iv got windows 7 and got a notification from avast saying my anit virus had expired and to download a new one, so i followed the link to update it and when it had finished all my files were missing. i then started the laptop on safe mode and all the files were there but empty. for example in my film folder all the titles were there but when u clicked into it they wer only like 25kb in size an wouldnt open. any help would be greatly appreciated.
Welcome to the Avast forums, Jeff.
Is it only media files you are having a problem with? Is your system operating normally otherwise? Please run a quick scan with Avast and report the results. Also, if you don’t already have Malwarebytes Antimalware, please download, install, update, run a quick scan, and report the results.
