I am running on windows 8 64 bit installed onto a current 27" iMac. Somehow I have obtained a malicious file that has hidden itself and rooted it's way into the inner workings of the OS.Whenever I go to use the "Omnibar" on google chrome, my search gets redirected to a fake yahoo search. First of all, I would like to ask if I can provide the link to the site that I get redirected to, as it violates the terms and conditions of EMC to intentionally provide malicious code or software. (It would not be intentional... just dont visit the link if I am allowed to post it which I probably won't be. It may help. Anyways, I have installed the free version of Malwarebytes and Anvisoft Smart Defender. They tried to quarantine minecraft but I whitelisted it and it only. I allowed them to quarantine any other files. They both found a file called "Trojan.agent" in the my JVM and JDK. I have uninstalled both and reinstalled only JVM (which is actually still installing at the moment).I request help from anyone who can give it to me. I would not like to completely delete windows 8 off my drive, but it is a last minute possibility.
