10 Warning Signs of a Malware & Virus Infected Computer

#1 Frequent Crashes and BSOD Errors

Frequent Crash and BSOD Error

If your system and programs crash constantly or the notorious BSOD screen appears regularly, it is a clear warning that your framework is not working properly and you should look into it.

System crashes and BSOD errors mainly occur due to two reasons:

  • You could be dealing with a technical glitch caused by a potential incompatibility between your software and hardware equipment.
  • Or it might be a malware issue that is causing your system to crash or not boot into the operating system.

If it is due to malware infection, you need to run a complete scan on the system with a good anti-virus product. However, while doing this, just make sure you have chosen a reliable security solution that includes a firewall, automatic updates, and real-time scanning options.

#2 Slowdown


How often do you feel exasperated with your system acting up, being slow, or freezing up? If your operating system is taking longer than usual to boot up then you have some kind of issue related to malware.

It is known fact that malware has the tendency to slow down an application or the entire machine; all of a sudden, Windows is not as responsive, actions are taking longer than they should, and so on.

If you observe something like this and you’re not using any resource-heavy program or application, check for other causes first.

It may be a lack of RAM, a fragmented system, a lack of space on your hard drive or perhaps an out-dated or damaged hardware influencing your drive.

If you have already thoroughly verified these possible situations and all seems fine, you can start considering a potential malware infection.

#3 Pop-ups & Annoying Notifications

Pop-up Ads and Notifications

The windows jumping on your computer screen with false proposals for software installation, pop-up ads or even porn sites redirects are some of the typical signs of a malware infection.

This form of malware is known as spyware which is developed with the core intention to accumulate and steal users’ sensitive data.

Pop-up ads are not only annoying, but they usually come bundled with other concealed malicious program, and which could be far more destructive for our systems.

To avoid spyware infection and its impacts on our devices, keep in mind a few security measures:

  • Never click on any suspicious pop-up window
  • Always treat unsolicited emails or messages with skepticism
  • Be careful when you are trying to download freeware programs.

#4 Default Search Engine, New Tab URL, and Homepage Has Changed

Default Search Engine Has Changed

Have you noticed that your default search engine and the homepage has been changed?

Did a new toolbar extension pop out of nowhere and landed at top of your web browser?

If yes, then it is possible that your computer is infected with malware. This usually happens when you visit a website and accidentally click a malicious URL or a pop-up window.

This triggers the malicious programs to download and install on your system. It modifies internet settings to cause frequent redirects and also keeps a track on your browsing activity.

The information tracking leads to data theft of banking details, social media accounts, passwords, geolocations, and IP address.

We recommend running a complete system scan with your security solution as soon as possible to create a secure and robust firewall against malware threats.

#5 Security Solution/Antivirus is Disabled

Security Solution Disabled

Have you ever think that some malware can disable your security solution? Well, you should know that some types of malware are specially designed to disable antivirus protection first.

This type of malware is often harmful, leaving users without any defense and also making difficult to detect them.

Since traditional antivirus software can’t easily detect, block or remove next-gen and advanced malware threats (such as ransomware, adware or Trojan assaults).

Thus, you can get exposed to all kind of attacks, and we strongly recommend enhancing your protection by adding multiple layers of protection.

#6 Suspicious Shortcut Files Popping Out of Nowhere

Shortcut Files

This one is actually pretty evident. If all your images, files, and other documents (well, ‘most’ if not ‘all’) are showing up as shortcut files and you aren’t able to access any of them, hold your horses’ because they could be infected with malware.

These files can easily compromise your data, even rename them… creating a lot of chaos and confusion in the process.

You can be robbed off your data right under your nose without getting the slightest hint that things are being transferred in the background.

Here’s a tip: Always make sure that you add multiple layers of security using the best anti-malware software. Trust us! This will amplify your protection.

#7 Unusual Error Messages and Windows Warnings

Fake Windows Warning

If you see unusual error messages saying that your Windows operating system is damaged (depending on the system that you’re using) or you have missing & corrupted registry files, then it is a possible warning sign that your computer is infected with malware.

Out-dated/older versions of the Windows operating system are an easy target for potential cyber-attacks.

To avoid such infections, we recommend to run an antivirus program and make sure your operating system is up to date. By doing this you can keep your system free from virus and other Windows alert scams.

#8 Unfamiliar New Icons, Add-ons/Extensions

New Icons And Add-Ons/Extension

Well, if you have recently discovered unknown icons and new search engine (with malicious add-ons/extensions) on your Windows PC, then you might have accidentally downloaded a piece of software that contains PUP’s (Potentially Unwanted Programs).

PUP’s are malicious programs and can do a lot of damage by stealing sensitive personal information and displaying intrusive advertisements, pop-ups and can even replace your existing browser’s homepage.

They are a type of malware which ultimately aims at harming and infecting the machine, therefore, to keep your PC safe and protected we recommend to run a full scan of your system using good antivirus software.

#9 Flood of Internet Traffic

High Internet Traffic

There are cases when the user is not connected on Internet through his web browser, and there is no application that may relate to online servers to download and upload any data, however high suspicious network activity can still be observed.

If your Internet traffic suspiciously increases for no apparent reason, it might be a hacking attempt to disrupt normal traffic of a server, service or network by overwhelming the target resources or its surrounding infrastructure with a flood of fake Internet traffic, and ultimately resulting in a denial of service to legitimate users.              

To minimize the risk of malware infection, it is recommended to use a specialized security suite designed to address these type of threats to protect your system from all kinds of disarray.

#10 Unable to Access the Control Panel, Task Manager or Command Prompt

Control Panel Access Denied

Do you find yourself in a situation where you can’t access the Control Panel, Registry Editor, Task Manager or Command Prompt?

Malware is becoming more adaptable, resilient and destructive than ever before and also developing new tactics to bypass the security checks.

So, malware and viruses first infect your control panel and make it inaccessible which restricts users from uninstalling the malicious files and folders.

Therefore, if you can’t access the control panel we suggest using a proactive security solution to keep your confidential information properly safe.
