I work at an insurance company in the U.S. My colleague got a notification on his machine of a possible virus (through the virus scanner that is installed by default on all machines). He called up the tech department, and they simply told him not to worry about it and continue his work as normal, as they will look at it at the end of the day after he is out of work. I was pretty surprised by this, as I would assume that a virus detection could possibly be any form of malicious code that could potentially infect the network, and compromise my colleague's data. We work as developer's on the company's database. So a virus could potentially be lead to stolen client's data from the database, or even closed source code on the local machine.
Am I missing something here? Do big companies monitor the network in a way that they feel secure about a potential virus on one user's machine.
