    How to Check for Viruses on Your Computer

Built-in features like XProtect do help, but they dont match up to dedicated antivirus software.

    There are two main types of protection you need to use. Antivirus scans and real-time protection. Scans can be carried out manually, searching your entire Mac or chosen folders for malware. Real-time protection is always on, and if you download or try to run a virus, it kicks in and lets you know.

    Heres how to run a virus scan in MacKeeper:

    1. Open MacKeeper, and select Antivirus from the sidebar

    2. If you want to scan certain folders only, click Custom Scan

    3. Otherwise, click Start scan

    4. When the scan is finished, select any detected malware, and you can either delete it from your Mac or move it to Quarantine.

    Protect Your Pc From Prying Eyes

    Regardless of how cautious youre, you cannot completely eliminate the threat of computer viruses. Use these methods to counter malware threats and protect your valuable data from prying eyes.

    And if the above methods dont suffice, there are many other antivirus tools to further solidify your PC’s defenses.

    Revert Reboot Scan And Re

    If you’ve got System Restore points set in Windows, when malware attacks and can’t be fixed, use this opportunity to reset the system. It could do the trick…but probably will not. The malware may be too smart.

    You can reboot directly to the built-in Microsoft Defender that comes with Windows 10. To do that, go to Settings > Update & Security > Windows Security > Virus & threat protection.

    Once Windows Defender is activated even for just periodic scans, look for Scan Options. Click it and check the box next to Microsoft Defender Offline Scan. After a reboot, it’ll do about a 15-minute scan to look for “rootkits and other highly persistent malware,” according to Microsoft.

    Still feeling infected? If you’ve got a remote access trojan aboard your PC, potentially someone is remotely accessing your PC. That’s bad news. Likewise, if you’ve caught some ransomware, you don’t want it encrypting files you back up to the cloud automatically. Take a deep breath and get off the internet. Pull the Ethernet on the PC, turn off the Wi-Fi, unplug the router if you must. Guarantee the PC is disconnected. Make sure it’s not using Wi-Fi from a neighbor or nearby business to stay online on the side. Then, attempt some antivirus scans.

    Didn’t work? Reboot Windows again, but in a way that won’t let the malware get restarted as well. Try going into the minimalized Windows 10 interface called Safe Mode . Run a scan from there and it may work.

    What Are The Signs Of A Virus

    How To Check For Viruses On Mac Computer

    Poor performance, application crashes, and computer freezes can sometimes be the sign of a virus or another type of malware wreaking havoc. However, thats not always the case: There are many other causes of problems that can slow down your PC.

    Likewise, just because your PC is running fine doesnt mean it doesnt have malware. The viruses of a decade ago were often pranks that ran wild and used a lot of system resources. Modern malware is more likely to lurk silently and covertly in the background, trying to evade detection so it can capture your credit card numbers and other personal information. In other words, modern-day malware is often created by criminals just to make money, and well-crafted malware wont cause any noticeable PC problems at all.

    Still, sudden poor PC performance may be one sign you have malware. Strange applications on your system may also indicate malwarebut, once again, theres no guarantee malware is involved. Some applications pop up a Command Prompt window when they update, so strange windows flashing onto your screen and quickly disappearing may be a normal part of the legitimate software on your system.

    Theres no one-size-fits-all piece of evidence to look for without actually scanning your PC for malware. Sometimes malware causes PC problems, and sometimes its well-behaved while sneakily accomplishing its goal in the background. The only way to know for sure whether you have malware is to examine your system for it.
