zipper file infection alert

I have been getting notices about infected zipper files. When I do the scan, it shows no infected files. I will post the answers to questions I found earlier. Can anyone tell me what to do with the alert?!
Thanks…I’m clueless in CT!

  1. How was it detected? What was scanning, you yourself or the back-ground scanner? When did the message occur on a download, unzipping, opening a file, mail or mail-attachment, etc.? Message first appeared on start up, now shows intermittently.
  2. What was the source of the file, where did the file come from?.: e.g. address, URL, source. C:\SystemVolume
  3. When was it downloaded or received? A few days ago
  4. What is the exact file name with extension. S0034855.Acl
  5. What was the exact wording of the message that the AV program came up with? This is important for later. A virus has been detected

I’m assuming that the alert came from avast.

If so avast give you options to choose from (see image for example), the key should be ‘first do no harm’ don’t delete, send virus to the chest and investigate.

However because the c:\System Volume Information folder is a part of the system restore function and as such is protected by windows, the only way to clean infected _restore points is to disable system restore and reboot. This will clear ALL _restore points. Once you have disabled system restore, reboot, scan your PC again and if clear enable system restore.

Well, I followed your advice. I think that it may have worked because I have not received the alert again. Thank you very much for your help!
