Always when a theat is found, blank windows pop up and it is impossible to go any further. I often use unusual.exe files, and there is no option to allow the file to open. Any answers? Thanks
There is no option to allow execution of a file from the detection pop-up if the file is deemed either suspicious or malicious.
However you can provide us with a sample of the file so we can fix our AV-databases, if the detection is a false positive.
You can still add either the location (folder) of the file or the file itself to the exclusions list (under Computer Security -> Settings -> Virus and Spyware scanning -> Exclusions) to exclude the file from Real-Time scanning. However this is not recommended if you aren't sure the file is indeed clean.
