Hello friends, is there any method to avoid Win-Trojan/Zbot.62976.Q from entering the system, that is installed with Windows Vista operating system? I am using AVG antivirus, that alerts me about this infection everytime I use the internet. I can successfully delete the infection, if it enters the system, but it enters all the time I use the internet. I cant understand why this is happening. So, I need some measures to keep my system safe from infections. Please help with suitable remedies.
