Simple Advice for Zeus GameOver Virus, CryptoLocker / Malwear and other Virus
You may of seen reports recently in the media about a computer virus known as GameOver Zeus. Thought there are other varieties of malicious software with similar effects. Below is a short explanation of how your computer gets it, what it does and how best to protect your computer.
How do I get it?
The virus mainly spreads by people opening files attached to emails. Currently the emails usually appear to be remittance advice or invoices, the attachments appear as zip files.
What does it do?
Once the attachment is opened, it downloads the actual virus which has two purposes :-
1) It intercepts traffic going to banking websites, recovering passwords etc.
2) It encrypts all the files on your computer, and network drives attached to your computer and renders them permanently unreadable. Most variants then display a “ransom” demand
Because of 2) the virus has the potential to completely destroy all the data on your computer and any folders it is attached to, even across a network. For some variations of this Malware there is a tool to recover your files. However, most variants encrypt the files, and mean the only way to recover your data, pictures documents is to restore from a backup. You do have a back up don’t you?
How not to get it!
If there is the slightest doubt about the authenticity of an email, do not open any attachments with it. Delete the email and create a new email to the supposed sender, using an address you already have for them, to confirm the email is authentic. Do Not simply click reply.
Help! I think I might of opened a dodgy email attachment either at work or at Home.
