As our digital footprint expands, so does the likelihood of encountering malicious software or a virus. This is particularly true for our smartphones, which have become an indispensable part of our daily lives. Mobile phones hold a wealth of personal information and data that can be lucrative to cybercriminals. Given this, it’s crucial to know whether your phone is infected and if so, how to effectively deal with the situation.In the course of this article, we will discuss the signs that may indicate that your phone has a virus, offer solutions for dealing with such a situation, and provide an overview of preventive measures to ensure the safety of your mobile device.  For comprehensive device protection, we recommend using McAfee+ for its robust security infrastructure.


Smartphones have become just as susceptible to malware as personal computers. Unbeknownst to many, mobile devices can suffer from symptoms that may not seem virus-related at first, but could actually be warning signs of an underlying issue. Some of these symptoms include but are not limited to: sudden increase in data usage, battery drain, continuous pop-up ads, slow performance, and unexplained charges on your billing statement.

The medium through which viruses infiltrate devices has also evolved. Be it through malicious apps, unsafe Wi-Fi networks, phishing emails or infected websites, these threats are omnipresent and ever-evolving. As a result, it’s key to constantly stay informed and vigilant.

Signs Your Phone May Have a Virus

While it may be intuitive to detect a virus on your phone, some are quite sophisticated and are designed to run invisibly in the background. Therefore, knowing what to look out for is a critical first step in preventing further damage.

Here are some signs that your phone might be infected:

Increase in data usage: A sudden increase in data usage can be an indication that a virus is running tasks or processes on your phone. Most malware works by sending data back to the hacker’s server, which can cause your data usage to spike unexpectedly.

Battery drain: Malware tends to use a lot of battery power because it runs continuously in the background. If your fully charged battery loses power quickly and for no apparent reason, you might have a virus on your phone.

Pop-up ads: While some pop-up ads are just annoying, others can be harmful. If you are seeing a multitude of unwanted pop-up ads on your smartphone, you may have been infected with adware, a type of malware that forces devices to view and interact with harmful ads.

Slow performance: If your phone is suddenly running significantly slower, crashing, or freezing, a virus may be the culprit. Malware typically uses up your phone’s resources, causing it to work harder and resulting in slow performance.

Unexplained charges: If you notice unexplained charges on your phone bill, particularly in the ‘SMS’ category, it’s possible that your phone is infected with malware. Some types of malware will send costly messages to premium-rate phone numbers.

How to Deal with a Virus on Your Phone

If you suspect that your phone is infected, it’s important to act quickly to prevent any further damage.

Here are several steps you can take to resolve the issue:

First, install a reliable mobile security app. There’s a wide array of mobile security apps available on the market, McAfee+ being a prominent one. These apps offer real-time protection against malware and viruses. They scan your phone for any malicious software and delete it accordingly. It’s also recommended to schedule regular scans to ensure ongoing protection.

Second, ensure your phone’s software is up-to-date. Regular updates are not only beneficial for gaining new features but also for improving security. Updates often include patches for security vulnerabilities that have been discovered. Therefore, keeping your phone updated will strengthen it against potential threats.

Third, be cautious of what you download and the sites you visit. Malicious apps and websites are common culprits for introducing malware. Only download apps from trusted sources, like Google Play Store or Apple App Store, and ensure you read the app permissions before installation. Additionally, avoid clicking on suspicious links in emails and text messages.

Lastly, consider performing a factory reset on your device. Although this should be your last resort due to the data loss, it will thoroughly wipe your phone and any viruses along with it. Make sure to back up any important data before going ahead with this step.

Preventing Future Infections

After successfully dealing with a virus, you’d certainly want to prevent another infection.

Here are some preventive measures you could take:

One key preventive measure is to only download apps from official app stores. Unofficial sources or third-party app stores often don’t perform the stringent security checks that official stores do. Therefore, downloading apps from them increases the odds of inadvertently downloading a malicious app.

Another extremely effective preventive measure is to install a reliable mobile security solution. As previously mentioned, this tool will provide real-time protection from potential threats. A notable security solution is McAfee+, which offers robust and comprehensive protection.

Thoroughly vetting your permissions is another preventive measure. Some apps request excessive permissions that they don’t actually need to function. Granting these permissions can put your personal data at risk. Hence, it’s wise to pay attention to the permissions an app is asking for and question if they are reasonable before granting them.

Finally, it’s important to maintain a culture of vigilance. Regularly updating your software, avoiding suspicious links, and keeping informed about potential threats can go a long way in protecting your phone.


Smartphones have become an integral part of our lives, storing a wealth of personal data. As such, they have become lucrative targets for cybercriminals. Knowing how to detect a virus, deal with it, and prevent future infections is vital for maintaining the health of your device and the safety of your data. Consider investing in a reliable security solution like McAfee+ for comprehensive protection. Remember, prevention is always better than cure, especially when it comes to digital security.
