Computer security is a growing concern for us here at the Chemistry Computer Facilities. We want your access to the Internet to be safe, secure, and productive. Viruses, spyware, and other threats known as malware are a major problem for everyone. In many cases, we have to rebuild your machine if a it becomes compromised by a malware threat. This may require significant downtime, especially if the Computer Facility has multiple machines to work on simultaneously. It's best to keep your machine updated with the latest operating system patches as often as possible to prevent malware attacks. Performing updates at least once a week is often enough to prevent security intrusions. The first time you run this kind of activity on a machine that hasn't been updated in a while, it may take a long time for the updates to complete, but the effort will pay great dividends in the long run. Keep in mind that new viruses are introduced each week and consequently new virus updates and software patches are also introduced soon after to counteract them.
We would like everyone in the department to keep all of their computers updated using the suggestions below.
