    Remove " Warning! Your Computer Is Infected"  fake alert (Support Scam)

    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.

    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

    Remove the Your Computer May Have a Virus Web Page

    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

    How to Remove Viruses From Your Computer

    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.
