Malware making Mozilla think all Websites are "unsafe"

So the title says what the problem is/was. I downloaded (yes it was a huge mistake) a crack of a program, which gave me a big load of malware, which I could delete with malwarebytes for the biggest part, but theres still a file thats confusing me. It's called "a046f42f740043fb0c2f828a55297521" and includes a few files, such as a cleaning or video editing tool, but the weirdest one was an executable file which I dont remember the name of, it was also just a combination of random letters and numbers. What it did is that it kept opening itself as a background program, and it made Firefox see every website as dangerous, thus i wasnt able to access them (I was able to close it with task manager, but after some time it re-opened itself). Deleting the folder just led to it coming back (in my programs folder) and the same thing happening again. I let malwarebytes analyse the folder and it deleted all files except service.dat and the executable file. After deleting the .exe the problem stopped happening, but this in general just seems a little confusing to me, so I'd be glad if anyone could help me and explain what exactly this is.

Check to see what your DNS is set to. I've seen issues where using a different DNS causes a boat load of issues.

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.
