Over the past week or more I have had a situation start where I would get a message that a file in AppData/Local … was stopped just prior to execution. This is happening even after a fresh reboot without running any applications. It indicates the need to do a local scan as well as a boot scan. In almost every situation no virus is found on the standard scan and nothing ever shows up on the boot scan.
I have some files isolated should you want to view them to see if it is a false positive. Many of these files are given nonsensical names, have no extension, and no proxy is found running or installed that would execute these files to the best of my knowledge.
