If downloaded from roblox.com, the ROBLOX client should not contain any viruses. It's when you download ROBLOX from somewhere other than roblox.com, download extensions for ROBLOX that are not officially endorsed by roblox.com, or visited a malicious site about ROBLOX (like going to a website that claims you'll get free ROBUX by visiting) do you risk unintentionally downloading a virus.

Remember: just because those are the only programs you downloaded and installed (I'm assuming you have downloaded things like images, pdfs, word documents, etc.) doesn't mean that there may have been other things that were downloaded and installed onto your laptop without your knowledge. If you haven't already, I really recommend installing a good antivirus program (I use AVG) and an internet filtering program that will automatically block a site if it is found to be malicious (I use K9 Web Protection).
