Patti Croft, AuthorCatherine McNally, Editor| Last updated Jul 8, 2022
Is your computer acting strange lately? Maybe youve noticed it isnt as responsive as it was when you first got it. Youve tried rebooting, thinking that may solve the problem, but it hasnt helped.
Its possible you could have a computer virus. If you do have a computer virus, theres no need to beat yourself up about it. Most of us have been in this same situation.
With so many viruses created each year, its hard to navigate the internet without at least one of them trying to infect your device. Every week, Google finds 50 websites that have malware. Fortunately, there are signs and symptoms you can check and watch for to help you decide if thats the issue.
Spam Sent From Your Email Address Or Social Media
Malware can work in many different ways. One variant sends random messages to your contacts list. This infection spreads across the internet by tricking people into clicking on an infected link. The link then spreads the malware to that person, who unwittingly spreads it throughout their friend list. By logging out of your accounts, creating strong passwords and implementing security measures like two-factor authentication, you can thwart any further intrusion.

What Is Rogue Security Software
A rogue security software program tries to make you think that your computer is infected by a virus and usually prompts you to download or buy a product that removes the virus. The names of these products frequently contain words like Antivirus, Shield, Security, Protection, or Fixer. This makes them sound legitimate. They frequently run right after you download them, or the next time that your computer starts. Rogue security software can prevent applications, such as Internet Explorer, from opening. Rogue security software might also display legitimate and important Windows files as infections. Typical error messages or pop-up messages might contain the following phrases:
Warning!Your computer is infected!This computer is infected by spyware and adware.
Note If you receive a message in a popup dialog box that resembles this warning, press ALT + F4 on your keyboard to close the dialog box. Do not click anything inside the dialog box. If a warning, such as the one here, keeps appearing when you try to close the dialog box, its a good indication that the message is malicious.
Are you sure you want to navigate from this page?Your computer is infected! They can cause data lost and file corruption and need to be treated as soon as possible. Press CANCEL to prevent it. Return to System Security and download it to secure your PC.Press OK to Continue or Cancel to stay on the current page.

What To Look For In Mac And Windows Computers

- Excessive freezing and crashing
- Emergence of unknown ads, popups, or files
- Browser changing the home page, unknown toolbars
- Unknown sent messages or emails

Unfortunately, these signs arent always a clear indication of malware infection. There are many other possible reasons for your computer acting up. Just like a headache can be a sign of sickness, dehydration, muscle tension or other problems.

What Are The Signs My Pc Is Infected

If you notice that your search engine, browser homepage, or even desktop wallpaper have changed without you doing anything, it may be time to run a scan as described above. Other symptoms could be your computer running hotter or slower than usual or seeing popups or notifications that you havent seen before.

How Do Viruses Get Into Pcs
Computer viruses typically spread in two different ways. The most common way is by getting people to open infected files. Those files could be sent via email, downloaded from websites or on removable storage such as a USB stick: if you open the file, the virus sneaks onto your PC or Mac.
Viruses can also be transmitted via insecure software, which is when a program isn’t 100% safe from infection: some viruses are written specifically to target vulnerabilities in specific programs.
Can Your Computer Become Infected With A Virus Via Email
Your computer can become infected with a virus via email, but only if you open attachments within a spam email or click on the links contained in them.
Simply receiving a spam email will not infect your computer. Just mark these as spam or junk and ensure they are deleted. Most email providers will automate this but if any slip through the net, just mark them as spam yourself and dont open them.

How To Stop Viruses Getting Onto Your Pc
The last thing you want is another infection, so it’s important to practice the internet equivalent of social distancing: never open files you haven’t specifically requested and never download files from places you don’t 100% trust.
We’d strongly recommend good antivirus software no matter how careful you are. Many of the best antivirus software suites will automatically scan incoming emails, files you download and USB devices you connect but they’ll also protect you in other ways too.
For example Norton AntiVirus has anti-ransomware protection and virtual private networking to prevent people from intercepting your data when you’re using public Wi-Fi, and it has parental controls so you can ensure the kids browse safely too.
Not every virus is obvious and not every virus spreads in ways you can anticipate, and new viruses are discovered every day. Good antivirus knows about them too.
It’s also very important to keep your copy of Windows and your other apps up to date. In most cases that should happen automatically via Windows Update and your apps’ own automatic checking for updates, but not all apps do it for you so make sure you click those “check for updates” buttons.
We’d also recommend two other very important things. One, make sure you backup anything important. Viruses aren’t the only threat to your important files: hardware can fail, laptops can be stolen and accidents can happen. If it matters to you, make sure you have backups of it.
Run A Malware Scan On Windows 11
Windows Securitys built-in virus and threat protection feature.
To do this, go to Windows Security > Virus & threat protection, and click the Quick scan button. If you want to do a more thorough scan, which will take longer but will check all your files and running programs, you can instead click the Scan options button, and choose Full scan.
If Windows finds malware during the scan, you can click the Start actions button to begin the process of removing the virus from your computer.
If the scan doesnt turn up anything, youll just see a report about how long the scan took, how many files were scanned, and when the scan took place.

How To Spot The Symptoms Of A Pc Virus
PC viruses are like real-world viruses: they attack your PC and prevent it from working properly. So the first sign of a PC virus may well be your computer doing unusual things. Are you suddenly seeing stacks of pop-up adverts? When you try to search the internet, do you get weird results? Are you locked out of your computer altogether with a message demanding money?
These are all what computer experts call ‘malware’, which is short for malicious software. Each one is a slightly different kind, so the one that blasts you with adverts is called adware, the weird search results are the result of what’s called browser hijacking and the locked computer is called ransomware.
In the case of ransomware, never, ever pay the ransom or even worse, give the criminals your card details or bank details: they probably won’t unlock your PC but they’ll definitely make off with your money.
Although many viruses are obvious, some of them aren’t. Some of them are only obvious to other people. For example, if you get messages from friends, family or colleagues asking why you’re sending them weird stuff, that’s often a sign that a virus on your computer is sending out infected emails to try and spread to everybody in your contacts book.
The good news is that all of these problems are easy to fix.
