Hello everyone - Seems Avast4 (free version) is taking up a lot of my hard drive space under DATA/moved folder. All the files are labeled in numerical sequence as :msi.dll.###.vir. There are currently over 5000 of these files in my data folder and each one is 1.83mb in size - which means it's taking up over 9 gigabytes of my hard drive space. That seems extravagantly huge. I really like avast but is it safe to delete these files? anyone? Thanks in advance!
