FAQs

How can I get rid of adware?

There’s no better way to clear your system of adware than a powerful antivirus like Avast. Not only will it scan your device for adware and remove it, but it will also block it in the future.

 

Is adware a virus?

Technically, no. A virus self-propagates and spreads, while adware just bombards you with advertisements. Instead, we’d classify adware as “malware” — which is an umbrella term that encompasses all kinds of threats, including adware and viruses.

Does adware slow down my computer?

Absolutely! Adware bogs down your computer by forcing it to use it’s processing power and RAM on loading and displaying ads, rather than on the processes and programs you actually care about. If it gets bad enough, adware could slow your computer down to a crawl. Fortunately, we can show you all kinds of ways to speed up your PC.

System requirements

We’re not demanding. All you need is a PC with Windows 10, 8.1, 8 or 7*, 1 GB RAM 
and 2 GB of hard disk space. And that’s it.

* Both the 32- and 64-bit versions, excluding Starter and RT editions.
