Avast! Falsley Claims Steam is a Trojan

If you're a Steam user as well as one of the many users of Avast! Antivirus, you probably ran into a problem on Sunday where Avast! falsely deemed Steam as a trojan and locked it up in the vault. The definition that listed Steam as a trojan was taken back about an hour and a half after it was released. For some odd reason, I had no problems even though my computer was on, Avast! was running, and Steam was open. But if you were affected, you just simply have to reinstall Steam. If you can before you uninstall, try to backup your steamapps folder (C:\Program Files (x86)\Steam\steamapps if you're on a 64bit system or C:\Program Files\Steam\steamapps if you're on a 32bit system) then copy it back to the same place you found it after Steam is reinstalled. This will allow you to not have to re-download all your games again, saving you a lot of data-usage, time, and hassle.
