I had the Smart Security on my PC, it decinstale, and download Avast Internet Security 7, the official website of Avast. But when I saw my aviation images I deleted half of my files, notwithstanding that the said registration estava not infected. And I’m not the only one because my sister also install the Avast Internet Security 7, which was that you download, just that she had installed Norton Internet Security and also did the same.
Someone could explain what happened, as my files can not recover because I realized very late and aviation subscript on them.
avast does not delete files that are not infected…so something else is wrong on your comp
if you was infected with the rogue SmaretSecurity…then you need to get you comp checked for infection
which was that you download, just that she had installed Norton Internet Security and also did the same.never install more then one antivirus, or you will get all kind of mysterious windows errors and false positive detections
to check for infections, follow this guide and attach (not copy and paste) Malwarebytes / OTL / aswMBR logs
