"Your system is infected with (3) Viruses” when opening a Safari tab

Hello, your English is good enough...

Malwarebytes…

https://www.malwarebytes.com/mac/

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Absolutely not, and reading at least the first page of this thread before posting would have told you that and saved you asking. No-one can detect a virus remotely, even if there were any on a Mac or iOS device which there aren't. Never ever respond to unexpected emails or pop-ups of this sort.

in almost all messages about SPAM you can read what to do:

Quit Safari,

then open Safari whole holding the Shift key,

Safari->History: clear all history,

Safari->Preferences->Advanced: check the "Show develop menu..." at the bottom.

Safari->Develop: select "Empty Caches".

after this the spam should not come on after this.

but I won’t get rid of Norton!

All AV software, of any kind, is 100% useless on iOS devices.

1. There are no Mac or iOS viruses. None. Zero. Nada. There's nothing to look for.
2. iOS is a locked down system that is almost impossible to infect with anything.
3. AV apps in iOS are even more useless than those touted for the Mac. Because all apps are sandboxed in iOS, the only place any such software can look for malware is within itself. Totally, friggin', useless.

All AV software on the App Store for iOS is garbage. Pure and simple. Apple actually stopped allowing any more to be added. What's there is allowed to remain only because it was already available before the new rule went into effect.

An Apple rep suggested the free Malwarebytes software to clean the computer. I used it it this time and it quarantined and removed the virus. There is a pay version, but the free version works fine.

Yes, MBAM is a useful tool to remove the Adware that you installed. It is much easier to just not install Adware.

You assume correctly. There is no possible way for anyone to know what's on your system through a web browser. 1000% less than that via a message or text. How could anyone possibly do that?

A message like that is no different than me sending you one that says you have polio and have been assigned to the next manned NASA space launch. It's meaningless drivel.

I have this same problem. this is my first MacBook so I'm not sure if this is normal. I don't think I visited any shady sites.

If you’re connected to the internet, you can and will see scam ads, scam postings, scam email.

Even on so-called “reputable” websites, the ad networks integrated into those websites routinely serve scam ads. Ad networks can and variously do load dreck. And ad networks can and have been compromised, and will try to load yet worse dreck.

More than a little of the email we receive is scams. Sending email addresses are routinely spoofed / faked / forged.

More than a few telephone calls are scams. And calling numbers are routinely spoofed / faked / forged/

And if the “entrepreneurs” that posted whatever text you’re reading here could actually have scanned your system for malware—scans are seriously intrusive—they’d just upload all your data and your contacts and be done with it. Remote websites cannot scan your computer or your phone. That’d be a massive security vulnerability.

it’s easier to hack people than computers, too. You and I. Not our computers. Not our phones. Us. Here are some of the many ways we ourselves—not our phones and not our computers—get hacked:

This looks like a fix for a Mac, but what if it happened on an iphone? Hiw can I fix?

Thank you

Same answer. These folks hacked YOU. They fooled YOU. They want to scam YOU.

They don’t care about your Mac or iPhone or iPad.

They’re just lying about hacking your Mac, or iPhone, or iPad, or Windows.

BTW: This is how propaganda, and some political campaigns work, and how some advertising works. They get you to believe in manure, then you do something against your best interests.

These folks cannot scan your Mac.

These folks cannot scan your iPhone or iPad.

These folks cannot scan Windows computer.

Malware scans are very intrusive. They have to access everything. So intrusive that malware scans cannot be done by apps already loaded on iPad or iPhone, much less remote. Apple blocks that scan on iPad and iPhone, even locally. A remote scan of your files and documents and everything from a random website would be a security catastrophe.

And if the scammers could do that intrusive scan (they cannot), they’d just swipe everything directly, but your web browser blocks that access. They wouldn’t bother trying to get you to load their apps.

Grumble at the website maintainers, or don't visit the website.

An ad-blocker app might help, if it's arising from buggy or scammy ads.

But somebody is going to have to rummage, and that's usually going to the the website maintainers.

Others might or might not get the same ads served or the same contents or the same content delivery caching, so these can be less than fun to debug across different users.

I received this message today - (3) Viruses have detected on your iPhone and battery has been infected and damaged. If you do not remove this malware now, it may cause more damage to your device, How to fix this:

Some reading at the following link: Scam Pop-ups, Scam Viruses, Scam Receipts… - Apple Community

Surprised they don't suggest screen mange and display burn-through and electronic fleas to go with that battery infection. They should offer a special salve for the itching, too.

The scammers will continue to make and test changes to their messages of course, seeking to convince more folks to perform whatever activities the scammers might seek of them.

I need these virus gone please.

Congratulations, the reported “viruses” never even existed.

The advertiser that wrote that pop-up lied.

There’s nothing to be gone. Nothing to be done.

Enjoy!

I am still worried, but I don’t know if it did anything

Have you read any of the replies, here?

It can't do anything. Clicking on a link can't do anything to your Mac.

You have to actively install malware onto your Mac. It can't magically get there without you running the installer and allowing it to be there. Clicking on a link might initiate a download, but you would still have to actively run the installer.

It can't "scan" your Mac. It can't even see your Mac. It knows nothing about your Mac except the external (public) IP address, the browser type, and the OS type. All of that information is sent with every HTTP/HTTPS request.

I have one or more viruses on my system. Can someone tell me how to remove them please?

You have zero viruses. None. Which means there’s there’s nothing to fix. You were lied to by an advertiser’s pop-up ad.
