Why keeping your anti-virus up to date is important

New viruses constantly emerge out of nowhere. Malicious hackers have a harder time getting to your computer than they used to, but we still need to protect our computers with anti-virus software. Some viruses have been around for a while, but they have avoided detection until recently. Viruses can steal your personal information, ruin your productivity at home or at work, and make it difficult for children to use the computer for educational purposes.

Hackers often send viruses called key loggers into your system to try to steal your information. When you type in your social security number, bank account number, pin numbers, and credit card numbers online, they are hidden from view to protect you. Some hackers send viruses that can remove these safe barriers and steal your information. With that information they can steal your identity, remove funds from your bank account, max out your credit cards, and more. Safety online should still be the number one priority, so you must keep your anti-virus software up to date to catch these malicious acts before they catch you.

The definitions within the anti-virus program are what keep your computer secure. Let’s say your definitions are three months old. Any new viruses created in the last three months can then freely attack your computer since your software doesn’t recognize them as threats. You must have the latest definitions since they are loaded with the correct detection abilities to remove threats before they cause damage. The right software blocks threats before they can latch on to your computer and harm your systems. We will keep your computer healthy and safe with new anti-virus definitions.

Installing new updates can be a confusing and time-consuming process if you don’t know exactly what to do. You can’t afford to take chances with something so vital to the safety of your computer. We have the tools and abilities to update your anti-virus software with all of the latest technologies. Your computer needs the newest virus definitions to block and remove the threats that have just emerged lately.

Malware Attacks – Is Your Business Protected?

Malware Attacks – Is Your Business Protected? 150 150 Greenlight Managed IT Support Services | Sydney | Melbourne

Earlier this month antivirus companies discovered a new and exciting, quite nasty piece of malware on the Internet. Short for malicious software, malware is often used to gather access to sensitive information, or to infiltrate and disrupt computers and networks.

Those pesky cyber criminals have been hard at work, creating a nasty program that will essentially lock all of your files with an uncrackable password. But don’t worry, they will return to save the day with the password and a hefty price tag!

The malware is generally deployed to people via infected websites and via phishing emails. They know how important data is to your business, and that’s why they are targeting small and large companies.

Think of it like this:

  1. A virus infects your computer, generating a public key.
  2. It then scours your computer and network, gathering all the data it can find.
  3. The virus contacts the keylogger’s server, and requests a private key.
  4. This private key is simply a super password that cannot be cracked (unless of course you are the NSA).
  5. Now they have something you need. Something that you would pay to get back.

It’s like having two locks on your data, and a criminal organisation wants you to pay for their key to access it.

 

You may have read about some instances of this kind of cyber fraud that have been leaked to the public. One in particular that shocked us the most was a medical practice in Miami, Gold Coast. The malware virus that infected their systems forced them to roll back 1 year of patient records – the virus had even encrypted all of their backups. Scary stuff.

Here are a few tips and tricks I recommend to companies who want to avoid this nasty:

  • Conduct regular Offsite backups
  • Conduct user training on phishing emails
  • Carefully read emails
  • Check all links in emails before you click them
  • Do not open dodgy or questionable attachments
