Recently I get infected by a malware called Zombie Invasion. I tried to remove it from control panel but it doesn't work. I have used an antivirus (Avast antivirus) who seems to detect some malware, but after run the clean the malware still stays.
Main problem is my browsers added some annoying ads, and also become very slow after a time.
I googled for getting a solution but I don't trust the programs these websites tells me to install to remove Zombie invasion.
Any help? Thank you.
