The antivirus software will usually do this automatically, but it's a good idea to use its "Check for Updates" option to be on the safe side. New forms of malicious software are found every day, and the best antivirus apps are constantly updated so that they can destroy even the most recent viruses. The second thing to do is to isolate the virus so it can't do any more damage. To do that, you can put your PC into something called 'Safe Mode'. This is a feature of Windows that runs with the absolute minimum of features.
That means there are fewer opportunities for the virus to do anything or to spread to other computers. Once you're in safe mode, run your antivirus software and put the kettle on: no matter how fast your PC, scanning everything on it can take a little while. Your antivirus software will identify any infected files and clean them if it can; if they're beyond repair, it will quarantine them so they can be safely deleted without re-infecting your PC.
In some cases you can also use Windows' System Restore to roll files back to their pre-infection state. 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 VPN 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. Are you unsure of how to do this? Some viruses are programmed to initiate when your computer boots up. Deleting temporary files may delete the virus. However, it is not safe to rely on this. To ensure you rid your computer of viruses, it is wise to complete the following steps.
Now it is time to run a virus scan using your chosen anti-virus or internet security software. If a virus is found, it may affect multiple files. If threats are found, quarantine or delete the files. Now that the virus is removed, you can reboot your computer. Simply turn it on as you would normally. To protect your computer from further attack, change all your passwords in case they were compromised. This is only strictly necessary if you have reason to believe your passwords have been captured by malware, but it is better to be safe than sorry.
Updating your software, browser and operating system will reduce the risk of flaws in old code being exploited by criminals to install malware on your computer.
If you use a Mac, you may be under the impression that your computer cannot get a virus. Unfortunately, this is a misconception.
There are fewer viruses that target Macs compared with the many that target PCs, but Mac viruses do exist. Some Mac viruses are designed to trick users into thinking they are anti-virus products. If you accidentally download one of these, your computer may be infected. If you think your Mac has a virus, here are six steps to follow to remove it:. To ensure nothing is missed and to keep your Mac protected, consider installing a running an anti-virus solution if you do not already have one.
We recommend comprehensive internet security solution like Kaspersky Total Security. A computer virus is a type of malware malicious software designed to make self-replicate, i. Computer viruses are so-called because, like real viruses, they can self-replicate. Once your computer is infected with a virus, this is how it spreads.
When a computer virus infects your computer, it may slow it down and stops it working properly. There are three main ways that your computer may have become infected with a computer virus. The first way your computer could become infected from removable media, like a USB stick. If you insert a USB stick or disk into your computer from an unknown source, it may contain a virus. Another way your computer become infected with a virus is through a download from the internet.
If you are downloading software or apps to your computer, ensure you do so from a trusted source. Avoid downloading anything via a pop-up or a website you do not know. The third way your computer could become infected with a virus is if you open an attachment, or click on a link, in a spam email. Whenever you receive mail from a sender you do not know or trust, avoid opening it. If you do open it, do not open any attachments or click on any links. While hackers are continuously creating smarter and more advanced viruses, there are several ways to protect your device and files.
The best way to deal with a virus is to prevent it in the first place by using antivirus protection and antispyware software. Regularly back up your files to the cloud or safe external hard drive in case they become corrupted, ransomed or are deleted. Use a security tool to evaluate your device and find out how vulnerable it might be. Your browser may warn you about suspicious websites, or you might see a red unlocked lock to the left of the URL at the top of the webpage if it is unsecured.
Another good rule of thumb is to never open an email or attachment unless you know and trust the sender. Be very careful when downloading software. Only download programs, movies and music from legitimate websites or services.
Many people connect using public Wi-Fi in cafes, restaurants or stores, but these unsecured networks can leave your phone, tablet or computer susceptible to viruses. Instead, consider using a personal hotspot to connect to the internet.
Finally, educate yourself about the types of threats out there and teach others to do the same. If you think your computer has been infected, start by running a full system scan using your antivirus software and an anti-malware program. Review the threats and take any action that you can the software should guide you through this.
