Found the one who created the virus by getting into his virus and getting all the information from it. Report him all if you want.

He isn't the only one, it's just one of many accounts. There are many people redistributing the virus.

If anyone else is a victim of this, you should make a Steam Support post. They usually return your stuff since you never accepted or made the trade, it'll just take sometime.

You can easily find out where the items went by checking your trade/inventory history, no need to "get" into the virus and possibly make matters worse for yourself. Even if you did you probably aren't going to find anything other than a trade URL.
