Whether it’s downloaded by accident or insidiously planted on a device, malware can cause a host of issues for an enterprise, from slow systems to stolen data files. While sometimes it’s clear your computer has been infected, other forms of malware are specially designed to remain hidden, even from your device’s operating system. In the following sections, we’ll explain some of the tell-tale indicators you can keep an eye out for to ensure your company computer hasn’t been hit by this malicious form of software.

What are the obvious signs of a malware infection?

Ransomware notes

Some forms of malware want to be noticed, like ransomware that encrypts sensitive company files and demands a payment for their release. You’ll know you’ve been infected when a ransom note pops up on your screen with a requested sum for the safe return of your data.

Barrage of pop-ups

A pop-up appears, and when you close it, another opens. A constant series of pop-ups can indicate malware on your machine, especially if you’re not even connected to the internet.

New homepage

If your choice of homepage has been altered, there’s a good chance your device has a malware infection. Additional signs may include some new toolbars beneath your browser you’re unable to remove.

Browser redirects

If you find that whatever link or address you try to go to redirects you to a different website than the one you intended to visit, it’s likely you have malware onboard.

What are more subtle indicators of an infection?

Slow running devices

From a lack of RAM or hard drive space to running too many apps or programs simultaneously, there are many reasons for a slow computer. However, when none of these are the case, malware may be slowing your machine.


While malware isn’t the only reason your system or its apps might crash, types of malware like rootkits can be the cause, creating instability in your machine’s innerworkings.

Unfamiliar desktop icons

If you identify icons for apps you never installed on your device, this may well be a malware issue. Some malicious software is hidden in bundles you buy and becomes installed with other software when you action a tick box after not reading the terms and conditions properly.

Web browser freezes

Finally, if your web browser is unresponsive, malware could well be the reason. A slow internet connection could be at the route of your troubles, but if you check out your Wi-Fi signal and consult your provider on download speeds and they pass the test, malware could be the culprit.
