Avast antivirus programs always did the trick for me. There are lots of variations to pick from, and I like it when I'm given a choice. Probably because I can select Avast Free Antivirus, one of the most popular antivirus protection solutions in the world.
When you launch the installer, you can select the components you want to install and the interface language. There is a registration procedure, but it's completely free and used for statistics. The interface is pretty and does not confuse, which means it does a great job of letting casual users like me master the program. The panels and menus look like something out of Windows or Android OS. There are three main security screens giving you full control over all security functions: web, file and system. You can change the settings with a universal control tool, which gets you rid of the tedious process of adjustment and trying to set the antivirus right.
The antivirus scanner in Avast supports a great number of scenarios for a thorough check in any system. One especially useful function is the possible check at system start to get rid of some of the worst and well-rooted hazards. Some of the secondary protection functions are distributed over subsystems, which makes the work less complex.
Avast Free Antivirus also utilizes cloud technologies for effective checking of suspicious files, data transactions and updates, being able to quickly introduce new methods of scanning, prevention and malware identification once implemented. DeepScreen technology deserves a mention: it is used to handle unknown and unidentified files and provide protection for applications or the code itself. Those applications that didn't pass DeepScreen or have a low status in the FileRep section (which evaluates file safety and stability), are blocked by the special Hardened mode. Safe programs can be run without restriction.
Avast Free Antivirus also does a good job of keeping suspicious Internet addresses and incoming files from harming your computer, blocking them and sending warning messages. The mail protection system monitors and protects your email data exchange. The Online Security extension provides online assessment of reputation of specific sites, and the web security screen may be used to include preventing measures against accessing hazardous resources. There is also an option to use the Do-Not-Track mode and surf the net with more anonymity. A user can also run the Browser Cleanup to get rid of annoying and not needed panels and add-ins.
The Software Update components check most popular programs available on the user's computer for vulnerabilities caused by obsolete versions and offer an opportunity to automatically download and install updates. Avast Free Antivirus can be used on several connected devices for remote management. For this, the technology called AccessAnyware was introduced in 2014. A user can remotely access the computers that have AccessAnyware installed. Should this not prevent an infection spreading across an operating system, there is an option to use Avast Free Antivirus with Rescue Disk, creating a bootable Flash drive to run and heal the already-damaged system.
Avast Free Antivirus is simple, but functions extremely well and offers a lot more than any other free alternatives, even more than some paid programs. This makes Avast Free Antivirus one of the most well-respected antivirus solutions today. At least in my book.
