Is there any way that avast can tag this tool as "safe"? There are too many confuse to user that think it is virus. But infact, this tool is clean.
Until the virus database will be corrected, as a workaround, you can add it to the two Exclusion lists of avast:
For the
Standard Shield provider (on-access scanning):
Left click the 'a' blue icon, click on the provider icon at left and then Customize.
Go to Advanced tab and click on Add button...
For the other providers (on-demmand scanning):
Right click the 'a' blue icon, click Program Settings.
Go to Exclusions tab and click on Add button...
You can use wildcards like * and ?.
But be carefull, you should 'exclude' that many files that let your system in danger.
