List of Warning Signs that Your Computer is Malware-Infected
Here is one of the scenarios that you may not like, but which could unfortunately happen to you every day. You work on an important project and suddenly you begin to see annoying pop-ups appearing on your computer. Moreover, loading your files or apps takes too long. You wait until you start wondering: “Is my computer malware infected? “Unfortunately, the response could be” yes “and your PC could already be compromised by viruses or next-genre malware that slow down performance.
This is one of many warning signs showing that your PC may be infected with malware. But there is much more to be understood and understood so that you can act quickly.
In this article, we will show you the most common warning signs of malware infection on Microsoft Windows-based machines and what you can do about it.
Scenario #1: “My computer applications are running slowly and take longer than usually.” This scenario might mean that you have viruses on your computer.
I know, seeing it work slowly is so frustrating.
It is well known that one of the main activity of the malware is to slow down your operating system, regardless of whether you browse the internet or simply access local applications.
- What can you do?
First, you must examine the causes and try to understand what is happening.
Here are some of the most common problems slowing your PC down: 1. The RAM memory of your system is low.
- This may be due to the large number of applications that you currently use.
- Windows Task Manager will assist you in seeing which programs use your RAM most.
- Press simultaneously CTRL+ALT+DELETE, select Task Manager and a list of the current apps that are open will be displayed.
- On your hard disk there is no storage space.
In this case, all your stored files need to be checked and cleaned up.
- You may have too many computer resources in your browser.
In the Windows Task Manager, you can see how your browser works.
What can you do about the speed of your browser?
Remove unnecessary add-ons to the browser. Here is a list of Chrome extensions to help increase your security online–simply make sure that you choose what you really need and don’t simultaneously use all of our ideas. Or if your favorite extensions don’t like saying goodbye, just disable them so that they don’t run on every webpage.
Delete cache excess
If you have tons of cache and browsing history, this may be why your browser is so slow.
When you open new ones, close unnecessary tabs. Oh, we were all there, the tabs clutter. I know, you may think that you really need to go back to every tab you opened in a browsing session. But be honest, most likely you won’t have to do it. Just remember, you can always reopen your latest browsing history / recently closed tabs–well, unless in Incognito / Private mode you are browsing, but that is another story.
Your system may be partitioned
Files kept on a hard drive are fragmented over time. Simply put, this means that parts of these files are stored in various drive areas and not next to each other. The storage space is therefore inefficiently used and reduces the performance of your PC and makes it harder to open a file for your operating system.
This can be fixed with the defragmenter for the Windows disk (Optimize Drives).
The defragmenter tool is running automatically in Windows 10, Windows 8 and Windows 7, so you probably do not have to worry about this.
You have not updated your Windows OS or used outdated drivers.
Always ensure that your operating system is constantly updated. Uncontrolled systems may have faults that malicious actors can exploit so make sure you always run the latest Windows version.
You can start to take a look at a potential malware infection if you have already thoroughly verified these possible causes and everything seems to work well.
Scenario #2: “I continue to get annoyed ads that randomly or strange messages are opening on my computer screen.” Unforeseen pop ups on your screen are a typical sign of a malware infection that will hit your computer.
This form of malware is known as spyware and aims to collect and steal sensitive information from users without their knowledge.
The main issue is not only the numerous pop-up windows affecting your internet browsing in this specific case. It’s also very hard to remove them from your system.
These pop-ups are not only frustrating; they are usually bundled with other covert malware threats and can be much more destructive to your operating system.
They can be disguised as legitimate programs and track your web browsing information or monitor your online activities for passwords and other personal information.
NEVER CLICK is strongly recommended in a suspicious pop-up!
To prevent malicious threats on your computer, ensure that you use these security measures: do not click on pop-up windows.
Do not reply to unwanted emails that look odd. Always check the email address of the sender and never open accessories or click weird links.
Be very careful when trying to download free apps.
Use a next-gene threat prevention solution to identify and block online hazards prior to infecting your computer.
Scenario #3: “My laptop continues to crash when I watch videos or games in Youtube. It just freezes and then a blue screen appears. “So you get the popular BSOD (Blue Death Screen). Then he recovered and “told” you Windows recovered from an unforeseen shutdown.
There may be two things that cause this sort of problem: you may have a technical problem caused by a possible incompatibility between your software and/or hardware.
It could be a malware problem.
If you suspect a technical problem, it might be caused by these problems: Does your PC have different programs in conflict?
Are there orphaned registry keys that could eventually crash your system that were not deleted?
