Due to lag in my online gaming, I ran "trojan killer" to see what may be the cause, trojan killer suggested that this is a trojan/malware. Since it was located in my temp folder I tried deleting it, but It wouldnt delete giving the following message: "the action cannot be completed because the file is open in Windows host process (Rundll32)" Some information about the file: name: Rpcqt.dll file description: Ad-Aware Installation package company: lavasoft version: size: 22.1 MB Generally im concerned with files that dont allow me to delete them, especially when they are in my temp folder.
It is a virus when in the temp folder. The size of the virus is 22.1 MB. Upon mouse hover the file claims to be from Garena. This is virus. Delete Immediately!!
it's a required file if you're playing online games. It verifies that u are not using hacks in your games.
