Small business owners might ask, “do we need an antivirus program?” The answer to that question is a most emphatic yes. But don’t worry, it’s not difficult to choose the right antivirus for your business needs. In fact, there is a range of products that are low cost or free, and very simple to use. It really doesn’t have to be complicated.

If you’re starting a business but you’ve used antivirus software on your home desktop computer, you probably already know most of what you need to know. Only companies running large Web-facing networks with multiple servers need to worry about more complicated antivirus solutions. The rest of us can turn to tried and true answers.

For example, many new desktop computers come with an antivirus like McAfee already installed. If you only have one or two employees, chances are that the solution is already installed and waiting to be used. McAfee has options to set the strength of protection, the time for scheduled scans, and additional features including a personal firewall. McAfee sells yearly subscriptions that entitle the user to all updates and bug fixes.

Other popular antivirus programs include AVG, Sophos, Symantec, Norton, Trend Micro, and Bit Defender. Most have a free trial period so you can see which works best for you. Just be sure to choose one, so that you and your office systems remain protected from viruses and trojan horses that can literally shut your business down.
