Which installation method is most likely to put your computer at risk of downloading a virus?

The Internet installation method is often the most likely to expose your computer to the risk of downloading a virus because it involves downloading software from the web, where the source may not always be trustworthy. When you download files from the Internet, particularly from unknown or unsecured websites, there is a heightened chance of inadvertently obtaining malware disguised as legitimate software. Cybercriminals commonly use the Internet as a vector to distribute malicious programs, making it essential to ensure that downloads come from reputable sources or official websites.

In contrast, a CD or DVD installation typically involves media that is obtained physically and can be verified easier. Local installation implies that the software is already on the machine or a local network, minimizing exposure to external threats. Peer-to-Peer installation often depends on shared files from other users, which can carry some risk, but authenticity checks are generally more feasible within a controlled environment. Thus, while all methods carry some risk, Internet installations present a greater vulnerability to malware attacks.
