I made a credit card transaction at my community college's science computer lab. It's an open lab for any students to use.
I didn't think much about it at the time, but then started feeling a little weird about it later on today. I figured in the back of my mind that the university probably updates and protects these computers as well as anyone. I always see those nightly "computers will be shutting down and updating" messages that forces us off the PCs for a while for maintenance. I figured they'd probably be just as safe is not safer than my home PC. But now I'm having some regrets, since I'm not very knowledgeable about computers.
Was my assumption right? How safe are college computers and should I block my credit card to be safe?
Feeling a bit nervous and upset with myself at the moment. I was Christmas gift browsing on the internet and wanted to make a purchase right away while it was fresh on my mind, but didn't consider the ramifications of my actions that deeply until driving home later.
