It wasn’t that long ago that anti-virus software was the epitome of computer security, especially if you were a Windows user. However, ransomware and crypto malware attacks are rising at a terrifying rate and show no signs of stopping. Unfortunately, traditional anti-virus software alone is not effective in dealing with these types of attacks
Although experts still recommend using anti-virus software to protect your computer, this is now only the first part of a “layered approach” to keeping your PC and personal information safe.
The second part of the “layered approach” is to ensure your computer’s other software (especially the operating system) is up-to-date. Remember the WannaCry ransomware attack which struck the NHS’ (amongst other organisations) Windows machines in May? Microsoft had already provided a software update about two months before the attack that protected users running operating systems like Windows 7 or Windows Vista from WannaCry. However, PCs that hadn’t been updated or that were Windows XP were left vulnerable. Microsoft says users who were running Windows 10 weren’t affected by the attack.
Don’t forget to keep your anti-virus software, like Windows Defender, updated too. The software can't fight a threat it doesn't yet know about, and that information is found in regular updates.
The third layer is to recognise that phishing attacks are the most common way for attackers to get into your system. Phishing attempts happen when you receive an email with a malicious link in it, or are asked to enter your username and password on a website that impersonates your bank’s website, for example. So, try to be smart about what email service you use. Google and Microsoft are good choices, because, as they have effective inbuilt controls and security, they help prevent phishing in their Gmail and Outlook.com email services.
DO BACK UP YOUR DATA REGULARLY, because should your computer become infected by ransomware, you can wipe your computer, install the operating system from scratch, and then restore it from the backed-up version. OK, so it can be a pain to do, however it’s better than losing everything. Don’t forget to unplug your back up drive from the computer once the backup is done, otherwise it too will become infected.
Finally, as I have mentioned many times before, vigilance and common sense are crucial factors in helping prevent malware and ransomware attacks:
Never follow links from e-mails. Instead open a new tab or window and enter the URL of your bank or other destination manually.
Enter your username and password only over a secure connection. Look for the “https” prefix before the site URL - if there is no “s,” beware.
