Title: Win 32:DH-A1
Post by: REDACTED on March 18, 2017, 01:37:42 AM

Hi,
  I just ran my monthly full system scan (on Avast! free edition). It found something called 'Win32DHA1.'
After the scan, I clicked "fix automatically". Is that all I need to do, or should I have put it in the vault?

Since you did a static scan of your archival files, this detection is related to a PUP or PUA detection. 

Not to worry about. 

A part of a file detected would have had elements where unwanted advertising or scumware may have been present.

If you wish to save a file for later retrieval use quarantine instead of fix automatically to avoid deletion.

Fix automatically default action is to quarantine.

Thanks, Aikhan. I was confused at first because I didn't see it in the virus vault - I wasn't sure if it has been dealt with properly. A second full-system scan didn't detect anything, so I *think* it's been taken care of.

Archival files do not do anything to your system unless you or a program/process opens the file.  Avast, when used by you to scan all files (full scan), opens all files that it can and checks the contents inside.  Avast is your program or process performing the action in this case.

A manual scan (monthly scan in your case) is one that you initiate.  Real-time scans are what block malware from ever running on your system.  So it is the real-time scanning you can count on to protect your system from harm, and the manual scanning you do will give you peace of mind.  A manual scan does not actually protect your system from harm, the real-time does.

Suggest changing your default action to quarantine first then fix automatically so you can recover a file if need be and it is found to be clean in the future. 

I thought that might be the case so as why no quarantined files were found by you.

Someone asked how I knew detection was archival:  See attached below.

Ran a full scan sometime ago, and avast was set to detect PUPS.  All files went to quarantine.  Note the detection.
