You may have recently had a malware infection on your computer and wondered how it even happened. Maybe you had an infection in the past and only have a vague notion as to how it occurred. If you’ve ever wondered how to prevent a malware infiltration of your system or gain a better understanding of how it works, this is the place to learn.
How Does Malware Get on a Computer?
First and foremost, you need to understand how malware even got on your computer or into your network. There are various reasons as to how you got that infection, but the leading causes are:
- Downloading From Unreliable Sources: Have you ever received an email with a download link that seemed a little fishy but didn’t set off any alarms? If you click on links without first checking the full destination URL and the full email address of the sender, you could be downloading malware that will spread like wildfire.
- Phishing Emails: It doesn’t have to be a software download; merely clicking and following a suspicious link could lead you straight into a trap. Having the right managed and monitored endpoint security in combination with managed phishing filtering in place is the ideal security solution to keeping phishing emails from harming your business.
- Pop-ups: Ideally, you will have an ad-blocker in place to prevent accidental clicks, but if not, then clicking on an ad or pop-up could lead to trouble. Always double-check link destinations before clicking, or, to avoid problems altogether, try not to click anything unless it’s explicitly safe to follow (author links out to another site in the text, citation links, and other similar cases).
These are the most common occurrences in a work environment that could cause problems with malware. Always have your eyes peeled for trouble and have the latest security measures in place to keep your personal information intact and give you a safe browsing experience.
How Does Malware Spread in a Network?
Let’s say you accidentally clicked a link you shouldn’t have and you now have malware. It’s not a big deal right? IT can come in and do their magic, sweep up the issue, and everything is back to normal, right? Wrong. First, you need to know the signs of malware on your computer so you can let your resident experts know as soon as possible. The significant signs of infection are:
- Increased pop-ups when online and using your desktop: Links may open automatically, random pop-ups appear even when you aren’t online, and other strange behavior is a clear indication of malware.
- Program Issues: If programs are opening and closing at random or other issues occurring around your applications, something else is at work on your computer.
- Strange Emails: If you are receiving a sudden influx of spam emails or emails from unfamiliar, unknown senders, there may be malicious software on your computer.
- File Lockout: Files that you’ve had access to before or that are public are suddenly locked. This either means that administrative access has changed or you have an unwanted guest.
If you see any of these signs, then you have a problem on your hands. Hackers use advanced tools that are specially designed to spread malware across your network. Once they have a way in, be it a stray link, email attachment, or otherwise, they probe through your system looking for data to steal or exploit. Malware typically slows down your computer and damages your system. The stronger malware can’t be detected by conventional virus detection and requires specialized services.
What Should I Do if I Think I Am Infected with Malware?
Each case is different, but here are two things you should do immediately:
- Let your IT department know immediately – time is of the essence if you’ve been infected, so don’t wait or think the problem will go away. It won’t; it will get worse. Call you IT department ASAP.
