Hi everyone this is my first post! Happy to have found this forum. I'm just starting to learn about malware removal. My main question is should I join AlienVault Open Threat Exchange? I'd like to be able to more easily identify threats that are found on my devices and network. The website is https://otx.alienvault.com . I'd also like to learn how to identify who an IP address belongs to and if it is safe. Below are details related to the malware on my iMac (Mojave 10.14.6. If anyone cares to delve in and comment on any of it, that would be fantastic. Thank you in advance. My Safari (v13.1) cache has 50+ websites in it that I have not navigated to, and if I delete each cache individually, some automatically come back. I've looked into a few of these cached sites, but am extremely hesitant to continue to go to these websites or even to google them to investigate because it may raise my risk of getting infected. I've run EasyFind (Devon Technologies app) searches on some of the websites in the cache, and it is not finding them despite searching all files and volumes. 1st run of the Premium trial of Malwarebytes found Crossrider, mitmproxy, a browser extension in Chrome (adware), several files and directories related to TopicLookup, and a couple other files and directories. Screenshot attached of quarantined items. Nothing else found since then and my trial has run out; should I upgrade to Premium? Flash Player was installed and updated multiple times from a 3rd party. This was over a year ago; I don't remember doing it but it updated monthly for some time. Adobe cannot find it on my iMac to uninstall it; I'm assuming that is because Flash Player was not installed from Adobe to begin with. I've started to manually find and delete the Flash files. Deleting Flash Player from the system preferences pane requires me to put in my admin password, which I haven't done yet (again, hesitant). EtreCheck report below. I am new to EtreCheck and am still deciphering the report. I have a runaway process and kernel panics that could be related to 3rd party software. Also, I downloaded Norton from my Internet provider (xfinity) on 4-9-2020, and EtreCheck shows Norton for Mac and Norton Security were both installed. The app is Norton Security; I can't find Norton For Mac anywhere on my iMac. At any rate, Norton Security has been useless in finding threats. EtreCheck version: 5.5.4 (5106) Report generated: 2020-04-28 03:34:46 Download EtreCheck from https://etrecheck.com Runtime: 2:04 Performance: Excellent Sandbox: Enabled Full drive access: Enabled Problem: Other problem Description: Remove Flash Player, adware, malware Major Issues: Anything that appears on this list needs immediate attention.
