can the virus get a virus ?

To my knowledge, the Access Virus is programmed in assembly language.

Plus the operating system of the Virus is read-only until you put it into "update mode", and even then I believe there's a buffer which checks the data in memory to make sure it's legit before finally flashing the ROM with the new OS.

Avast is superb for your Windows PC. I've used it for the past 7 years or so and it's saved my ass a number of times, every time. Whereas others (such as AVG) haven't.
