The virus can do various things, from taking over hard disk space, to gaining access to your private information or draining your CPU. Fortunately, there are numerous anti-virus programs available to help protect your devices from such issues. The most important thing is to select one that is not likely to have an impact on your system’s performance. Every antivirus program we offer is tested against this aspect. The results are based on the time it takes each product to complete an operation. Kaspersky Security Cloud Free, for example had a background impact of only 6% when scanning the entire system, while ESET had an impact of 12%.

Avira is a German company has a great reputation in our tests. It consistently scores above 90% in all three categories: Protection (False positives), Performance (False Positives) and Usability. Its user interface offers a wide range of features as well as a smart “firewall” as well as a variety of privacy tools. Avira subscriptions are priced monthly rather than for a set time period of 1-3 years. This makes it simpler to cancel your subscription or modify it at any time.

A relatively new name that we have tested, Essentware – which was previously known as PCKeeper – uses the Avira engine underneath and generally scores well across the range. Its performance and interface are both simple to use, but some issues with stability such as scan jobs freezing up – have lowered the rating. However, detection was excellent, and a perfect run through the certification sets earned it a VB100 award.
