    "Resource Leach"

    June 27, 2012  |   By Andrew91352


    Seems to work fine otherwise. It's FREE!


    The program uses up about 50,000k in resources on my PC during my busiest work hours. It seems to only want to run when I need my PC running at its best. I will hang for about 1 to 2 minutes before getting access again. It just stops everything .


    I hate popups from other providers but at least my pc ran faster. I'll try this later after a few versions are released and bugs are fixed, though this isn't really a bug as much as a useless drain of resources for redundant operations.

    You obviously have leftovers from one of your previous antiviruses; this causes havoc with MSE. Go to your other antivirus sites and download their complete removers to get all leftovers. All good antivirus programs will hang and peg resources when the previous a/v was not completely removed. This is a common problem when changing a/v's.
