6 Symptoms Of An Infected Computer

6 Symptoms Of An Infected Computer

Without installing a top antivirus software, your computer is at risk for viruses, malware, hacking, and all kinds of suspicious activity. So if your device isn’t protected, how can you know if you’ve got a computer virus?


Here are the 6 most common symptoms of an infected computer:


1. Slow speed

Both the internet and your computer itself will significantly slow down if you’ve got a virus. This can happen because the attacker has uploaded a large application or multiple malicious files to your computer, bogging it down with excess data. It can also be that the purpose of the virus is to slow down your system enough that the hacker can obtain your private information.


2. The Blue Screen of Death

Especially on older systems, the Blue Screen of Death would appear when crashing to inform you that there is a technical error. This error is typically caused by malware altering or overloading the computer and preventing it from starting up properly. These days, the actual blue screen is less common, but if your computer or any specific applications are regularly crashing, you are most likely dealing with an infection.


3. Low disk space

If you’ve never had a storage space issue in the past and aren’t excessively downloading or creating files, you shouldn’t have any problems with this. So when you get a message telling you your disk space is low, be suspicious. This is possibly due to the unwarranted loading of files or applications onto your system by hackers and viruses. Some people incorrectly attribute this to an antivirus software. However, that will not be the culprit here, especially if you use a cloud-based system like Panda Global Protection.


4. Excessive toolbars

When you install something from an unknown source, it can result in the addition of toolbars and extra search bars to your default browser. These are usually just a front for the real, malware-carrying application that is being transferred to your computer.


5. Strange messages or pop-ups

Pop-ups are a normal part of surfing the web. Most websites will have pop-up advertisements on them, but this doesn’t mean you should click on them without caution. And if you’re getting pop-ups and unsolicited messages on the device itself without the browser being open, it’s likely due to a virus.


6. Disappearing files

If you ever think to yourself, “Hey, where did my files go?” this is a huge red flag for a computer infection. Your files will never just hide themselves on their own. The most probable explanation is that your computer has been the target of an attack. Hopefully, you will have a backup plan to retrieve your lost files, but if not you should be looking up data recovery software reviews to find something that will assist you if this sort of thing ever happens with your device.


The best way to prevent ever having to diagnose your computer with a virus is to be proactive. Install an antivirus or security software to your computer, tablet, and cell phone to ensure you never have to deal with this problem again.
