To uninstall any antivirus fully, you need to run the vendor's own removal tool, or use an uninstaller which used to snapshots or monitors the installation, so there is a record of every file and registry key created. While IObit do not publish an uninstall tool for ASC Ultimate or IObit Malware Fighter, the Pro version of IObit Uninstaller will monitor the installation, allowing for them to be cleanly removed.What is also hilarious is that Iobit uninstaller will not delete any iobit registry keys, so if you have to uninstall it fully, use wise uninstaller or revo uninstaller or else it won;t uninstall fully.
RAM usage has nothing to do with how heavy an antivirus is. On my system, IMF is using over 700MB of RAM. While this could be considered excessive, it doesn't matter, as my system still has plenty of free RAM. Using more RAM, won't make your system run slower. I have many antiviruses installed on my test computer and RAM usage is something that I never take notice of. Perhaps the final version will use less RAM.I tried their anti malware 8 and it uses 1gb of my ram on idle. Like seriously, this antivirus is one of the heaviest antiviruses and it is even heavier than Bitdefender itself. The advanced system care is nice, but do not use the antivirus portion please.
