Just got update from Bitdefender that protects from ransome-ware. It shows the eoptcron wants to write to protected files. Can not find anything on eoptcron. Anyone know anything about this application? It is a hidden file in /ueser/.
Thanks...
Denny
MacBook Air, OS X Yosemite (10.10.5)
I ran my macbook air and my wife's for two years. I had bitdefender and she had nothing. He machine started to run slow and had all these adware popups. I installed bitdefender and it found most of them. There was one or two I could not find/delete. At the advice of one of these forums, I ran Malwarebytes. It cleaned up the remaining issues. Runnig the new version of Malwarebytes did not find malware.
I do not believe for an instant that Macs are immune from attacks.
Long way around, but I figured that was the case. I no longer use Optimum, had to change ISPs.
When the new function of Bitdefender came up, it displayed a message saying that access to write is denied. It also had a checked box saying it was Apple Certified (or something similar).
If I block the app in Bitdefender, I get constant messages saying "write access denied for this application" and then lists eoptcron. I can unblock it and, obviously, no more messages. I think it is stopping a write to /users/me/documents
I am "happy" that this is apparently not malware, but would like to get rid of it. I don't think it's huge, but this could be a performance hit.
There is a cvcoptdata folder in documents, but it is not hidden?
Never heard of eoptcron but know of Bitdefender. The best advice I can give you is to uninstall Bitdefender as per the developer's instructions. No anti-virus or so-called "cleaning" apps are necessary or recommended for Mac OS. They can interfere with your Macs built-in protection. At best they cause a hit to performance and at worst will bork your system.

To add to that there are posts, often daily where Mac owners are running into performance issues or worse and after diagnosis removal of whatever AV product for mac they were coerced into installing was the cause of the problems. At this time they are counter productive and unnecessary on Macs.
Macs can get adware but not if you are careful. Most malware requires authentication by the user. Others can bypass that if you are running torrents. The malware can be delivered in the download and you'd never know it's there. This is also the case with phony FlashPlayer installers and some cleaning apps, which is why they should be avoided.
Malwarebytes is safe and does not need to actively scan your system, using unnecessary resources. So, if you do get malware, it's the best way to remove it.
I'm giving you the best advice I know when I say to uninstall Bitdefender, you can choose to disregard it. But before you do run Malwarebytes and see if it reports the same as Bitdefender. AV apps are also known to produce false positives.
I understand your advice. I plan to keep running bitdefender. It found potential intrusions in the past and does not appear to impact my Mac.
However, my question still has not been answered. I keep looking and it seems to have something to do with an Optimum (ISP) app that lets you watch TV on your Mac. I found some code with it and it is trying to write a token to cvcoptdata. cvcoptdata folder is in my documents folder. That folder seems to be safe per Apple Support. In any case, before I erase it, I still would like to find out what eoptcron is/does.
If I delete bitdefender, eoptcron will still be writing stuff to something on my Mac.
I did a search before I replied you and I found the same, that it's associated with Optimum but that's as far as my knowledge goes. Hopefully, someone with more insight on the issue will come along. I agree with you about not allowing an operation until you are sure what it does.
Hello Denny,
It is the "Optimum App" for watching TV or something. Although this app does not appear to be adware or malware, it does act very suspicious. Can you provide more information about what Bitdefender is actually saying?
It looks like the optimum app has a launch agent named "net.optimum.iptv.optimumapp.agent.v3.plist" in your user launch agent directory at ~/Library/LaunchAgents (in Finder, choose Go > (hold down option key) > Library). It creates a hidden directory ".cvcoptdata" in your Documents folder. The "eoptcron" executable is inside this hidden folder.
Thanks a ton. I figured out how to display hidden folders and there it was! eoptcron was the only app there. I deleted the folder and deleted cvcoptdata in documents.
It no longer shows up in "Manage Applications" in bitdefender "Safe Files".
Thanks again...
Denny

And no one here so far has suggested that. What was stated is that the forums are littered with OS X issues that are entirely the fault of poorly implemented, under developed and erroneously reporting products that have nothing to do with their far better funded and coordinated Windows counterparts. Macs running OS X could possibly become infected virus; so could your kitchen blender if it's connected to the internet; but at this time no credible or independent securities lab in the world has discovered a Computer Virus by definition that infects OS X at this present time in the wild.
Despite whatever claims these products make these forums point conclusively that most if not all of these products are causing far more damage then they purport for fix. They are often misleading in both identifying threats or worse yet; instructing users to perform modifications that cause further problems.
I disagree with your statement. In one of the initial responses it was stated;
No anti-virus or so-called "cleaning" apps are necessary or recommended for Mac OS. They can interfere with your Macs built-in protection. At best they cause a hit to performance and at worst will bork your system.
I read this as if "cleaning apps" such as Bitdefender, etc are needed, then the Mac is immune.

Hello dennyjd01,
No. "Cleaning apps" are a different category. BitDefender is an anti-virus app. That is also something that people here on Apple Support Communities are unlikely to recommend, but for different reasons. Your post is one of those reasons. Apparently, BitDefender has added some kind of real-time disk I/O control feature. So, when someone posts about some problem where something is mysteriously not working, and they have BitDefender, that is yet one more reason to recommend uninstalling it. Perhaps it isn't related to whatever problem is being discussed that day, but there is no way for us to tell. After a while, removing antivirus apps like this becomes an automatic response to any problem. Such is life.
Also - I am no longer on Optimum. Moved and now use different ISP.
anybody know what eoptcron is?
