What makes Avast Service use a lot of CPU?
Avast uses more resources than it initially reports. This is because there are several different processes running inside the antivirus software. These include the main process, the background updater, the system updater, the web browser helper object, and the anti-malware agent. All of these processes use up memory and CPU cycles.
The problem lies in how Avast handles the information it receives about itself. When you start the program, it asks whether you want to enable automatic updating. If you say yes, it starts downloading updates and installing them automatically. However, it does not tell you what it is doing behind the scenes. You cannot see the progress of the update installation, nor do you know how much space it takes up on disk.
