Were you aware that there are over 10,000 computer viruses nowadays, according to University of Houston-Downtown?
A computer virus can cause many problems. It can slow down your system, steal information, or even damage files.
It’s important to understand how to know if your computer has a virus. Here are some common virus symptoms to look for.
Slow Performance
One of the first signs of PC infection is slow performance. Sometimes, viruses use your system’s resources, which slows everything down. Even simple tasks like opening a browser may take much longer than usual.
Frequent Crashes or Errors
Frequent crashes are another major sign. If your computer keeps freezing or suddenly shuts down, it may have a virus. Errors that pop up without explanation are also a red flag.
The system might display strange error messages that you have never seen before. These computer malware signs suggest something is wrong with the system.
Pop-up Ads Everywhere
If you’re getting a lot of pop-up ads, even when you are not online, this is a clear sign of malware. Adware, a type of malware, causes these unwanted ads. These pop-ups can also trick you into clicking links that will install more malware on your device.
Unfamiliar Programs on Your System
A sign of malware is seeing software or programs that you didn’t install. Some viruses install additional programs without your permission. You may notice new icons on your desktop or in your program list.
Your Browser Is Acting Strangely
Malware often affects your internet browser. If your homepage changes without your permission or you are redirected to strange websites, it could mean a virus is present. This is known as a browser hijack.
Malware can also add unwanted toolbars or extensions to your browser. These computer virus symptoms make it hard to browse the web normally.
Antivirus Software Is Disabled
Viruses often try to disable your antivirus software. If you notice that your antivirus is turned off, and you didn’t do it, this is a serious sign. Some malware programs are designed to disable security features so they can spread easily across your system.
Your Friends Receive Strange Messages from You
Some viruses can access your email or social media accounts. If your friends or contacts start receiving strange emails, messages, or links from you, your computer might be infected. These viruses spread by sending themselves to your contacts, hoping someone will click on the infected link.
How to Scan for Malware
If you notice any of these virus symptoms, you should act quickly. Detecting computer viruses is key to protecting your system. Most antivirus programs can scan your system for viruses.
Open your antivirus software and run a full system scan. You can also take your computer in for professional help.
