How to know that the computer is infected with a virus?

How to know that the computer is infected with a virus
Share on FacebookShare on Twitter

A virus can infect a computer in a number of ways, the most common of which involves downloading infected files – either knowingly or accidentally. Pirated audio or videos, photographs, free games, toolbars, and phishing/spam mails with attachment files are all popular offenders. Viruses can also be received by going to malicious sites or following the links or advertisements that lead to an unfamiliar and insecure website. Even connecting to a maliciously infected external drive like a USB can infect your computer.

What Are the Indications of Viruses?

The computer may be infected with the virus if you see any of the following symptoms:

  • Computer performance is slow, and it takes a long time to start or open programs.
  • Shutting off or restarting issues
  • Files are missing
  • System failures and/or error messages on a regular basis
  • Pop-up windows that appear out of nowhere
  • Applications that display without you having to download them
  • Overworked hard drive (When you aren’t doing much, the fan produces noises and appears to be buzzing and working hard).
  • Emails that are sent independently from your accounts
  • Redirects or latency in the browser
  • Anti-virus software or firewalls that aren’t working properly

How to Determine Whether or Not a Process is a virus?

You could be concerned if your computer is infected because you noticed an unusual process in the Windows Task Manager that you can access by typing Ctrl+Shift+Esc or right-clicking the Windows taskbar and tapping on “Task Manager.”

Malware that behaves badly will typically consume a lot of CPU, memory, or disc space, making it stand out. If you’re unsure whether the software is dangerous, right-click it in Task Manager and choose “Search Online” to learn more.

If you search the process for information regarding malware, it’s a good bet you have malware. However, just because a process appears genuine does not mean it is virus-free. For Example, a process could pretend to be “Google Chrome” or “chrome.exe.” If you believe your computer has been attacked with a virus, it is recommended to run an anti-virus scan.

What to do if the PC is infected with a virus?

  • Start by running a thorough system scan with the anti-virus software and an anti-malware tool if you suspect your machine has been affected. Examine the threats and take any necessary action (the anti-virus software will guide you through the process). If you are not able to remove the virus or infected files with the help of the anti-virus software, consider restoring the computer to a previous backup before the troubles begin.
  • Try removing all of your computer’s temporary files. The method for deleting those files varies in every system, but these procedures are simple enough for any user to learn and implement. If your system is acting weird and can’t get to the files you want to erase, try starting it in safe mode. Safe mode disables specific programs so you can concentrate on fixing the problem.
  • You can reinstall the operating system on your computer. If you don’t know how to do it, take your laptop to a local computer store and have an expert look at it.
