Avast! found viruses during MBAM scanning progress

Hi,last week I just scanned my mom laptop with MBAM.But it was something weird happened.During the scan,avast! detected five viruses at process “MBAM.exe”,but different file location.Could it be a false positive?Now,the five viruses still in the Avast! chest.Lastly,MBAM only found six viruses but is all different from Avast! If MBAM log is needed,please feel free to ask for it.Thanks and Regard.

Hello,
send us (virus@avast.com) the files to analyze, please. Put “False positive” to email subject, pack the files to password protected archive with password “virus”, without quotes.
