@jamesbeardmore said in Recommendations for anti-virus to replace Avast Premier.: Sorry to resurrect an old thread but yes, you read it correctly, 1.2 GB - but that's with a bunch of custom databases in addition to ClamAV's standard databases. Don't worry - the thread is still going far as I'm concerned I'm not so much worried about memory usage during a scan, since that's something I'm doing rarely anyway. It makes sense that it would load the database into memory when scanning, for speed of lookup. What's more interesting is the memory use during regular background usage, and to a certain extent CPU usage during such background monitoring as well, but it's harder to get data on obviously. For instance Avast in the background uses ~80MB, and to be honest I doubt I'll be able to find any that uses less. loads of fluff, big fonts, vast white spaces and dumbed-down options for idiots. I know, it seems every single AV solution is following the same UI design now, in the end they all look exactly the same... all for the sake of being "user-friendly".
