A common method of infection of a Windows computer is for a 'dropper' program to be run on a computer that then downloads a 'payload' file which actually does the malicious work. The initial dropper file is usually programmed to delete itself to avoid detection. The payload file would then remain active on the computer and is programmed to carry out certain tasks (e.g., pop-up adverts, warnings that you are infected and need to buy protection (scareware), encrypt personal files and demand a ransom for unlocking them (ransomware), contacting a command and control server to await 'orders' for exactly what to do, etc.) In this more common scenario, because the payload file has to remain active so Sophos AV can easily acquire a sample of the file and see if prevention from infection is already covered (e.g., in Sopho's existing library of file detection, or through our intelligent heuristic detection methods). If required an update can be published and Sophos users who enable Sophos Live Protection are immediately protected - those who disable Live Protection with receive the update (along with Live Protection users)

Is your PC still being infected by viruses and malware regardless of all of the latest anti-virus and anti-malware protection that you installed on your system?

As bold as it sounds, it is intended to make the internet safer. The reason he states is that millions of PCs worldwide still do not have basic antivirus protection, and thus are susceptible to infection as a result of increase software costs. He states that antivirus software companies will still make profits and their user base will increase by issuing the most basic form of antivirus software (Vamosi, 2004). The responsibility will then be placed on the end user. Ultimately, this distribution of software would help in decreasing the virus threat.
