What is Chrome.exe virus?

Chrome.exe virus is a generic name that refers to the Poweliks trojan. Cyber criminals disguise this malware as a "Chrome.exe (32 bit)" (or, rarely, "dllhost.exe" or "cmmon32.exe") process in Task Manager (why it is called Chrome.exe virus).

Developers use Poweliks to generate fraudulent advertising revenue - this malware is designed to generate intrusive online advertisements (coupons, banners, pop-ups, etc.) In addition, Poweliks uses virtually all computer resources. The system thus becomes unusable (applications continually crash due to lack of resources, screen freezes, and so on).
