How Do Online Virus Scanners Work?
- by user185812
I have seen a lot on free online virus scanners available online lately. I was considering trying one of them out, but I have a question. If I have company word documents, excel spreadsheets, etc on my computer, do these scanners just take a copy of everything on my hard drive, put it on their server, and search through them? Or do they just use virus definitions and scan through my computer without taking a copy of all my data?
