Ever since I ran a full scan a few days ago with the Kaspersky Rescue Disk on my Mom's laptop, it has been running very slowly. I don't think it was from the Rescue Disk, since it found nothing. It is a few year old Compaq laptop, with a Pentium Dual-Core, 3GB of RAM, and a Samsung HDD. I ran a test on the memory and HDD, and they both were fine. It takes a while after logging in just for Avast! and OA free to load, and a while longer to be able to do anything. I checked resource monitor after I finally got it to load. The disk i/o was maxed on the little graphic, at at 100% it said. The main ones were: svchost.exe (netsvcs) C:\Windows\SoftwareDistribution\Datastore\DataStore.edb svchost.exe (LocalSystemNetworkRestricted) C:\$Mft (NTFS Master File Table) PID 1000 There were lots of the second one with PID 1000, but the C:\$Mft one used the most disk i/o Also at the very start after logging in were two explorer.exe 's. One was in the Windows folder, the other in C:\Users\*\AppData\Local\Temp Is that normal? Should there be an explorer.exe there ever? It was using a lot of disk i/o, but it went away after a while, and I could never find it in that folder. Any input appreciated.
