How to Protect Against Malicious Software

What is malicious software?
Malicious software (malware) is any software that gives partial to full control of your computer to do whatever the malware creator wants.  Malware can be a virus, worm, trojan, adware, spyware, root kit, etc.  The damage done can vary from something slight as changing the author’s name on a document to full control of your machine without your ability to easily find out.  Most malware requires the user to initiate its operation. Some vectors of attack include attachments in e-mails, browsing a malicious website that installs software after the user clicks on a pop-up, and from vulnerabilities in the operating system or programs.

Malware is not limited to one operating system.

Malware types can be categorized as follows:

  • viruses
  • worms
  • Trojans
  • backdoors

These malware seek to infect and spread themselves to create more havoc.

Adware and spyware seek to embed themselves to watch what the user does and act upon that data.

Root kits seek to give full access of your machine to the attacker to do what they want.

What can I do?

  • First and foremost, make sure the operating system and any program you use are up to date with patches/updates, as mentioned here.
  • Always be wary of any strange e-mails, especially ones with attachments.  If you are suspicious about an e-mail, you can always contact the sender and ask if their message was legitimate.
  • When browsing the internet, always watch what you click and install.  Do not simply click OK to dismiss pop-up windows.  Also, make sure to read through the End User License Agreement (EULA) before installing; some malware actually list themselves in the EULA so that you legally agree to install them!
  • Use a web browser other than Internet Explorer. IE has some inherent vulnerabilities that allow malware to be installed by just browsing a malicious website.
  • Install anti-virus software, and scan and update regularly.  In most cases, It can remove and prevent viruses, worms, trojans, and (depending on the software) some spyware.
  • Install anti-spyware/anti-adware, and scan and update regularly. It will remove and (depending on the software) prevent future adware and spyware.
  • Follow the rest of the security recommendations to protect against root kits and other more severe attacks.

Anti-Malware Software
SEASnet does not have any anti-spyware/anti-adware software.  However, there are many anti-spyware/anti-adware programs available on the internet. Here is a list of a few of them:

Root kits were primarily the domain of Unix based operating systems; however, Windows root kits are starting to show up.  Here are a few root kit tools:

*Some websites require Internet Explorer to work properly.  If the alternate web browsers do not work for these websites, then fall back to using IE.
