No, this is not a virus.

The authuser parameter is a way of controlling which Google account you're using (only useful if you have multiple accounts logged in).

From this blog post:

What’s controlling its choice? It turns out it’s the order you sign into the accounts. If you look closely at the URLs, either by mousing over the links in the account switcher or by looking at the URL you end up at for gmail but not for docs5, you’ll see an “authuser” or “u” parameter which is a low-valued integer. It starts at 0 for the first account you sign into, and counts up from there as you sign into additional accounts.

If you navigate directly to docs.google.com (or mail.google.com, etc), you’ll get the account currently associated as authuser 0, which is the first account you signed into.

I'm unsure what tab does, but hl changes the language (but not search localisation) - try changing hl=en to hl=de and see what happens (reference).

  • I see it's just that the webhp part got my alarm bells ringing – Dayle Gibson Jul 13 '13 at 20:40
  • That would be the "web-search home page". imghp is the "image search home page" at a guess. Definitely nothing untoward though. – Craig Watson Jul 13 '13 at 20:42
  • but this also appeared on another browser on my laptop – Dayle Gibson Jul 13 '13 at 20:54
  • Again, these are Google-specific URL strings. It's like going to mysite.com/page1 and mysite.com/page2. They will persist across any permutation of browser, O/S and computer, because they are how Google's website URLs are structured. – Craig Watson Jul 13 '13 at 21:46
