🚨 Warning Signs Your PC Might Be Infected
Before jumping into the detailed process of how to remove virus from PC manually, it’s important to recognize the red flags that may indicate your system is infected. Many viruses are designed to operate in the background, silently collecting data or corrupting your system without immediately showing obvious signs. However, most malware eventually causes performance issues or strange behavior that can’t be ignored.
Here are some of the most common warning signs that your PC may be compromised by a virus or malware:
1. 🔻 Sudden and Unexplained System Slowdowns
If your computer has recently become sluggish—taking longer than usual to boot up, launch programs, or open files—it could be due to a malicious process running in the background. Viruses often consume CPU and RAM resources, leading to decreased performance.
2. 💥 Frequent Freezing or Crashing
Are programs randomly crashing or your system freezing without warning? While this could be due to hardware or software conflicts, it’s also a major sign of malware activity. Some viruses intentionally destabilize your PC to damage files or make it harder for you to use tools that could remove them.
3. 🪟 Endless Pop-up Ads and Browser Redirects
If your browser is suddenly bombarded with pop-ups, fake warnings, or you’re being redirected to strange websites, you’re likely dealing with adware or a browser hijacker. These types of malware generate revenue for attackers through fraudulent ad clicks—and can lead to more dangerous infections.
4. 💽 Unusual Hard Drive Activity
Is your hard drive light constantly blinking—even when you’re not doing anything? Viruses and spyware often run silently, scanning your system or transferring data in the background. Unusual disk activity is a major red flag you shouldn’t ignore.
5. 🛑 Disabled Antivirus or Firewall Protection
Some advanced malware programs can disable your antivirus software or block you from accessing security websites. If you find your antivirus turning off unexpectedly, or Windows Security says your firewall is off when you never disabled it, it’s a sign you’re dealing with a serious infection.
6. 📂 Unknown Programs Launching on Startup
Have you noticed strange programs launching every time you boot your PC—especially ones you don’t recognize or remember installing? Malware often adds itself to your startup list so it can run every time your system starts, ensuring it stays active.
7. 📧 Strange Emails or Messages Sent From Your Account
If your contacts are receiving suspicious messages or spam from your email or social media accounts, malware might have gained access to your credentials. This behavior is often seen with keyloggers or Trojan horse viruses that capture keystrokes and login details.
8. 🔐 Locked Files or Ransom Demands
If you’re suddenly unable to open certain files and see strange extensions or ransom messages demanding payment to unlock them, your system may be infected with ransomware—one of the most dangerous forms of malware.
Recognizing these symptoms early can make a huge difference in protecting your files and recovering your system. If you’re experiencing one or more of the above warning signs, it’s time to take action—and fast. While antivirus tools are helpful, they’re not always reliable when dealing with new, complex, or hidden threats.
That’s why this guide will show you how to remove virus from PC manually, giving you full control over the cleanup process and helping you eliminate malware that your antivirus might miss.
Let’s move on to the step-by-step manual removal process.
🔧 Step-by-Step: How to Remove Virus from PC Manually
Now that you’ve identified potential signs of a malware infection, it’s time to take back control of your system. Below is a step-by-step manual virus removal guide to help you clean your PC without relying solely on antivirus software. Whether your system is behaving strangely or you’ve detected a specific threat, follow these steps carefully.
✅ Step 1: Boot into Safe Mode
Safe Mode loads Windows with only the most essential drivers and processes, making it easier to isolate and remove malware without interference. Many viruses are designed to launch automatically at startup, so entering Safe Mode prevents them from doing so.
For Legacy Systems (Windows 7 or older):
Restart your PC.
Immediately start pressing F8 or Shift + F8 repeatedly before Windows begins to load.
On the Advanced Boot Options screen, select Safe Mode or Safe Mode with Networking using the arrow keys.
For Windows 10/11:
Click on Start > Settings > Update & Security > Recovery.
Under Advanced Startup, click Restart Now.
Choose Troubleshoot > Advanced Options > Startup Settings > Restart.
Once your PC restarts, press 4 (or F4) to start in Safe Mode or 5 (F5) for Safe Mode with Networking.
✅ Now that you’re in Safe Mode, malware processes are less likely to run—giving you a safer environment to work in.
🛑 Step 2: End Suspicious Processes via Task Manager
Now let’s hunt for malicious processes that might still be running.
Press Ctrl + Shift + Esc to open Task Manager.
Click on the Processes tab and look for:
Unfamiliar names
High CPU or memory usage
Misspelled versions of legit processes (e.g.,
explorrer.exe)
Right-click on a suspicious process and choose Open File Location.
Legitimate Windows processes are usually located in
C:\Windows\System32.
If the file is located elsewhere or looks shady, right-click the process and select End Task.
Then manually delete the file from its location.
⚠️ Don’t delete system files unless you’re sure—they could crash your system.
🧹 Step 3: Uninstall Unknown or Malicious Programs
Malware often disguises itself as legitimate-looking software or installs silently without your knowledge.
Go to Control Panel > Programs > Programs and Features.
Sort the list by Installation Date.
Look for programs you don’t recognize, especially those installed recently.
Watch out for names like “System Optimizer,” “Driver Helper,” or random gibberish.
Right-click the suspicious program and choose Uninstall.
