– Don’t use public USB charging stations
– Set up remote wipe in case your phone is lost or stolen
– Backup data regularly in case a factory reset is needed
Removing Pre-Installed Malware
Some new phones have been found to contain malware installed right from the factory. Here’s how to remove it:
– Check online forums for issues with your phone model
– If pre-installed malware is confirmed, download an antivirus app
– Run a full system scan to detect and remove any infected apps
– Perform a factory reset to wipe the phone and reinstall the OS
– Opt out of reinstalling any manufacturer bloatware when setting phone back up
– Download apps only from Google Play or other trusted sources
– Replace compromised apps like the browser or text messaging with trusted alternatives
Can You Get a Virus by Visiting a Website?
Yes, it is possible for malware to infect your phone simply by visiting a compromised website, in what’s known as a drive-by download attack. Here’s how it happens:
– You click a link to a website that has been hacked
– The site runs an exploit kit searching for vulnerabilities
– If your browser or apps are out of date, it can leverage flaws to silently install malware
– The virus is now on your phone and can begin causing damage
To avoid drive-by downloads:
– Keep your browser and apps fully updated at all times
– Avoid clicking links from untrusted sources
– Stick to sites that use HTTPS encryption
– Use a reputable antivirus app to scan apps and memory
– Disable automatic file downloads in your mobile browser
Drive-by virus attacks take advantage of unpatched software to infect devices without the victim doing anything overtly suspicious like downloading a file. To stay protected, keeping your phone’s apps patched is critical.
Can You Get a Virus from the Play Store?
The Google Play Store offers millions of Android apps, most of which are safe. However, it is possible for malware to occasionally sneak into even this official app store. Some ways this can occur include:
– Developer uploads a legitimate app that later has malware added via an update
– App pretends to be something useful but actually contains malicious code
– Copycat apps mimic popular apps with malicious versions
– Apps take advantage of permissions for malicious actions
No app store is perfect at keeping out all malware, which is why caution is still warranted:
– Read app reviews and only download from trusted developers
– Avoid “too good to be true” apps like free money scams
– Check the app permissions and don’t install if overly invasive
– Run periodic antivirus scans even on Google Play downloads
– Report suspicious app activity to Google for investigation
While the Play Store offers a decent level of protection, it cannot prevent all malware, so users still need to exercise caution.
Can You Get a Virus from an App You Trust?
In some cases, yes. Even apps you already have installed and trust can become infected over time, especially if they are not diligently kept up to date:
– Trusted apps can contain newly discovered vulnerabilities that are exploited if left unpatched.
– Apps can have malware introduced via malicious updates that sneak past screening.
– Your apps connect to remote servers, which could be compromised down the line and serve malware.
– Links within apps could point to sites that later end up hacked to distribute viruses.
No app has perfect long-term security. Steps you can take include:
– Enable automatic app updates so patches are always installed
– Periodically scan trusted apps with an antivirus tool
– Monitor app reviews for signs of a problem like crashes or suspicious permissions
– Revoke permissions from apps that seem overly intrusive for no reason
– Use a VPN to encrypt traffic which adds an extra layer of security
While it’s rare, even use of trusted apps carries some inherent security risks over time. Staying vigilant is important.
Can You Get a Virus from the Apple App Store?
The Apple App Store is generally very secure and malware is extremely rare. However, there have been a handful of cases where infected apps slipped through:
– Copycats impersonating real apps with malicious code
– Legitimate apps later hacked to add viruses via updates
– “Jailbreak” apps containing malware intended to root devices
– Legal spyware apps abusing permissions for illicit data harvesting
Apple’s tight control over iOS apps makes viruses getting into the App Store very unlikely. However, not impossible:
– Avoid jailbreaking your device as this disables security measures
– Read reviews and stick to established, trustworthy developers
– Check app permissions and beware anything suspicious
– Keep your device’s iOS version updated to the latest version
– Use trusted antivirus apps like Norton to scan for iOS malware
While extremely rare, even the App Store isn’t perfect, so continue exercising caution when downloading apps.
Can You Get a Virus from Wi-Fi?
Public Wi-Fi networks can potentially expose you to viruses in a few ways:
– Unsecured networks allow criminals to spy on traffic and launch attacks.
– Fake hotspots pretend to be legit to trick users into connecting.
– Infected network equipment itself can spread malware to connecting devices.
Some steps you can take for protection:
– Avoid doing any sensitive online activities like banking over public Wi-Fi.
– Confirm the network name matches the advertised name before connecting.
– Use a VPN app to encrypt traffic even on public networks.
– Turn off auto-connecting to Wi-Fi and mobile hotspots when not needed.
– Use mobile data instead of public Wi-Fi whenever possible.
– Keep antivirus software installed and do periodic scans after using Wi-Fi.
In general it’s better to avoid public Wi-Fi altogether when you can. Use trusted VPNs or your phone carrier’s mobile data for more secure online use.
Can You Get a Virus from Downloading Files?
Yes, one of the most common ways phones can get infected is by downloading malicious files:
– Infected apps from third-party app stores
– Email attachments containing viruses
– Fake “security updates” tricking users into downloading
– Coronavirus maps, porn, or other shady downloads
To avoid viruses from downloads:
– Don’t enable installation from “unknown sources”
– Install apps only from official app stores like Play Store
– Don’t open attachments from unverified senders
– Beware downloads promoting “big prizes” or other scams
– Have antivirus scan new app installs before launching them
– Turn off automatic file downloads in your mobile browser
Just because a file can be downloaded does not mean it’s safe. Stay vigilant with downloads to avoid malware infections on your phone.
What Should You Do if Your Phone Has a Virus?
If your phone shows signs of malware infection, here are the steps to take:
1. Install antivirus software if you don’t have it already. Run a scan to detect and remove any infections.
2. Check running apps and stop anything unfamiliar or suspicious. Viruses often show up as strange-looking apps.
3. Uninstall any malicious or questionable apps immediately. Don’t launch them.
4. Reset your device to factory settings if the issue is serious. This wipes the phone and reinstalls a clean OS.
5. Change all passwords from another device in case they were compromised.
6. Notify contacts you interacted with from the infected phone in case their devices are now also exposed.
7. Learn from the experience! Going forward, avoid downloads from unverified sources, use trusted Wi-Fi, install antivirus apps, and keep software patched.
Virus infections happen, but following good security practices minimizes your risk. Act quickly to remove malware and undo any potential damage.
