Are you wondering if your computer has a virus? Or do you just want to stay vigilant and know the signs? Either way, computer viruses and malware can be a nightmare. Let’s explore the common signs of computer infections and some ways to prevent them from disrupting your computer.
Sluggish performance
If your computer is suddenly operating in slow motion, it may be infected by a virus. Computer viruses typically utilize a computer’s processing power for malicious activities. If you notice big changes in your computer’s performance, run a virus scan.
Pop-up ads
If your computer starts displaying pop-up ads while you’re browsing the internet or using other programs, it’s a sign that it may have a virus. Pop-up ads can lead to malware installation or other malicious activities. If you’re seeing pop-up ads, avoid clicking on them and run a virus scan as soon as possible.
Strange, new programs
If you notice new programs on your computer that you don’t remember installing, it’s possible that your computer has a virus. These programs may be malware that is designed to perform malicious activities. Uninstall these programs immediately and run a virus scan.
Sudden crashes and freezes
Viruses can overload a computer’s resources or modify critical system files, which can lead to frequent crashes and freezes. If your computer is crashing or freezing frequently, it may indicate that it has a virus. Run a virus scan as soon as possible.
Strange network activity
Sometimes, viruses use your computer’s Wi-Fi/internet network to perform malicious activities. If you notice unusual network activity, such as your internet connection or processing speed slowing down, it’s probably a good idea to run a virus scan and check for any unusual programs or processes running in the background.
Changes to browser settings
Viruses have been known to sometimes modify your browser settings in order to redirect you to malicious websites or display more ads. If your web browser’s homepage or search engine has changed without your knowledge or consent, it may indicate the presence of a virus. Reset your browser settings and run a virus scan.
Missing files
A virus can delete or modify your files to perform malicious activities. If you notice that some of your files are missing or have been modified without your knowledge, it’s possible that your computer has a virus.
How can I protect my computer from a virus?
- Utilize built-in security and anti-virus features. It comes standard on all computers these days, so no need to download an external software! These are often scams.
- Avoid downloading files from unfamiliar or untrusted sources.
- Don’t click on suspicious links or pop-up ads. Consider changing your browser’s settings to block pop-ups entirely.
- Keep your operating system up to date.
- Use strong and unique passwords across all of your online accounts. You can store these in a virtual password safe for easy access.
