When I downloaded latest version via steam I get an warning from my system that it contains a Trojan virus which when removed prevents Steam from properly updating the game. So it is now unplayable.
I know it is Puzzlequest because I removed everything and restarted download and got the same error.
Wow, I’m getting the same thing and it’s driving me crazy! Is it an actual Trojan or just something weird with the latest build?
Waiting for Steam to get back to me.
It seems WebRoot is having a disagreement with Steam as far as I can tell. Multiple games are affected.
That blows, but does it mean that it isn’t really a virus?
Hi Everyone. I’m sorry to hear that several of you are encountering this issue. I’ve gone ahead and notified the developers of this incident, and hopefully they’ll be able to provide some insight when they get into the office tomorrow.
Steam player and I don’t use Webroot and had no alarms go off when I updated, just for comparison’s sake.
I have a Steam account that updated with no issues.
There are however known issues with latest Webroot update playing havoc with various Windows systems. Here’s an article.
Do you two use Webroot? If so, then it’s most likely their latest update that’s causing issues, since other Steam account users are reporting no issues with the update.
Found a solution on the Webroot support forums: https://community.webroot.com/t5/Webroot-SecureAnywhere-Antivirus/2-Steam-games-and-a-few-registery-files-deleted/td-p/290175
Apparently if you restore Marvel Puzzle Quest.exe from Quarantine, Webroot remembers it’s cool.
Working for me now.
