If you don’t have any antivirus (AV) software installed, it would be a good idea to get it now. We don't generally support free antivirus software - you get what you pay for - but there are some packages around if you search on the big names for free versions, and these are usually for personal use only. If your use is commercial (including charities), and if you’d prefer full technical support, we recommend commercial paid-for versions. We can install, support and manage workstations and servers from as little as £25+VAT per year. Contact us for more information.
If you already have security software installed on your system, you should ensure that it is kept up to date; sometimes the automatic updater is not enough, and you should regularly check and force updates - both to the security software and your operating system.
