Nowadays, there are almost 4 billion devices connected to the internet, over 3 billion people that are using it, and more than 7 million active websites and apps. When you take these huge numbers into account, it’s no wonder that the number of hackers, scammers, and fraudsters has increased dramatically as well.

When you use the internet, you’re exposed to hundreds, if not thousands, of malware (malicious software) threats on a daily basis, whether you’re surfing the web, streaming TV shows online, downloading apps, and even just using your email.

Slower Than a Snail

Malware tends to slow down your overall operating system performance, your internet speed, and applications’ speed, which may cause your computer to start and load applications slower than usual. Sometimes, the problem might be a lack of space on your hard drive or a lack of memory (RAM), so it’s important to check these first and to look for other warning signs, which are described below.


Where All These Pop Ups Came From?

While less common than it used to be, unexpected pop-up windows which appear on the system are still a typical sign that your device has been infected with a spyware. It’s extremely important not to click on any of these sudden pop-ups.


Blue Screen of Death

If your computer crashes constantly and a Blue Screen of Death appears, it indicates there is a serious problem with your system. Usually, it could be one of the following: an incompatibility between your software and hardware, or a certain malware issue. The first thing to do is to consult with a technician to rule out a software/hardware issue.


That’s Not What I Was Searching For!

A typical sign that your device has been infected with a certain malware, is when you try to enter your browser’s home page or any other site, and you get constantly redirected to an unfamiliar website you’ve never visited before.


I Don’t Remember Writing That

If people complained you sent them random strange messages or posted something weird on social media, such as “OMG! Look at this amazing pic!”, and you don’t remember doing that, it usually means your computer or mobile device has been infected by malware.


These Icons Appeared Out of Nowhere

If you suddenly notice there are unfamiliar icons of programs on your desktop you don’t remember installing, it most likely means that you’ve accidently installed some type of malicious program. In any case, don’t try to open these programs.


I Think There’s a Ghost on My Computer

Programs that open and close by themselves, operating system that shuts down suddenly, and strange windows that pop up on the booting process could be signs that malware has compromised your computer, and no, it’s not a ghost.


I’m Running Out of Space Here

If your hard drive space has suddenly run out and you haven’t installed any heavy programs, it may indicate you have been infected with a malicious program, which uses various techniques to fill up empty hard drive space and crash it.


Prevention & Cure

Practice the following healthy habits to reduce the risk of being infected by malware or viruses:

  • If you’ve already noticed some of the warning signs mentioned above, the first thing you should do is to Install a well-known and elite Antivirus software and run a full deep scan for viruses. We’ve compiled a great comparison list of the best Antivirus software of 2018 and their features (link to our comparison page). It’s strongly recommended to install an Antivirus even if you haven’t noticed any of the warning signs yet.

  • Make sure your operating system, browsers, and software are always up to date. Often, there are important security updates that fix data breaches.

  • Be cautious when browsing the web, opening email attachments, and downloading free programs.

  • Stay away from suspicious and fishy websites, ads, and apps.
