Signs Your Phone Has a Virus and How to Remove It Safely

 

In today’s world, our phones are more than just communication devices — they’re essential for work, banking, shopping, and staying connected. That makes it all the more alarming when a device begins to behave strangely. 

One possible cause? A virus. Mobile malware can sneak into your phone through suspicious links, shady apps, or compromised websites, and can create problems ranging from poor performance to data theft and financial loss. There are several red flags that suggest your phone might be infected. A rapidly draining battery could mean malicious software is operating in the background. Overheating, sluggish performance, frequent app crashes, or screen freezes may also be signs of trouble. You might notice strange new apps that you don’t remember installing or unexpected spikes in mobile data usage. 
In some cases, your contacts could receive strange messages from you, or you might find purchases on your accounts that you never made. If your phone shows any of these symptoms, quick action is essential. 

The first step is to scan your device using a trusted antivirus app to locate and remove threats. Check your device for unfamiliar apps and uninstall anything suspicious. You should also notify your contacts that your device may have been compromised to prevent the spread of malware through messaging apps. Updating your passwords should be your next priority. Make sure each password is strong, unique, and ideally protected with two-factor authentication. After that, review your online accounts and connected devices for signs of unauthorized activity. Remove unknown devices from your phone account settings and confirm your personal and security information hasn’t been altered. 

Depending on your phone’s operating system, the process of virus removal can vary slightly. iPhone users can try updating to the latest iOS version and removing suspicious apps. If the problem persists, a factory reset might be necessary, though it will erase all stored data unless a backup is available. While iPhones don’t include a built-in virus scanner, some reliable third-party tools can help detect infections. For Android users, antivirus apps often offer both detection and removal features. Rebooting the device in safe mode can temporarily disable harmful third-party apps and make removal easier. Clearing the browser cache and cookies is another useful step to eliminate web-based threats. 

If all else fails, a factory reset can clear everything, but users should back up their data beforehand. Preventing future infections comes down to a few key practices. Always download apps from official stores, keep your operating system and apps updated, and limit app permissions. Avoid clicking on links from unknown sources, and monitor your phone’s performance regularly for anything out of the ordinary. 

Whether you use Android or iPhone, dealing with a virus can be stressful — but with the right steps, it’s usually possible to remove the threat and get your phone back to normal. By staying alert and adopting good digital hygiene, you can also reduce your chances of being targeted again in the future.

Zero Trust Endpoint Security: The Future of Cyber Resilience

 

The evolution of cybersecurity has moved far beyond traditional antivirus software, which once served as the primary line of defense against online threats. Endpoint Detection and Response (EDR) tools emerged as a solution to combat the limitations of antivirus programs, particularly in addressing advanced threats like malware. However, even EDR tools have significant weaknesses, as they often detect threats only after they have infiltrated a system. The need for a proactive, zero trust endpoint security solution has become more evident to combat evolving cyber threats effectively. 

Traditional antivirus software struggled to keep up with the rapid creation and distribution of new malware. As a result, EDR tools were developed to identify malicious activity based on behavior rather than known code signatures. These tools have since been enhanced with artificial intelligence (AI) for improved accuracy, automated incident responses to mitigate damage promptly, and managed detection services for expert oversight. Despite these advancements, EDR solutions still act only after malware is active, potentially allowing significant harm before mitigation occurs. 

Cybercriminals now use sophisticated techniques, including AI-driven malware, to bypass detection systems. Traditional EDR tools often fail to recognize such threats until they are running within an environment. This reactive approach highlights a critical flaw: the inability to prevent attacks before they execute. Consequently, organizations are increasingly adopting zero trust security strategies, emphasizing proactive measures to block unauthorized actions entirely. Zero trust endpoint security enforces strict controls across applications, user access, data, and network traffic. 

Unlike blocklisting, which permits all actions except those explicitly banned, application allowlisting ensures that only pre-approved software can operate within a system. This approach prevents both known and unknown threats from executing, offering a more robust defense against ransomware and other cyberattacks. ThreatLocker exemplifies a zero trust security platform designed to address these gaps. Its proactive tools, including application allowlisting, ringfencing to limit software privileges, and storage control to secure sensitive data, provide comprehensive protection. 

ThreatLocker Detect enhances this approach by alerting organizations to indicators of compromise, ensuring swift responses to emerging threats. A recent case study highlights the efficacy of ThreatLocker’s solutions. In January 2024, a ransomware gang attempted to breach a hospital’s network using stolen credentials. ThreatLocker’s allowlisting feature blocked the attackers from executing unauthorized software, while storage controls prevented data theft. Despite gaining initial access, the cybercriminals were unable to carry out their attack due to ThreatLocker’s proactive defenses. 

As cyber threats become more sophisticated, relying solely on detection-based tools like EDR is no longer sufficient. Proactive measures, such as those provided by ThreatLocker, represent the future of endpoint security, ensuring that organizations can prevent attacks before they occur and maintain robust defenses against evolving cyber risks.

Overreliance on Detection Solutions in Security Stacks

 


The typical approach to detection used by organizations is to employ a variety of methods, such as antivirus software, sandbox engines, extensive data analysis, and anomaly detection, among others. This depends on the organization. Through monitoring and spotting, these technologies seek to discover and eliminate any malicious code or malware that might reach an endpoint and be executed by it. 

The only way to believe in the effectiveness of detection solutions is to see them in action. In the absence of detecting a threat, how are you supposed to know whether it is a threat or not? This is a fundamental principle that defines the foundation of such technologies. After the detection of a threat on the network, this involves searching for it, taking action against it, and moving to isolate and neutralize it. This is done as soon as the threat is confirmed. There are several problems associated with this approach.  

A detection solution is generally focused on identifying what is malicious and benign, which results in them having similar limitations as viruses. These methodologies can indeed produce false positives and negatives. Layering these technologies on top of each other can be very expensive. 

It is also imperative to note that relying solely on detection puts you at a disadvantage. It is this situation that forces you to respond to threat actors once they are already on the network - by the time you can react, the damage has already been done and it is nearly too late. 

Taking a Multifaceted Approach to Security 

Several typical defense mechanisms form the pillars of many organizations' security strategies. These include file inspections performed by SWGs and sandboxes to network and HTTP inspections, indicators of compromise feeds, and malicious link analysis. When confronted with HEAT, many of these defense mechanisms become virtually useless when confronted. 

The most effective way for organizations to be prepared to combat modern threats is to move beyond sole reliance on detection solutions. Instead, they should develop a multifaceted approach to security that brings multiple levels of protection. Even though these solutions still serve a purpose today, to ensure that attackers are prevented from even reaching networks in the first place, these solutions must be coupled with a proactive approach that focuses on prevention. 

Contrary to a detection solution, a prevention solution does not diagnose the quality of traffic. In other words, these companies take a zero-trust approach, that is to say, they assume that all traffic carries at least some level of risk in it. In this case, all traffic, up until it is proven to be innocent, is treated as guilty. Remote browser isolation (RBI) is an innovative method that prevents code from entering users' browsers without determining whether it is infected. This creates a digital air gap and allows users to browse the internet safely as RBI moves the execution point to a cloud-based container, preventing any malicious content from executing successfully. 

All traffic is executed in the cloud, so it never needs to be analyzed or remediated at the endpoint. This dramatically reduces the cost and time associated with managing your SOC.  

With HEAT techniques, attackers are not restricted to exploiting or bypassing vulnerabilities on the endpoint. The network is protected by preventing content from reaching it.
