Greetings and salutations,

I visited RARBG and since then, I've been experiencing rather unusual behaviour by Norton repeatedly giving me notices they've blocked traffic to a dangerous or infected ad page with a message "resolved", and a "I don't have to do anything", all in one window. So next, I used "AdwCleaner" tool which removed something with a PUP or a PUA name attached. I couldn't tell you what or which it was, because I forgot to save the text file. However this didn't work and more repeated blocked traffic messages from Norton ensued as soon as I launched Firefox after restart.

 

Next, I did a System Restore to a week Wednesday. I launched Firefox without issue. So I presumed everything was OK, but to be safe, I did a scan with Malwarebytes which revealed, NOTHING, and a Full System Scan with Norton which revealed a potentially nasty (???) adware, PUA.JScoinminer.

 

I've been reading about its variant (???) "Ethash Trojan.CoinMiner" and how it can bury itself deep within the system infecting everything. This can make it very hard to remove completely I would imagine. And although reading on PUA.JScoinminer which doesn't seem all that harmful like "Ethash Trojan.CoinMiner", it really has me worried, and especially because, this was found on another Windows User which l had last accessed weeks ago. So who knows how much information was gathered, maybe. Please help me remove this completely from my system.

Thank you!

I'm getting the following messages from Google.
 

"Unusual traffic from your computer network"
If devices on your network seem to be sending automated traffic to Google, you might see "Our systems have detected unusual traffic from your computer network."

Hi. I could not find anything wrong, but I'm no computer expert, so maybe you could see if there's a problem? Repeated Malwarebytes and Norton scans have revealed nothing, so maybe all is okay then? :scratchhead:  Or at least it would have been. But since I last used the FRST thingy, internet speeds have taken a severe knock from what its was before at 6mps, and is now maxing at 1.3mps or above 350kps avg and it has not improved since. System restore is out of the question and methods to get back that bandwidth; p2p traffic, blog-site guides etc. sigh

 

:killcomp: On the verge of giving up!!!

That's why I want to get the deeper look. These other tools may not show something deeper.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 3 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
