Serious Virus (Yahoo! Powered)

Recommended Posts

Ok, So I've been having a huge problem during my vacation. I was downloading a file from mediafire. I have had past experiences with this domain before, and I've encountered pop-ups more than a few times. I decided to risk it, not knowing it could've really infected me. It redirected me to a webpage that was completely unknown to me. My anxiety appeared, so I closed it. I was shaking and sweating, I honestly didn't know what to do. I left it for a while, and then came back to it. I opened my control panel and found a program under the name of 'Yahoo! Powered'. It had no information on it's publisher, size or version. I decided to google it, and I came across lots of different opinions. People were saying it was just Yahoo, others said it was spyware. If it is spyware, I would be petrified. It has an uninstaller, but it looked pretty fake. I downloaded ESET NOD32 Antivirus, It found it but didn't classify it as a threat. I had MalwareBytes, but my dad told me to remove it, as he doesn't trust anything. I love your software, and I got rid of two trojan droppers from my computer (Thanks guys :) ) and I also have something called $RECYCLEBIN. If anyone can help me, please leave a response! Thanks ;)

Hey, got a bigger problem. I did a scan with ESET NOD32 Antivirus, I found viruses, but.. It doesn't classify them as viruses? Now, you're probably asking how I got them. And I'll tell you, I downloaded custom content (cc) for my Sims 4 game, the download link directed me to Mediafire and I clicked the download button. It redirected me, and I found Yahoo! Powered in my control panel, just an hour ago I found: $RECYCLE.BIN, win_console_handler.py and lastly: c:\ProgramData\Microsoft\Crypto\RSA\MachineKeys    Please tell me how to fix my computer, i've only had it for a few months, and I have so much stuff saved onto it! :(          

Anyway, please reply with a sollution, or even if you've had these before, Thanks guys! :)
