Realizing your PC, Mac or laptop might be infected with a virus or malware (malicious software) is worrying, but with careful and decisive action, removing a virus is quicker and easier than you might think.
How do I detect a virus on a Windows PC?
It’s not always obvious when your computer is infected. Some of the warning signs indicating that your PC or laptop might have a virus, Trojan, worm, or some other kind of malware are:
A very slow-running computer
Pop-up messages that appear out of nowhere and are hard to remove
Unrecognized computer programs launching on their own laptop computer
The sound of the hard drive in constant action
Anyone of these symptoms might be caused by a virus or a different kind of malware. If you’re experiencing two or three of them at the same time, that’s a strong indication that you’ve got a virus. That said, a lot of modern malware, like spyware and cryptominers, go out of their way to stay as hidden as possible.
To catch those, you’ll need to download an antivirus program now. You can download AVG AntiVirus FREE and have it running in just a few minutes. Antivirus programs come packed with scanners and other tools for finding viruses and malware, even if your computer isn’t exhibiting any of the symptoms.
Did Your Antivirus Say a Virus Was Detected?
If you saw a message pop up that says a virus was detected, that’s a good thing. Your antivirus noticed a virus and likely removed it without prompting you.
This sort of message doesn’t mean that you ever had a virus running on your computer. You could have downloaded a file that contained a virus and your antivirus removed the file before it could ever cause a problem. Or, a malicious file on an infected web page could have been noticed and dealt with before it caused any problems.
In other words, a “virus detected” message that occurs during normal use of your computer doesn’t mean the virus actually did anything. If you see a message like this, you’re likely visiting an infected web page or downloading a harmful file. Try to avoid doing that in the future, but don’t worry too much.