Orphaned registry keys are pieces of data that were left behind during your computer uninstallation process. Not only do they take inappropriate space on your PC, but they can cause a serious problem with its proper functionality.
How to fix this: Use the Registry Editor (Regedit.exe) which you can open in the Windows search bar. You select the run command from there.
For malware infections: run a full scan of a good antivirus product on the system. And make sure you never get malware infected by using a full and all-in – one security suite that catches threats before they occur.
Scenario #4: “I began to receive this pop-up message < Windows disk space is running out (C:). >” When you receive this warning message, it means that there is no free space left on a particular partition on your hard drive (in this case, C). This issue is reported by more and more users.
The reason? Here’s what Microsoft has to say: This can happen if the free disk space is below the notification threshold for the Disk Cleanup utility in your computer.
How can I fix it?
First, you have to check whether your physical storage space has increased lately or whether some of your files are lost or changed their names.
Secondly, make sure you remove all old or unnecessary files that can lower the performance of your PC.
Third, this could be another sign of infection with malware. There are so many kinds of malicious programs that use different methods to fill in and crash the space available on the hard drive. Make sure that you use an anti-malware solution that scans and does not allow any viruses or threats to reach your system automatically.
Scenario #5: “Every time I start my PC, I notice a suspicious increase in internet traffic for quite some time.” There is a chance that an unusually high network activity is occurring on your PC that could cause malware infection.
What can I do?
Check each of these items: Last update for your computer from Windows Is there a program or application that downloads any information?
Is there an update for a certain application currently running?
Is there a big download you started and forgot, which can still run in the background?
If all these questions are answered by NO and you can not find a cause for your increased Internet traffic, this may be a sign of malware infection. In this case, a specialized security suite should be used to address advanced and new threats online.
Scenario #6: “My homepage has changed and I do not remember it myself.” If you have seen this unusual behavior or if you have seen a new toolbar out from the outside or if you have been redirected to a different web address from the initial one, these may be evidence of malware infection.
It usually happens when you visit a website, and click on a link or pop-up window accidentally.
This triggers you to download and install the unwanted software on your device. Not only are the effects irritating, but they are also malicious and may compromise your data.
What to do?
You can always change your homepage address manually from the settings of your browser.
However, unfortunately, the true cause of this behavior can be much deeper rooted and be a sign of a more serious malware infection.
The best way to avoid compromising your files, passwords and payment details is with a comprehensive, next-generation security prevention and mitigation solution.

Scenario #7: “My PC is weird as I get unusual, unexpected messages,” that’s usually the type of warning message that causes you to wonder, “What’s going on with my computer?”There are a few frequent warning signs to look at: you see programs automatically opening and closing.
- Your Windows OS closes unexpectedly, for no reason.
- You noticed odd windows when your PC is trying to boot.
- Windows tells you that some of your drives have lost access.
- While the root cause may be a technical problem, it can also be a warning sign that malware takes over your computer and slows down its activity.
How can the impact of malware infection be mitigated?
Keep your Windows system up to date. Follow these steps.
- Use a malware solution that does not allow threats to enter your computer.
- Please consider reinstalling your OS. This 13-step guide will show you how to secure your PC after re-installing your system.
- Were you aware that some malware types are sneaky and can deactivate the security solution?
- Well, yes, they are designed to make it difficult to detect users without defense.
- You could take into account the malware infection scenario if you already tried to boot again, closed and opened the security solution and all your troubleshooting efforts seemed useless.
- It is especially known because conventional antivirus solutions can’t easily detect, block or remove next-gen malware and advanced malware (e.g. ransom ware, adware or financial malware).
- You can therefore be exposed to all kinds of attacks, and we strongly suggest you improve protection by adding multiple protective layers.
- Read these 10 reasons why antivirus detection is avoided by second-generation malware.
Scenario #8: ‘ I’m running an antivirus product and keep receiving the message < Disable protection>.’ If your antivirus solution doesn’t seem to work anymore or you disabled the update module, you should check out immediately how to fix it.
Scenario #9: “My friends tell me they’re getting strange random messages I haven’t been sending from me on Facebook.” If your friends have recently had several strange messages or suspicious links, and you haven’t sent them, you’d probably have been malware infected.
Here is a good example of Facebook Messenger malware spreading and tricking users to click on links from one of their friends.
First, check your online accounts and see if the random messages from one of your accounts have been sent. If something like this happens, follow these safety measures immediately: log out of all your accounts. We log into multiple devices for most of our online accounts and often forget to log out. Make sure you log out on all connected devices from your online accounts.
