Computer Death Virus

This is the second virus I've gotten on my new(ish) Dell XPS laptop purchased (by work) in October. For the last 5 years or so, I have been a strong Mac advocate, but recently I started thinking Windows 7 was... okay. I'm really not sure exactly how I'm getting these little guys, porn/torrents/working on my associates degree in general studies from University of Pheonix Online, I guess any of these things can be giving me a virus. The first time I fixed it no problem, with a free scanner program called Malwarebytes. But this lil' guy is worse because it detects when you run a anti-malware or anti-virus scan and makes it crash. The virus itself appears as a windows security window, but right away, you can tell its not legit because it looks kinda shady! But there is a new program called rKill I'm running right now that blocks the malware from blocking your anti-malware... Hopefully this works... 30 minutes in and it's already detected 24 infected objects!! So, stay safe and wear a condom if you are computing with a PC, but if you have a Mac compute freely and condomless!
