No, that is not a Virus, but it sure does sound like adware. This is a common problem and although this one sounds like it is not dangerous, some adware/malware can be and will slow your computer to a crawl or worse.

You will need to scan your computer with these three softwares. Install them, update them, and then scan with them. You will be surprised what you find.

Avast is an anti-virus software ONLY. It will not pick up adware/spyware/malware. Use the softwares listed below to do that. They are free, and effective.

Unlike AV's, you can run as many of these as you want as each are set up to pick up different things. In fact, the more the merrier. You should scan with these, at the very minimum, once a month.

It sounds like this malware got loaded onto your friend's Flash Drive and is now trying to, or is installed on your computer. Make sure you know where that Flash Drive has been before plugging it into your computer. I would recommend wiping that Flash Drive clean and trying again.
