Virus chest and Other issues

[jefferson sant]

I updated to new free version Avast 17.1.2286, when clicking
icon for and quick access to quarantine, but functions not were. After uninstall avast clear and go to a new installation, only scan option does not run.
Opening through the interface-> Protection-> Antivirus -> Virus chest
They all work without any problem.

During the execution of the old file
Tested in the last year this same had the detection Win32:Malware-gen [Trj].
Made recently with test in the VM with Windows XP SP3 analysis done by DeepScreen the file was moved to quarantine.Today, both in the media and in the PC, there were very different.

The doubt is then in this case the file already contained a definition.

A good start would be removing all illegal software from your system.

Yes. Now that testing at least antivirus has detect the most. Some are corrupted, I have already found defects in the scans when the previous version when I click the quit button
The scan is canceled, with the new version it is possible to note that the removal continues in progress even after closing the window with results. Previously the cleaning of the infected files was done faster as 200 or more the results were successful, the process is now made slower.
The files is not detected since the good time or detection has been removed for some reason.
