Hi, I have ESET Smart Security installed and i want to install another free Antivirus as on demand scanning. Is there any free Antivirus has this choice on installing? Thanks.
Avast or Avg (Passive Mode) https://support.avast.com/en-us/article/43/ http://www.avasthelp.net/technical-help/avast-passive-mode/ https://support.avg.com/SupportArticleView?l=en&urlName=How-to-use-Passive-Mode&supportType=home
Plus im not to sure in it's ability's anymore, There's been no talk about it or any updates in a long time now.
It is preferable to use on-demand scanners. They do not conflict with realtime AV and malware can not easily block them. 10 Free and Portable Offline Antivirus Scanners P.S.: Portable for on-demand scanning of the computer, as for on-demand scanning of files (right click), it is better to use passive mode.

Malwarebytes, Zemana, Emsisoft Emergency Kit and HitmanPro are all good choices and will work fine alongside your antivirus. If you want to try Zemana, download it from the free download link, halfway down the following web page, to get the free version. https://www.zemana.com/en-US/AntiMalware If you use the download link on the home page, you get a trial of the paid version, not the free version.
Note, that Zemana installs a driver, which stays there forever, even after uninstall or when you use the portable version, it could cause problems.
The only free antivirus I know of that can install has a on-demand scanner is Adaware. Advanced SystemCare Ultimate installs in compatible mode if there is already an antivirus, however, it's not free.
"zam64.sys" and "zamguard64.sys". I did this a few months back to remove leftovers, but it should still work. I was surprised myself, that a portable version is not really portable.
