Anti-malware is a vital tool to protect your systems no matter what the operating system and device type. There are many free options. We previously discussed why it was important to keep anti-malware updated.
Anti-malware needs to be layered to be effective. What do we mean by this?
When you have anti-malware on your system, it is a database of signatures of bad things that are out there in the wild. When you download something it looks at the signature at the file to see if it matches. The problem with this is that there is always a lag between when the bad things are released and when it becomes recognized and added to the signatures. So what do we do?
It is vital to have real time protection on all your systems to catch things. It is also important for cyber hygiene to go back and allow your anti-malware to periodically do a full system scan so that it can see if anything made it through before it was recognized by the system. Full scans do slow down computers so it is best to schedule it at a time people are not trying to work.
