Apparently, I have managed to get a pop up ad virus in Safari. Almost every time I click on a legitimate link in one window or go to a new web site, a new window opens either with some ad, a warning that Flash player is corrupt or needs updating, or "Your system is corrupted with 3 viruses". Very annoying.

I am using a mid-2010 iMac running the latest OS allowed - version 10.13.6. No jokes, please. I'm 73 and my computer needs are minimal. It is serving me just fine for now, except for this issue.

Here's what I've tried so far:
1. Checked Safari Preferences/Security to make sure "block pop up windows" is selected
2. Ran Disk Utility
3. Ran Onyx
4. Reinstalled the OS

My question: Is there any way to get rid of this virus without having to spend money to do so? Any other suggestions?

If not, what is a reasonably priced good piece of software that you recommend?

Your help is most appreciated. TIA

Ralph

Check Safari Extensions for something undesirable. (Safari Prefs -> Extensions (tab) )

You may have been tricked into installing one at some point. Also check your "home page" setting, to see if it leads to an ad-serve page.

Good suggestions. As for undesirable extensions, there are only two: Amazon Assistant and Honey.

Home page was checked as well and it's what should be there. Just recently, when I start Safari, my Home Page isn't loading. I've tried deleting it and resetting it to no avail. This started after I reinstalled the OS.

Disable both extensions, relaunch Safari, see if that fixes it. If it does, narrow down which one. My guess would be Honey. If memory serves, it's a find-the-best-price plugin. Which would require checking outside servers.

You can also try another browser (Firefox, Chrome, Opera, iCab, Omniweb) to confirm the problem is limited to Safari.

I have amazon assistant and know lots of people use Honey. If they were bad surely the internet would be abuzz?

Clearing cache and history wouldn't hurt.
Sophos antivirus is free, IIRC.

Uninstalled both extensions, restarted the computer and found that the problem was still there.

My wife uses Firefox on this same computer and isn't having the problem.

I just tried Malwarebytes and, crossing my fingers, it seems to have gotten rid of the problem. Let's hope it remains that way.

Thank you all for your suggestions. They are greatly appreciated. I will keep this thread in mind should my issue returns.

What did Malwarebytes find? Did you save its log?

I haven't heard of this problem before. Knowing the cause would be helpful to the next person.

I didn't save the log - BUT - I didn't delete it either.

Below are the results of the Malwarebytes scan. It doesn't allow changing window size to include all the results, nor does it allow doing a print-out, at least in the free version, so I did a bottom and top half screen shot.

If you see something that should be restored, please let me know. Likewise, should you be able to identify the culprits, please advise.

I don't know any of those off-hand. The dangerous ones are the files in:
/Users/Ralph/Library/LaunchAgents/

.plist files in ~/Library/LaunchAgents/ launch apps when you log into your account.
No examples are shown, but .plist files in /Library/LaunchAgents/ (or LaunchDaemons) launch apps or services when you boot up.

Another place to check is System Prefs -> Users & Groups (formerly Accounts) -> (your user name) -> Login Items

Hmm, sounds like MacShiny is one of the culprits... a fake "cleaner" app like MacKeeper!