For all your online accounts, use unique and strong passwords. Remember to always change passwords! Never use the same password(s) for several accounts, because when you hack, you will expose them all and stolen your valuable information. This password security guide will assist you as an expert with master passwords.
Start using RIGHT NOW two factor authentications. Want to increase your security control? Then add this second safety layer that requires an additional authentication step along with your credentials during the login process.
Scenario #10: “There are those new, unknown icons that I do not recognize on my desktop.” If you’ve noticed unknown icons and new ones on your PC, you’ve most likely accidentally downloaded these sneaky programs, named PUPs. These are malicious programs that can damage you and expose you to data leakage, display annoying on-screen ads or pop-ups or add a toolbar on your browser.
You often come along with suspicious software, which you have finally installed. You may accidentally have given your consent to install other tools you did not notice were present.
But while good internet practices can protect you from PUPs, proactive security software is recommended.
Scenario #11: “I sometimes see unusual error messages shown on my computer.” An error message such as this could suggest that your system has a bug that must be fixed. Or it might be a warning sign of infection with malware.
These types of error messages with missing or corrupted file folders show that the performance of your PC has been compromised.

Use a next-gen malware solution that will protect you from unwanted threats.
Scenario #12: “It seems that by clicking on the button I am unable to access my control panel.” If you are dealing with this question and your control panel is not opened, it means your computer has a technical problem and it doesn’t function properly.
How can this be fixed?
The first thing to do is run a complete PC scan.
See if you can open the Safe Mode Control Panel and follow the steps described here. It may also show that your computer is vulnerable and exposed to cyber-attacks. Use a proactive security solution after completing a scan with your antivirus product to keep your confidential information safe.
Scenario #13: “All looks like my PC works perfectly. Are there any chances of being paranoid and still looking for malware? “It is essential to be a little paranoid and careful when it comes to data protection, although everything appears normal. Why? Why? Because cybercriminals are creative in the most unexpected places and can hide malware, leave no visible marks and still infect your PC.
Everything on your PC may seem perfectly normal until a boot on your system can still wait for instructions to access and collect your most valuable information.
The best way to ensure that your system does not get malware by installing a security solution which scans your machine and stops threats before touching your PC.
Scenario #14: “My laptop works very slowly and sometimes the < Flash does not function > browser error.” We received the aforementioned message from one of our readers.
- If you get the message on your PC, disabling Flash and trying another alternative could be a good idea. Flash has many vulnerabilities we discussed before.
- Notwithstanding the browser you are using, Firefox could be a warning sign of malware infection on your computer.
- Here are some useful tips: Keep your Windows system updated and consider reinstalling your OS if this problem persists.
- Do a complete scan of all files and applications installed on your PC with an AV solution to see if any malware is being detected.
- Consider installing a proactive security solution to improve computer protection and to avoid malware and other online threats.
- Make sure you restart your PC if you haven’t accomplished this task in a while.
- Look at the Task Manager function and see which programs run in the background to reduce your PC performance. It gives you an overview of what apps and programs and how much space.
- Make sure you’ve installed the latest version of Adobe Flash, but if you don’t, download it from here and follow the instructions. Note that after this procedure, you should restart the computer.
If you don’t want Flash Player on your computer, you can follow and uninstall these easy steps.
Scenario #15: “I used a USB external drive and it was infected with a virus when I connected to my computer and all files suddenly became shortcuts.” Here’s another warning sign that showed the malware could be infected on your computer. If you used an external USB drive or an external flash drive to copy information without previously scanning, it may explain the appearance of these files.
If all of your images, files and other documents appear as shortcut files, they may be infected with malware. They are not accessible. These malicious files can compromise all your computer data, rename your files and create chaos and trouble.
How can this be fixed?
Here are some useful tips and security measures when your files have been compromised: Scan your USB disk fully and check for possible viruses and malware. Should not be detected by the antivirus solution on your external drive, you should format it and clean the area.
Use the Prompt command (cmd) on your Windows computer while the USB drive is connected to your device. To access it, enter the Start menu, enter “Cmd,” and under a list of programs you’ll see “cmd.exe.” Click on it and you’ll be directed to the command line Windows to recover the virus from. It may take a while, but your computer will be cleaned up.
Make sure you add multiple security layers to your protection and consider using a proactive security solution.
Can you avoid infections with malware?
Yes, you can definitely do it if you pay close attention to and prevent these early signs of malware infection.
Make sure your operating system, browsers and plugins are up to date because online criminals can be kept at a loss by patching your software.
