How to Secure Your Business Against Computer Viruses
Bank accounts, client information, protected business processes… all are right there in front of you and can be accessed with the touch of a button. Every business has a least one computer with all the crucial information contained within. Truthfully, a good business can’t run without a computer these days.
So why is it that, despite the obvious threats of hackers and the like that loom out in cyberspace, many business computers (and even personal computers) are not being properly protected? Even if you think you’re taking adequate precautions to protect yourself and your business, chances are, you’re missing one of the crucial elements that will leave a gaping hole in your system, making it fully accessible.
To properly and effectively protect your computer, be sure to follow these steps:
1. It is absolutely critical that your computer have an anti-virus scan program, such as Norton, Mcafee, or my personal favorite used on all my home and office machines Panda Internet Security 2007. Most new computers come with one installed, but only with about a year subscription to their services. Once that year runs out, you no longer have access to the updates required for continued protection, so always keep your subscription up to date. The yearly cost far outweighs the loss you could have if a virus attacked.
2. It is also imperative that you regularly update your anti-virus programs virus definitions. Typically you can set the program up to where it updates the definitions automatically, without even bothering you. This is efficient if your system is connected to the Internet 24/7. If not, be sure that the definitions are updated when you do connect. Without current virus definitions, your system is not protected from the latest bugs.
3. Make sure that your operating system, like Windows, is regularly updated as well. Again, you can set the system up to where it updates automatically, but even then it will occasionally ask you about certain updates. Typically these updates contain software security patches. These patches do exactly that, they patch up holes in the system that may give access to hackers and viruses.
4. Run virus scan often. At the very least, run it weekly, but more often will protect you better. Also, be sure to back up the documents, projects and information you have saved to your hard drive on a regular basis. If you’re using a server, have each computer user back-up their information to the server weekly. If not, I recommend backing-up to a flash drive or CD-R. Save information that you could not replace if the system were to crash.
If you do end up with a computer virus even after taking all the precautions possible (and it can happen at some point), there are steps to take to get rid of the problem. First and foremost, if the infected computer is connected to a network, immediately disconnect and isolate that computer. Some viruses are able to quickly spread to other computers on the network. Train your employees to take proper action when a problem surfaces.
Next, find the removal tool for that particular virus. Your anti-virus scan program can warn you that the virus exists and say that it is deleted, but 9 times out of 10, it’s not completely gone. You will typically need to use the removal tool, most of which can be found by doing an online search with “[virus name] removal.”
Once the virus is removed, be sure to do another virus scan, just to make sure. If the virus crashed your operating system, format and reinstall. This is where the backup that you’ve been running comes in handy. You can always reinstall programs, but cannot replace the information on those programs, such as the client bills for the last three years.
And finally, once everything is reinstalled, run virus scan again, just in case. You can never be too careful when it comes to computer viruses… ever.
