By way of comparison and to provide some perspective I will also include some of the numbers for two of the best paid antivirus programs: Kaspersky and ESET NOD32.Summary of findings: Antivir and Avast and both have excellent and comparable detection rates.The free version has a very limited data allowance of 500MB per month (1GB if you register), but that could still offer useful protection for email and basic browsing.Avira System Speedup is a cut-down version of the company's PC maintenance tool.It adds icons to your search engine results, enabling you to spot potential dangers at a glance, and if you click a dangerous link somewhere else it jumps in to warn you of the risks.(If you're completely sure a site is safe you can carry on in a couple of clicks, so the system never gets in your way.) Avira Phantom VPN encrypts your communications to prevent interception, masks your IP address and may help you access websites you couldn't normally reach.
Avira Free Antivirus is the free antivirus software with the really best detection of malware.Avira Free Security Suite 2017 is a capable collection of the program's free security, privacy and optimisation products. Independent testing labs show its engine offers some of the best protection around, comparable with top commercial products from companies like Bitdefender and Kaspersky, and the latest edition ramps up your security even further with enhanced anti-ransomware technology.Avira Browser Safety is a Chrome and Firefox extension which blocks access to known malicious sites.Every day new malware attacks of various descriptions target Windows PCs.Some are scarier than others, but the Wanna Cry ransomware attack that hit huge organisations including the NHS earlier this year left many people more uncomfortable with their PC security than most.
