Avast has over 30 years of experience hunting down malware like rootkits – no matter how well hidden.
Rootkits trying to access your system will find it impossible to infiltrate Avast’s defenses.
New rootkits are created every day. So we update our protection every few minutes to ensure you stay safe from the very latest threats.
No matter what kind of attack threatens your PC or your data, Avast is equipped to deal with them all.
After rigorously testing 18 of the world's most popular antiviruses, independent test lab AV-Comparatives has awarded Product of the Year 2018 to Avast Free Antivirus.
We’ve packed the world’s largest threat-detection network and machine-learning malware protection into a single, lightweight malware scan and removal tool that won’t slow down your PC. And did we mention, it’s 100% free?
When so many pros trust and recommend us, we must be doing something right in the fight against rootkits.
But don’t just take our word for it.
The UI for your software - amazing. Great work over the years. Can't say enough good things!
Thank you, Avast, for the excellent work you do. I run your antivirus software on both my Mac OS X and my Windows machines. You have the best products on the market, period.
I’ve been using Avast for over a year and have found it one of the best free software protection devices on market.
Rootkits don’t care what device you use, which means Macs and Androids aren’t safe either – unless they enjoy Avast’s powerful protection.
For your Mac, we have free Avast Security for Mac, which hunts down and destroys rootkits, as well as any other threat that has taken over your machine. We even take your security one step further by constantly scanning your wireless network for any unwelcome visitors.
For your favorite Android devices, we have another free solution: Avast Mobile Security for Android. Enjoy your phone fearlessly knowing it has the world’s most powerful antivirus protecting it, and take it out of the house without a care thanks to our battery-saving and anti-theft tools.
Say “goodbye forever” to rootkits and other threats with Avast Free Antivirus — at the low, low price of free.
