I doubt it's malware, but a few scans from a single user mode boot disk while the actual OS is offline maybe isn't a bad idea. But it could also just be that the CAPTCHA is hard because the site cranked it up for non-US users, if you're not in the US like I am. There are many EU and Asian countries where I flat out cannot access perfectly benign websites (e.g., Home Depot†) if I'm shown on an IP from these countries. So scan, but I doubt it will find anything. † true, when I was in Georgia (the country) during the time that Home Depot had the huge skeleton yard decoration, I couldn't even access the Home Depot website to look as Home Depot was blocking it. The page would resolve and load, but Home Depot served up a 403 for every page. Using VPN with the US or western/northern EU countries worked, but eastern EU countries also got 403.
