. On average, about one to two updates a week, although things did pick up into the holiday season last year.
The goal of the RSS feed is to provide information which is accurate, concise and relevant to ESET's customers, such as announcements of new releases, updates, holiday staffing hours for support and so forth. That said, it is not something that gets a lot of feedback on, so whether ESET is hitting the mark there is somewhat subjective.

can also be subscribed to via RSS and features daily commentary and analysis. Although malware is one of the most frequently covered topics, a wide variety of topics regularly come up, including backup strategies, choosing strong passwords, data breaches social networking safety, testing and so forth. Typically is about one post a day, but that tends to vary depending upon conference schedules and the like.
