Why do you have to remove Gameover Zeus promptly?

As a matter of fact, this Trojan is aggressive and dangerous. According to Brian Krebs, GOZ “has since October 2011 been controlled and maintained by a core group of hackers from Russia and Ukraine. Those individuals are believed to have used the botnet in high-dollar corporate account takeovers that frequently were punctuated by massive distributed-denial-of-service (DDoS) attacks intended to distract victims from immediately noticing the thefts. According to the Justice Department, Gameover has been implicated in the theft of more than $100 million in account takeovers.”  This variant of Trojan.Zbot uses a tiered, decentralized system of intermediary proxies and strong encryption to hide the location of servers that the botnet masters use to control the crime machine. Hackers also use it to distribute CryptoLocker to separate you from your hard-earned bitcoins. Thousands of innocent computer users become the victims of this threat. Once their PCs get infected by GOZ, the Trojan can intercept their online session using a technique commonly known as man-in-the-browser (MITB) when they visit their backing websites. It can bypass two factor authentication and display fraudulent banking security messages to the users to obtain information for transaction authorization. Once users type their confidential information, the attackers will get it and modify the users’ banking transactions and steal their money.
