Did you click on an email link or download an attachment?

If you went to a website and entered any personal details or a credit card number you may also have fallen victim to identity theft. If you are concerned about your credit card call your bank for more advice.
Do you have up to date security software?
Anti-virus software is one important way to secure your computer (we have more tips below).
If you don’t have anti-virus software installed on your computer or just want to double check the security of your machine you can use one of the following free web based security scanning tools.
We particularly recommend using the ESET Online Scanner if you visited any sites linked to from the Xtra spam emails.
You should also download and run Malwarebytes Anti-Malware Free and consider their paid version. This tool will check your system for malicious software.
Each tool has its strengths but remember that these are only effective at the time you run them – you need security software installed that will offer real time protection, checking files you download and links you click on.
Downloading free or buying reputable software that runs regular scans (these can be timed to run when you don’t need to use the computer to work more quickly) and is frequently updated to counter ‘zero day’ malware is one of the NetBasics steps to improved computer security.
Online scanning tools
Scan your PC in one simple click without having to register any contact information and using the same heuristic detection algorithms available from ESET’s Threat Lab.
A free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software (expires after 10 days).
Download the free Norton Security Scan which will conduct automatic weekly security scans.
