ROBLOX doesn't have viruses. I don't think it ever had them.

What you need is Google Chrome and Malware-Bytes Anti-Malware.

Using Anti-Malware, you can do a complete scan on your computer for adware, trojans, spyware, and other malicious software that exists on the hard drive. It is limited, but you get more features with Pro.

In Google Chrome, you would want the DoNotTrackMe and Poper Blocker extensions in the Web Store. If there is no web store for you, update Chrome to the latest version.

Optionally, you can choose to go with Adblock, but because many sites reject it (not ROBLOX though), I can't give a say on it.
