Thank you for that information. I put them all in a folder and will keep them on an external drive for now. Will delete them later.

I checked the 12 files (some duplicates) and found that they are all windows installation programs of some sort like: migwiz.exe, i2omp.sys, key find.zip, 1ad367.msi.... So I don't understand how those programs would end up on my iMac, but I got rid of them.

Well, I stopped my subscription to the Intego VirusBarrier program package, since it wasn't working anyway. Then later I was on the App Store and saw Intego VirusBarrier. It was free so I downloaded it and it worked. I have 12 malware programs in Quarantine now. They all appear to be windows based apps since they are mostly .exe and .sys programs with one .msi and a .zip program. That's a little unsettling. I send emails to people who use Windows and would hate to pass those along.

Thank you for the response and the information!

I have used Malwarebytes Premium for a couple of years now and it appears to work just fine. I also have been running Intego VirusBarrier for about ten years now. They have worked together just fine. About a month ago, the Intego program stopped scanning. It would start and then go on forever not scanning, all other functions of the program appear to keep working, including download antivirus updates. I asked Intego about it and they said to uninstall Malwarebytes and try it again. That made no difference. Daily for two weeks I have been working with Intego and still nothing works. Now they don't respond to my questions. Which brings me to my question, is additional anti-virus software necessary? Does Malwarebytes have an antivirus capability? Intego's package includes malware detection in addition to their antivirus software but don't know if that is just for show or not. Thanks
