25/11/2016 -  Some people still do seem to not take backing up their data seriously. Some think that only a "unlikely" disk drive failure is a threat to their data. In most cases, your data is under attack from scam emails more often than you think, and the techniques used are varied and relentless. Often, people are fooled by one of these techniques and their data becomes encrypted. Talk to us about what you can do to minimise the risk of data loss.

04/08/2015 - Windows 10

I am pleased to say that our first Windows 10 upgrade has gone smoothly. It looks great, nobody will be mourning the passing of Windows 8/8.1. In case you are wondering, there was no Windows 9.


03/09/2014 - The "Cloud"

I hope this current scandal, where hundreds of intimate pictures of the likes of Kate Upton, Rihanna, Kim Kardashian and many others have been leaked online, remains a constant reminder of what can go wrong with backups to the “Cloud”. In this case, Apple’s iCloud service has been blamed. We find this program on many computers, even though the vast majority have no idea what it is or does. While most are unlikely to have naked images stored anywhere, this episode does show how personal data backed up to the cloud can be potentially be accessed by anybody, anywhere in the world, (particularly if your name is similar to a well-known celebrity). If activated, iCloud automatically stores photos, email, contacts and other info online, allowing users to sync this data across different devices (for example PC’s, iPhones and iPads) and access it from any internet-connected device using a log-in and password.

Cloud has become a real buzzword hasn’t it? But it really is just a new name for an old technology. After all, Hotmail is a cloud application and it has been around since 1996. Many are quick to embrace this “new” technology but for a while now, I have been discouraging small businesses in particular from using the cloud for backups. 

So the bottom line, do your own data backups, particularly work data. Backup to an external drive, check it regularly, and guard it carefully.   


12/11/2013 - Cryptolocker (Virus) Alert

Please be aware of a ransomware variant (AKA Virus) called Cryptolocker that infects systems and encrypts files.  

At the moment, it is spread via malicious links in junk emails which lead to pages that exploit system vulnerabilities. Possible future variations may get in via a hacked web page, but that’s a problem for another day.  

Affected users are asked to pay a cybercriminal a "fee" in order to unlock their system and have the files decrypted. Payment must be made within 72 or 100 hours, or else the decryption key is destroyed and it becomes virtually impossible to restore files (even for experts).  

The main issue with Cryptolocker is that even if the pest is removed, the files are not restored.

It is extremely important that you have a good backup system in place and are up to date with Windows patches and antivirus software. To avoid infection, do not open email attachments from unknown people, or visit untrusted websites or install dodgy software.  

As always, we at Corella Computers urge everybody to regularly back up their files to an external drive, and to check that the backup data looks OK. At least then if you are caught out with “ransomware”, data loss will be at a minimum. Need a decent backup system? Call us.  


09/04/2013 - "Ukash" Ransomware

We are getting a few calls from people with their computer locked up and disabled by what appears to be a warning from the Australian Federal Police. This scam is commonly known as the "Ukash" virus. This virus also has the ability to access your installed webcam ,so that the bogus AFP notification includes a picture of what is happening in the room, typically a picture of you looking at your computer screen (kinda funny when you see it).  

The real Australian Federal Police issued the following warning on Thursday, January 31 2013.  

Scammers are continuing to use the Australian Federal Police (AFP) logo in an attempt to defraud Australians by asking them to pay sums of money to unlock their personal computers.  

The ‘pop up’ message purports to be from the AFP and informs the computer user that their computer is ‘locked’ and requires the user to pay a fee to ‘unlock’ their system. The appearance of the ‘pop up’ message is due to a virus that is on the personal computer.  

Users affected by this particular scam should not pay any money and should seek support from a repair centre if they need assistance to remove the virus.  

AFP Manager, Cybercrime Operations, Commander Glen McEwen says that members of the public need to educate themselves and be wary of online scams. “Unfortunately members of the public are still being affected by this scam.”  

“The Australian community is reminded that the AFP does not solicit funds and this message is not associated with the AFP in any way. I strongly advise personal computer users to take steps to protect themselves against scams,” Commander McEwen said.

To prevent being caught up in this kind of scam Australians with a personal computer should maintain current anti-virus software that is obtained from a reputable source and is regularly updated, and never click on links contained within spam or unexpected emails. Furthermore, you should always keep your Java and Adobe Flash plug-ins up to date.


08/08/2012 - We were asked for input into this article the Financial Review ran regarding the NBN.



29/03/2012 - NBN Rollout for the Sutherland Shire area.

The residents of Illawong, Alfords Point, Menai, Bangor, Barden Ridge, Woronora, Sutherland, Como and Jannali may be disappointed to learn that these areas are not on the three-year "roll-out" map for NBN installation. In other words, you may have to put up with your existing service until June 2021 when the project is scheduled for completion. If you live in one of the above areas, you may be able to get NBN type speeds now by switching to Bigpond Cable. If you live more than 3 km from the exchange and are fed up with a slow ADSL2 service you should speak to Bigpond (as much as everybody hates them) about making the switch. Don't wait for the NBN. However, if you have never had a cable broadband or pay TV connection to your home, it may well be too late for you.


07/02/2012 - "Windows Service Centre" phone call scam. 

Often, one of our clients will ring us from their mobile phone, while they are engaged in another conversation on their land line from someone claiming to be from "Microsoft" , or "Windows", or something similar. It is amazing (and disappointing) to see how often people think these calls are genuine. Sometimes I get the impression that people don't believe me when I tell them that the caller is attempting  to scam them. Funny how people actually believe that "Microsoft" is on the phone is response to a error message that their computer has sent. These are fake calls and NOT from Microsoft. Microsoft will NEVER call you unless you contact them for help first. Look at this YouTube clip for more info:-

03/12/2010 - Another Scam Alert

During the course of a service call during the week, the client (a solicitor) took a phone call from somebody claining that her computer was sending out virus's. She put the caller onto me. The caller asked if I was the solicitor's husband, I said yes. He repeated his claim that our computers were sending out virus's. Bad mistake. Amongst other things, I called him a liar and a crook, and told him that Australians (he had a strong accent) have been warned about people like him. At this point, the fun ended when the caller hung up,

24/11/2010 - Scam Alert

A repeat of a previous warning;

Warning all as this is happening a lot at the moment. Most people will pick this as a scam, but may waste time trying to be certain that it is a scam. More than one person I know has fallen for this and provided credit card details.


Microsoft Australia has warned customers that scammers were posing as local Microsoft partners offering to purge "infections" from users' computers. These scammers may also claim to represent your internet provider.  

Microsoft's chief security adviser in Australia, Stuart Strathdee, said the scam went under several names, including Support on Click, ITEZY.com and System Recure.

Websites for all of those companies falsely claimed they were Microsoft partners and misused the Microsoft logo.

Customers typically received a call from someone claiming to be working for Microsoft or "your ISP".

The phone number ID may show as originating from Australia, but in reality, the caller is from overseas, usually India.

They will tell you that your computer has been running slowly, or sending out spam emails, and that this is likely due to ‘infections'.

They then tell you that they can help you with this and direct you to a website that then allows them to take remote control of your PC (in doing this they could download spyware to your machine)

The scammer will then spend some time on your system trying to demonstrate where all your ‘problems' are. They may direct you to the Windows Event viewer, highlighting insignificant errors which they claim need to be fixed. They will then try to sell you their repair service and take your credit card details.

Microsoft said customers who received the calls should hang up immediately.

"If you receive an unsolicited call from someone offering assistance to fix your computer then we suggest you hang up, and not respond to any communications from these scammers," the company said.

It said it was continuing "to work with law enforcement and relevant government agencies."
