Common Signs of a Virus-Infected Computer
Before we dive into the signs of a virus-infected computer, it’s essential to understand what a virus is. A virus is a type of malware that replicates itself by attaching to other programs or files on your computer. It can come from various sources, including the internet, email attachments, and external devices. Here are some common signs that your computer may be infected with a virus:
• Slow Performance: If your computer is taking longer to start up, launch programs, or respond to commands, it could be a sign of a virus. Run a virus scan to check for any potential infections.
• Pop-ups and Ads: If you’re seeing more pop-ups, ads, or unwanted notifications on your screen, it may be a sign that your computer is infected with malware.
• Unusual System Errors: If your computer is experiencing unexpected system crashes, errors, or freezes, it could be a sign of a virus or malware infection.
• New Programs or Files: If you’ve recently installed new programs or added files to your computer, but they’re not doing anything, it could be a sign that they’re infected with a virus.
• Changes to Your Home Page: If your default home page has changed to a strange website or you’re seeing a different search engine, it may be a sign of a virus infection.
