One of the questions we get asked all the time is “What are Viruses, Spyware & Malware” often followed by “Why do they need to be removed?”
Simply put Viruses, Spyware and Malware are programs which are designed to install themselves on a computer (usually without your knowledge) and then run to perform undesirable operations, this process is sometimes refered to as “Infection”. Most of these infections can spread (propagate) to other computers either through a network, users copying files bewteen personal systems and/or the forwarding of emails, this makes it even more important to address the issue ASAP.
Probably the biggest risk of modern viruses are from so called “Trojan/Trojan Horse or Backdoor” infections. These are capable of stealing personal information from your system such as your usernames and passwords and sending them off to criminals. This could end up with your email account being comprimised or bank account and credit/debit cards being used without your permission to a worst case scenario of your bank account being emptied!
