ESET is a Slovakian software company that specialises in cybersecurity that was founded in 1992. Its name comes from the Slovakian translation of Isis, the Egyptian goddess of health, marriage and love. They provide products and services both for companies and for individuals.

One example of the latter is the Online Scanner. This is a one-time use tool which does a free full scan of your computer to remove all viruses and threats. However, this is only a one-time process. If you wish to have more scans or better still, have a live monitoring so that any time your PC encounters something potentially risky, or has a chance of doing so, it alerts you, you have to pay for ESET HOME Security Premium for £51.99 for one device per year(if you add more devices, it increases by £4 per additional device). 

ESET the company has great reviews on Trustpilot with praise for the security of their devices and the fact that the software doesn’t slow them down. Additionally, the customer service team is praised for being helpful, friendly, and quick to resolve any issues. Only recurring issue is that the renewal process is a bit difficult, but the customer service is effective at solving the problem.
