The virus can do various things, from taking over hard disk space to gaining access to your personal information or draining your CPU. There are a variety of anti-virus software available to guard your devices from these issues. It is important to select an anti-virus that has minimal impact on your system’s performance. Each of our antivirus programs has been tested against this. The results are based on the time it takes each product to complete an operation. Kaspersky Security Cloud Free, for instance had a background impact of only 6% when performing a full scanner, while ESET had an effect of 12%.
Avira is a German-based company. Avira is well-established in our tests and consistently performs above the 90% mark in all three categories: Security, Performance and Usability (False Positives). The interface is user friendly and offers plenty of functionality including a smart firewall and other privacy tools. Avira’s subscriptions are priced on a monthly basis rather than a set 1-3 year period, which makes it much easier to cancel or alter the subscription at any time, without having to worry about 2nd-year renewal price shocks.
A fairly new name that we have tested, Essentware – which was previously known as PCKeeper – uses the Avira engine underneath and generally scores pretty well across the spectrum. Its interface is simple to use and its performance was decent this month, though a few stability issues – mostly due to scan jobs not being able to connect – have lowered the rating. However, the detection was satisfactory, and a perfect run through the certification sets earned it a VB100 award.
