Hello!

I've been having trouble with some kind of virus lately. I'm not sure of its exact nature, but I definitely believe I'm infected. I am on Windows 10.

Issues/symptoms include:
- Firefox slowing down when typing, or when using sites like roll20.net.
- Entire computer locks up one program at a time until everything's frozen and stays frozen until a point where everything un-freezes. I believe disk usage shoots up to 100% when this happens. The programs tend to only freeze when they need to "load something new", if that makes sense. I'm unsure if this particular issue is related to the virus or not.

- At some point I received an obviously fake pop-up for a Firefox update, and my search engine was changed to Yahoo.
- At some point, a branch of Chromium was installed on my computer and was set to launch by default on startup.

- On occasion, the Firefox WebIDE will open up by itself, entirely unprompted.

- At some point, I saw a CMD window pop up along with the WebIDE and it said something about making a daemon process.

 

Troubleshooting I've tried:
- Running Malwarebytes (no dice - doesn't pick anything up.)
- Running Hitmanpro

- Running AdwCleaner

- Running CCleaner

- I found a folder called "Wincy" in Appdata (local I believe), it seemed to be nothing but suspicious so I deleted it.

 

 

I ended up needing to fully refresh Firefox for the symptoms to stop, but the WebIDE opened back up by itself again earlier, and as I was typing this post, the WebIDE opened itself once more. so I guess I'm still infected. Any advice would be appreciated. :)

Welcome to BC...

 

Start a new topic in the malware removal forum by following the instructions below.

 

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.

  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.

When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

 

DO NOT bump your new topic. Wait for a response from one of the Team Members.

Not sure if I should bump this thread or start a new thread, but I believe this issue is plaguing me once again - the Web IDE popups are happening again. The removal steps provided last time worked, but I would assume fresh logs would be required for removal steps, and I would appreciate help in taking care of it again. I figured out what download I was doing has caused this issue, so I'm hoping to avoid it going forwards. Help would be appreciated!

snip

Sorry, I posted that and then PM'd a moderator about it. I missed the part about contacting within 5 days. The issue was initially resolved by the steps Nasdaq posted, but it came back after I installed some software (now I know what software install is causing this issue, I'll avoid it in the future!). I'll simply make a new thread. :)

Please pursue that topic to exhaustion.

 

This topic is now closed to avoid confusion.
