A malware infection will obviously do more damage to your system the longer it sits unchecked. There is a directive built into most forms of malware to spread to as many systems as possible. Without quick detection and removal, one computer has the potential to infect 10 others on the same network in minimal time.

Therefore, it is crucial to detect and remove any infected devices from your network as soon as possible, so that you can have them scanned and cleaned by a professional like IT Leaders. Our team can also perform a comprehensive IT Cybersecurity Audit to assess your network and individual computers. You can also greatly reduce your risk of a malware infection by keeping an eye out for the following key warning signs. Keep reading on to discover what to look out for!

Desktop Popups - Signs of a malware infection

1. Suspicious Desktop Popups

Hackers commonly attempt to mimic things that users may have seen from a legitimate program, so they’ll be more inclined to click on it without a second glance. Some forms of malware can take on the disguise of being a warranty notice or an antivirus program that pops up on your screen.

If you begin to see a strange subscription alert like ‘Renew Your Antivirus Software’ or have a random warranty renewal appear, these could be signs that your PC has been infected with adware or another type of malware.

2. Sudden System Lag

Computers can become sluggish for a number of reasons, including having too many browser tabs open at once or running a memory-intensive program. Typically though, you will soon realise when your computer and programs begin to noticeably slow it down.

A newly sluggish system or unusual system lags could indicate a data breach or malware. An example of this could be if you don’t have any programs open except Notepad or another simple app, and yet you experience freezing. When malware is running in the background, it can often eat up system resources and cause your system to get sluggish out of the blue.

3. Crashing Applications

Applications should not just crash randomly. There’s generally always a reason behind this. Either there has been an issue with an update, you have faulty software running, you have run out of space, or something else may be conflicting with that application’s files.

If you suddenly experience apps crashing, requiring you to restart the app or reboot your system altogether, then this is another telltale sign that a trojan, malicious code or a virus may have been introduced on your computer or network.

4. Redirecting Home Page Browser

A common malware technique is to redirect a user’s home page so have your PC scanned right away if you open your browser and land on a new homepage. The malware will change the default home page of your browser and potentially infect your system in a matter of seconds. Your browser may redirect you to a pop-up ad site or some other type of phishing site. Unfortunately, changing your homepage back in your settings will not fix the issue and the malware needs to be removed as soon as possible by an IT professional like IT Leaders.

5. Unusual Rebooting

Certain kinds of malicious code can also make your system reboot without warning. Getting anything done can be extremely difficult, clog up your workflow, and cause you to lose the work you have just completed. This may happen when malware is changing core system files behind the scenes. When your files become corrupted, your system can start rebooting unexpectedly & becomes unstable.

6. Missing Hard Drive Space

If you discover that a large amount of your hard drive space has now suddenly disappeared, it could be a sign that a malware infection is taking up your space. It’s possible for some types of malware to even make copies of your files or to introduce new files into your system.

When searching for files, don’t expect to find the term “malware” though. It’s common for dangerous activities and malware to disguise themselves as harmless system files with generic-sounding names. This essentially means that they remain undetected in your system for an extended period of time, inflicting extensive damage.

7. Discovery of Corrupted Files

Corrupted files could indicate that you have been infected with ransomware or another form of malware. Occasionally, files become corrupt for other reasons, but this is a serious issue that warrants a comprehensive malware scan.

8. Random PC processing sounds

The “thinking sounds” our computers make when they are processing memory-intensive tasks are familiar to many of us. The whirring sound usually goes away once the activity is completed, however.

This continuous processing sound could be an indication that malware is running in the background on your computer, so you should check it out if you hear it even when you are not doing anything particularly intensive on it.
