I updated Windows yesterday morning and in the afternoon when I got my scan report it said:
File Name
C:\Windows\Installer\224180f.msi|>Icon._542830EA6FE6_4FFC_94F9_C86E629E90BC.exe
Severity
High
Status
Threat: Win32:Trojan-gen
Result
Error: The operation is not supported for this type of archive. (42111)
What should I do?
If you restart and scan again…is it still there?
No! It’s gone! 
Thanks for your help. This started yesterday afternoon when I did a quick scan and was told it moved a file from the same folder to quarantine. Just to make sure I got everything I did a full scan and that’s when the message I posted came up. I did a boot time scan and the same message came up. Because I rebooted once, I didn’t think rebooting again would have made a difference, but apparently it did.
So now I need to ask because this was a Trojan, do I need to change all of my bank passwords and so forth? I haven’t done any transactions in the past few days, so the only passwords I used are on sites like this. What do you think?
