Viruses and other forms of malware can cause plenty of annoying problems when they find their way onto a home computer. When they appear on a business network, however, it can spell disaster.
As computing systems grow more sophisticated, so does malware, and many types can quickly spread throughout your network and prevent or slow down your employees' ability to work. It can also compromise sensitive files. Some forms, the dreaded ransomware, will completely shut down computers in an attempt to extort money.
Although an IT professional would normally be able to clean your network and fix the problem, it still means some downtime and potentially lost work and files. As always, prevention is best. Here are some of the more common ways malware gets onto business computer systems, so you can try and avoid them.
By far the most common way malware spreads is through email. These messages sometimes have intriguing or enticing subject lines and they might even be sent from a legitimate contact whose email account has been hacked. They either contain a harmful attachment or have a link to a malicious website.
Email providers have become increasingly adept at detecting and filtering harmful messages, but some still get through. Make sure your employees are vigilant.
Staff sometimes download files to their computers, whether they're allowed to or not. Files downloaded from the internet are frequently infected, but good antivirus software should detect them. You can also set up operating systems to prevent new software being installed.
A major tactic of malware creators is setting up websites that look legitimate, but exist to infect computers. Many of these can be blocked with various software solutions web browsers, and you should provide training on how to spot a fake site.
USB pen drives
People who sometimes work from home are likely to carry files to and from the office on a pen drive. If their home computer is infected, this can spread to the USB stick and onto the company network. Limit the number of staff who do this, and ensure they're all running reliable antivirus software at home.
Operating systems and other office programs need regular updates to stay current. While this helps protect against security threats, getting the updates from unreliable sources opens up the possibility of malware infection. It's best to leave updates to an IT professional or a single knowledgeable person within your company.
