If you invest in a security product and if you have a large company, it costs you a lot. And if it works perfectly, you have no problem, which means you don't see the product at all. You pay lots of money, but you don't see any results.

There was no market because there were no Mac viruses.

We are seeing less of the big virus outbreaks such as Sasser and Blaster, and so some people believe the situation is getting better, when in fact it is getting worse. The bad boys are getting more professional and doing more targeted attacks.

It all comes down to whether the code ends up being shared or not. We have not seen it out on the Internet yet.

There appears to be three different virus writing gangs turning out new worms at an alarming rate -- as if they would be competing who would build the biggest network of infected machines.

A large company would not want somebody entering their premises with an infected phone because they could easily infect the entire company's phones.

The target is fooled into logging into a fake bank, where they ask for his authorization code. The fake bank logs into the real bank with the one-time password and moves money around. Then it gets back to the customer, says there has been a problem and asks him to give the next code.

But at least you know someone on your premises has an infected phone.

This is the way virus writers can upgrade the infected machines. It's like [Microsoft's] Windows update for viruses.
