Re: Unknown error received from scanners

Jump to solution
If we're receiving the error 1048 - Unknown Error, after doing research all it means is that the On-access or On-Demand scan is unable to scan that specific file, whatever it may be. Whether it's a .dmp, .tmp, .mnt etc. So until there's an update for ENS to scan certain file types it may be better to try and exclude that specific file.

For example if you go to System Tree > Find a System > Pull up its Threat Event Logs and see:
ID: 1048 - Scan reports general system error, open this event to view which file it had an issue scanning. I pull up an event like this and see ENS had an issue scanning:
Threat Target Process Name: /bin/gawk
Threat Target File Path: /root/shoudbe.out

We now have the ability to exclude this specific file path / process if we want, but it's up to your discretion. If we exclude it this event will not be recorded for that file / path or process.

I hope this helps. Let me know if you need more insight.

After launching a scan,  "unknown error received from scanners"  appears after about 3 seconds, but no files were scanned.

The computer is an iMac running Mojave 10.14.5.

I don't understand the fixes I have read prior to my post : the iMac is my wife's computer. I'm used to debugging Windows, not Apples, so please excuse my ignorance in this matter. I looked for System tree, but could not find it (in case that's the path toward uncovering the fix).

What are step by step instructions to make McAfee functional on the iMac Mojave?

Thank you.

Hello @dagflorida

 

No problems, how do you manage your scans? Is it an enteprise license where you use the ePolicy Orchestrator to manage systems, or is it personal licensing? I ask because ePO is where you would find the system tree, if you're seeing these issues on a personal license I'm unsure how this might be resolved as I'm unfamiliar with their interface.

 

However, if you know how to add exclusions on the personal version of McAfee's AV, I'd do that. Add an exclusion for the directory / file type that is seeing errors. This should resolve that issue.

 

If you're able to answer what product licensing you have I could definitely try and help clarify things further. Hope this helps!

 

Best,

Zach

Thanks, Zach.

The iMac with the scanning issue uses McAfee LiveSafe personal license.

I am a Windows user since DOS and Windows95 so I am young and stupid regarding debugging an Apple product.

But, I'd love to know the clickstream to be able to attempt to fix this issue on my wife's iMac.

1. How to locate the directory /file that is seeing errors?

2. How do I add an exclusion for the directory / file type that is seeing errors?

Can you point me to the appropriate place for instruction?

Thanks very much!

Zach:

I didn't realize that I wasn't in the  Livesafe forum for personal users.

I'll  submit my questions  there.

Thanks
