In terms of basic protection, Avast has been shown to be one of the best antivirus programs out there, scoring a 5.5 out of 6 in in AV Test’s protection test. The latest free antivirus suite from Avast! is an impressive package. Aside from the usual virus and malware protection — including anti-rootkit and anti-spyware capabilities — the software comes with a slew of customizable options you can toggle at installation, including protection for your Android devices through Avast mobile Security & Antivirus. The 2017 version of Avast goes the extra mile when it comes to making sure you feel safe using the program; at installation, there is a very clear breakdown of exactly how Avast! uses your private information.

Avast gets out in front of potential malware attacks by initiating scans before an unknown file opens, and will prevent it from doing so should it cause any red flags. The software is good at protecting your PC while online, blocking malicious URLs and stopping auto-downloads from occurring. The 2017 version watches the behavior of specific apps to see they are doing anything suspicious, as well. 

Of course as a free program, you’ll be missing out on some features exclusive to the paid package, including auto-scans and auto-updates. Those wanting such upgrades will need to opt for a subscription plan, which ranges from $10 to $180 per month. Still, sticking with the free version will keep you well-protected.
