FAQs

How can I get rid of adware?

There's no better way to clear your system of adware than a powerful antivirus. Antivirus software will scan your device for adware, remove it, and help block future infections.

Is adware a virus?

Technically, no. A virus self-propagates and spreads, while adware just bombards you with advertisements. Adware is a type of 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 using up processing power and RAM as it loads and displays countless ads. If it gets bad enough, adware can slow your computer down to a crawl. Junkware — unwanted pre-installed applications — can have a similar effect. Thankfully, there are easy ways to speed up your PC.

System requirements

We’re not demanding. All you need is a PC with  Windows 11, 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.
