10 Warning Signs That Your Computer is Malware Infected

Hence, in this article, we have decided to list some warning signs that show that your PC is malware-infected. If you feel related to any of these signs, you should run a full anti-malware scan on your PC.

1. Slowdown


Malware often tends to modify the files of your programs, browsers, etc. The very first sign of malware infection is a sudden slowdown. If your PC has become slow all of a sudden, you should run a full anti-malware scan.

It would be best if you noticed the speed of the App opening time. However, there might be other reasons behind the sudden slowdown of a computer, like outdated drivers, running heavy programs, low storage, etc.

2. Pop-Ups

There are types of malware that are designed to display ads on your screen. They are called adware, and they bombard their victims with advertisements.

So, if you are suddenly noticing popups everywhere, it’s a clear sign of adware. So, it’s best to use an adware cleaner like Adwcleaner to find and remove hidden adware from your system.

3. Crashes

Since malware sometimes modifies the Windows Registry file, it’s obvious to encounter Blue Screen of Death or BSOD. BSOD usually comes with an error message. You can research the error code on the internet to know the actual cause.

However, if you have started encountering BSOD recently, it’s best to run a complete antivirus or antimalware scan.

4. Suspicious Hard Drive Activity

Another noticeable indication of a potential malware infection on your device is the challenging drive activity. If the Hard Disk activity shoots up to 70% or 100% all the time, it’s a clear sign of malware infection.

So, open the Task Manager on your system and check the RAM and Hard Disk Usage. If both shoot up to 80% level, run a full anti-malware scan on your system.

5. High Network Activity

There are cases where the user is not using the web browser, and the task manager is still showing the network activity. For example, if your PC installs the updates, it will show you in the task manager. You don’t need to worry about anything in that case.

However, if the task manager shows network activity on a suspicious process, you should immediately terminate the process and clean the malware. You need to check the following things.

  • Is there any Windows update at that moment?
  • Is there any program or application that’s downloading or uploading any data?
  • Next, is there any update for a specific app running at that moment?
  • Is there a large download you started and forgot about, which may still be running in the background?

If the answer to all these questions is No, then maybe you should check where all that traffic is going.

  • To monitor your network, you can use one of the following programs: GlassWire, Little Snitch, or Wireshark.
  • To check for a malware infection, use a good antivirus product to check your system.
  • If you suspect that dangerous financial malware has infected your computer, you need a specialized security suite designed to address these types of threats.

Run a full scan with your security program as quickly as possible. These are clear signs of malware/adware infection.
