The latest phone scams in Australia are from people claiming to work for Microsoft and Logmein. The scammers will say something like:
"We can see from our end that your computer is infected with a virus."
I have even had clients who have received this call whilst their computer was turned off. They cannot see your computer at all, until you actually give them access.
They will then try to get remote access to your machine with your help, thus letting them have complete control of your machine under the guise of fixing it.
In most cases, the computer is worse off after they gain access, so I am assuming that they infect your computer while they have control of it. This is probably going to be a key logger virus that will send them all your passwords for such things as internet banking, email logins and credit card details in the future.
Neither Microsoft nor Logmein EVER call random people for computer help, and they never will, so if you get a phone call from these scammers, just put the phone down and leave it there.
That way, they will pay for a huge phone call if nothing else.
Never tell them anything about your system or software, just say as I do,
"I know this is a scam, and when you get caught I hope you get everything that's coming to you"

Never ignore the Blue Screen Of Death
The blue screen of death or BSOD is a computer technicians term for a hard stop by a windows operating system. It reveals itself when, usually, a peice of hardware dies, or is dying in your computer.
In most cases you will have to hold in the power button for 4 or more seconds to shut down the computer from this error stop.
If you have seen this error with any array of text on it you should get your tecnician to check the computer immediately.
In a lot of cases, this error denotes hard disk errors, and can result in the loss of valuable data.
You will most likely need to have something replaced in the computer, and this error should never be ignored.
If the hard disk is the cause of the problem, the less you try and turn the computer on or use it the better. That way, if it is the hard drive dying the technician will get the most time with it to try and restore your valuable data.
Operating system cleaning- Malware/spyware cleaning
For cleaning viruses and malware/spyware from your Windows XP/Vista/7 three tools need only be used in most cases:
Ccleaner can be downloaded here: http://www.piriform.com/ccleaner.
Thats about it.
You could always run an antivirus scan of your computer as well, but in most cases, it will have done the best job it could do anyway, and will not find anything else.
- Mbam software (Malwarebytes malware removal software can be downloaded here: http://www.malwarebytes.org/products/malwarebytes_free)
- Spybot seek and destroy (spybot removal software can be downloaded here: http://www.safer-networking.org/en/index.html)
Ccleaner can be downloaded here: http://www.piriform.com/ccleaner.

Computer tower cleaning- Physical dust cleaning
Cleaning a computer tower is quite a simple thing to do. You will need:
Undo the two screws holding the side of the computer furthest away from any rear plugs. These will be either phillips head screws or thumb screws.
Then, you will notice the motherboard and stuff inside your computer.
Some may look different to this older model, but the main fan that you can see here is the CPU fan, and is almost always in the same position in the case.
Take the paint brush and gently push any dust away from the blades in the fans for the CPU and the case and power supply fans.
Then use the compressed air can to gently blow the dust bunnies from the computer.
Do not use an "air compressor" as the air blown from these devices can often be moist and too powerful.
After dusting simlpy replace the side of the computer and plug everything back in.
- Phillips Head screw driver
- Air duster can (small can of compressed air)
- Clean paint brush of about 5cm wide
