McAfee_Vulnerability Scanner_Java Runtime Environment update

Hi Vishnu. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

I would uninstall Java from Settings > Apps > Apps & Features and only reinstall it if you're prompted that an app needs it, and maybe even reconsider using the App since Java is a real security risk.

No expert in Forums - where we see the most cases, by the thousands - recommends Avast, AVG. Norton or McAfee, but we have solved many problems over the years by having them uninstalled.

I would uninstall any 3rd party antivirus in Settings > Apps > Apps & Features and try running only built-in Defender which gives adequate protection, best Windows performance, least issues, and is from Microsoft who knows how to protect their OS best.

After uninstalling antivirus in Settings > Apps > Apps & Features, restart the PC, then type Security in Start Search, open Windows Defender Settings, there and in Windows Defender Security Center fix anything that's flagged.

If you want the best on-demand scanner download and install Malwarebytes from https://www.malwarebytes.com/mwb-download/
In it's Settings > Protection > Scan Options enable Scan for Rootkits.
Then on Scan tab choose Threat Scan and Run Scan.
Clean up anything found, restart PC and then run again until it comes up clean.

If you want to keep Malwarebytes as an on-demand scanner then you can disable its Real Time trial version in it's Settings > Accounts tab.

Next check for damaged System Files since the problem anti-viruses can damage WIndows: https://www.lifewire.com/how-to-use-sfc-scannow...
If it cannot repair them see Step 10 here to continue: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and keep me posted. If you will wait to choose if I solved your problem, I will keep working with you until it's resolved.

If you are going to uninstall 3rd party antivirus program go to the maker and get their removal software to completely remove all the code.

(Sorry, no vain boasts of expertise from me.)

McAfee is excellent antivirus software, and it ranks highly among the professional testing organizations ... the real experts in antivirus software.

If you already have the Java Runtime Environment installed on your computer, it may well need an update, so McAfee is right. However, you should know that Java as a technology is not secure for internet-facing applications, and for that reason it fell out of favor years ago.

Unless you have a compelling reason to have the JRE on your computer, you really should not have it at all. Rather than updating the JRE, you should uninstall it. You will lose nothing by uninstalling it, and you will be much safer.
