additionally, always agree to operating system updates. Download and use these apps before you think you need them. In addition to detecting viruses, they can protect your phone from getting them in the first place. Use approved apps only. Be sure to only download approved apps from Google Play for Android devices and the App Store for iOS devices. To make sure you’re getting a quality app, read the reviews, and check out the developer’s website. Be inbox-savvy. Use the same email hygiene you employ when looking at messages on your computer. Be wary of attachments, and only open those from trusted sources. Use the same level of caution with links embedded in a message. Finally, be wary of messages that look like they’re from companies you do business with. Beware of phishing schemes. Many scammers send fake emails that look like they’re from legitimate companies. The emails often feature the telltale signs of slightly-off email addresses, poor grammar, and requests for you to “update your credit card information” or other phishing scams. Monitor texts. Maintain the same level of skepticism regarding text and social media messages, as well as ads. Trust your gut. If something seems “off” about any activity you’re doing on your phone, take a step back and ask yourself if proceeding is worth losing your phone’s functionality or some of the data it holds.
A Word About Viruses on iOS
The claim “iPhones can’t get viruses!” isn’t exactly true. Any iOS device is a computer and any computer can get a virus. However, if you haven’t jailbroken your iOS device, the chances you have a virus are low. If you search the App Store, you won’t find any apps with the title Anti-Virus (other than maybe a game or two). Apple’s iOS is designed such that App A can’t interfere with the space where App B is working. That goes for the entire operating system, so an app can’t search your iOS device for viruses because apps can’t reach every space. However, it is possible to download an app from the App Store that does more than it claims. Pay attention to the privileges any app requests. For example, most games don’t need access to your photos, camera, or microphone.
What a Computer Virus Actually Is
A virus when coding that self-duplicates after the device gets infected and then destroys data or tries to send itself to another device. Smartphones can get viruses, but they are rarer than other issues.
