These include your files, personal information, and cyber currencies. This is why most antivirus software multiple scanning features. These systems keep the antivirus software updated about emerging malware.

Computer malware is unwanted programs that can enter a computer system to do harm.

Aside from that, it can adapt and evolve at a much faster pace than even antivirus software companies can keep up with.


Malware is fast evolving into a criminal and hostile nature. Web-based malware are often used as a point of attack by cyber-criminals to get into Windows PCs. In particular, they set up “traps” online through fake websites and sign up sheets, and upload malware-infected files and entice you to download them. These malicious files and running scripts can infiltrate your system. Once there, they can lock-up important files, copy your sign-in information, or steal your cryptocurrencies. There’s even new malware that can manipulate antivirus software into turning itself into malware!


What are the signs of an infected computer?

Most malware are designed to remain undetected which makes it hard to figure out whether a malware infection is behind it. However, there are so-called behavioral patterns that can indicate an infected system. If you notice slow computer performance or loss of and/or intermittent internet connection, these are symptoms. Other signs of an infection include unwanted pages that pop-up on your web browser and sudden changes in your computer’s language. Consequently, the most glaring sign is when you receive notifications from your antivirus saying your computer is infected. 


Keep in mind that there are other possibilities that could explain your computer’s erratic behavior. In order to figure out why your computer is starting to act like a possessed creature or why your internet is so slow, consider other potential causes such as a  full or corrupted hard drive, too many programs running in the background, or any hardware conflicts. As more symptoms show up pointing to infection, the more likely for it to be exactly that.


Why do I need to have antivirus software?


If you use the internet for any purpose, you are already at risk. By means of simple access to the internet, you are exposed to multiple threats on many fronts. And there are countless ways to get infected.  You can access infected files through email. You can come across websites that secretly record your sensitive personal information.
