This question already has an answer here:
I installed the popular software 'Synthesia' from its official website. It is a program for piano transcriptions. It has always been safe.
I decided to uninstall it and as soon as I uninstalled it, a virus came up. I mean, I tried to uninstall it from the Panel Control > Programs [list] > Uninstall a Program.
The uninstall.exe stopped and a warning from Avast came up saying that the .exe has been stopped and the virus [Trojan] moved to the chest [Avast virus chest].
I checked it out and it is quite strange because the name is au_.exe found in the Temp Folder -- C:/Users/MyUserName/AppData/Local/Temp/~nsu.tmp
As Avast has reported the virus is a FileRepMalware
I decided to scan the computer but nothing has been labelled as infected.
Anyway, the software is still there, not uninstalled. How can I remove it if the uninstaller is infected?
p.s - as far as I know, au_.exe is a virus. au.exe is not a virus, at all. Anyway I got the first one so it is a virus and not a false positive of course!
