First, sorry if I'm a little slow with some of this as I'm moderate with my computer knowledge.
Earlier today I had 517 gb of memory available in the C drive. I restarted my computer earlier today and once it restarted I saw I was down to 1.84 gb. I ran crap cleaner already and did a quick scan with malwarebytes but no answers.
I also noticed a new file listed named c:\END. When you open this with notepad it says "conduitok"
There also seems to be ads and a new toolbar listed in IE. Any ideas how to find out what the heck is going on here?
