I was browsing ebay this evening, and suddenly my Chrome browser redirected to a page that said "Critical Chrome Update". It was clearly adware or a virus as it had a dodgy looking domain name. How is this even possible? I was on a trusted website and it redirected me. Does this mean I have an infection already on my PC, or has ebay been compromised, perhaps by one of the ads running on their site? How can I tell if the problem is on my PC? I assume that as the browser redirected me, the problem was at ebay or their advertisers end. Thank you for any assistance.