🧠 If you’re unsure about a program, do a quick search to check if it’s malware or legitimate.
🗑️ Step 4: Delete Temporary Files
Temporary folders are a common hiding spot for malware scripts and installation files.
Press Win + R, type
%temp%, and hit Enter.Press Ctrl + A to select everything and then Delete.
Also, visit
C:\Windows\Tempand delete all contents there.Finally, empty the Recycle Bin to completely remove the deleted files.
💡 Clearing temp files not only removes malicious scripts but also improves system performance.
🚫 Step 5: Disable Suspicious Startup Programs
Many viruses are designed to auto-run every time you boot up your PC. Disabling them at startup breaks their persistence.
Open Task Manager (Ctrl + Shift + Esc) and go to the Startup tab.
Disable any suspicious or unknown entries.
Check the publisher column—if it’s blank or unfamiliar, it’s worth investigating.
For older Windows systems:
Press Win + R, type
msconfig, and press Enter.Go to the Startup tab and disable unwanted programs.
🧠 If you’re unsure whether a startup item is harmful, search its name online before disabling.
⚙️ Step 6: Use Command Prompt to Track and Remove Malware
For more advanced users, Command Prompt offers powerful tools to dig deeper.
Press Win + R, type
cmd, and press Enter to open Command Prompt.Type the following command:
This displays all active connections along with the executables responsible.
Look for any:
Unknown remote IP addresses (especially from suspicious countries)
Processes tied to unexpected or hidden applications
If you identify a suspicious process, trace its file path and manually delete the
.exeor.dllfile from your system.
⚠️ Be cautious when deleting files in system directories—always double-check legitimacy first.
🌐 Step 7: Reset Your Browser to Remove Hijackers
Browser hijackers can redirect your searches, bombard you with ads, or collect your data.
🔹 Google Chrome:
Go to Settings > Reset and clean up > Restore settings to their original defaults
Confirm and reset
🔹 Mozilla Firefox:
Click the menu (☰) > Help > More Troubleshooting Information
Click Refresh Firefox
🔹 Microsoft Edge:
Go to Settings > Reset Settings > Restore settings to their default values
✅ This removes extensions, search engine changes, and malicious startup URLs injected by malware.

🧰 Using File Explorer for Deeper Inspection
🔍 Dig Deeper: Manually Investigating Malware in Your File System
If you’re comfortable navigating your computer’s directories and inspecting file properties, there’s another layer of malware hiding in plain sight—your file system. Sometimes, viruses won’t show up in Task Manager or startup entries but still reside in hidden folders, running silently in the background.
This method gives you a chance to track down such files manually. It’s more advanced but incredibly effective if you know what to look for.
📂 Step-by-Step: Investigating Suspicious Files in Your System
📁 1. Open the Hidden Temp Folder
Navigate to the following path in File Explorer:
If you don’t see the AppData folder, it’s because it’s hidden by default. Enable it by clicking View > Show > Hidden Items in File Explorer.
🧠 Why Temp?
This folder is a common dumping ground for malware payloads, hidden installers, scripts, and temporary executable files used during infection.
🗂️ 2. Sort Files by “Date Modified”
Once inside the Temp folder, sort the files by “Date Modified.” This brings the most recent activity to the top, helping you spot newly created or dropped files from suspicious activity.
Focus your attention on:
.exe(executable).dll(dynamic link library).bator.vbs(scripts)Randomly named folders that recently appeared
👀 Files that appeared around the same time your computer started acting strangely should be viewed with extra caution.
🧾 3. Inspect Each File’s Properties
Right-click any file that looks suspicious and select Properties, then go to the Details tab.
🔍 Red Flags to Look For:
Blank or missing file descriptions
No company name or publisher info
Misspelled names (e.g.,
Microsofft Corp.instead ofMicrosoft Corporation)Fake or generic icons
Creation dates that don’t match your system activity
📌 Legitimate system files almost always include proper metadata, company signatures, and consistent naming.
🌐 4. Scan Unknown Files with VirusTotal
Before you delete anything, it’s best to confirm your suspicion.
Upload the suspicious file
Let it scan using 70+ antivirus engines
🧠 If the file is flagged by multiple scanners, it’s highly likely to be malware.
Do not open or double-click suspicious files—only upload them directly from File Explorer.
🧹 5. Delete Confirmed Malware Files
Once you’ve confirmed a file is malicious (or highly suspicious), right-click and delete it.
Then empty your Recycle Bin to fully remove it from your system.
To be extra cautious, consider running Disk Cleanup or a third-party tool like CCleaner to clean remaining temp files and residual traces.
⚠️ Important Notes:
Never delete files unless you’re sure they are not critical system components. When in doubt, research the filename online or consult a technician.
Some malware may restore itself after deletion if there’s a startup entry or service still pointing to it. Make sure you’ve disabled those in earlier steps (Task Manager, Autoruns, msconfig).
Deleting malware doesn’t guarantee full system recovery—always scan your system afterward and reset passwords if you suspect a breach.
💡 Final Thought:
Digging into system folders manually isn’t for everyone, but if you’re tech-savvy and willing to look under the hood, it can be one of the most effective ways to find malware that’s hiding in plain sight. When paired with tools like VirusTotal and a sharp eye, it becomes a powerful part of your virus removal toolkit.
