I have a tip for you that will reduce scan time- any scan time!
Either do a disc cleanup or run TFC:
TFC (Temp File Cleaner)
Download
TFC to your desktop
- Open the file and close any other windows.
- It will close all programs itself when run, make sure to let it run uninterrupted.
- Click the Start button to begin the process. The program should not take long to finish its job
- Once its finished it should reboot your machine, if not, do this yourself to ensure a complete clean
TFC only cleans temp folders. TFC will not clean URL history, prefetch, or cookies. Depending on how often someone cleans their temp folders, their system hardware, and how many accounts are present, it can take anywhere from a few seconds to a minute or more. TFC will completely clear all temp files where other temp file cleaners may fail.
TFC requires a reboot immediately after running. Be sure to save any unsaved work before running TFC.
TFC (Temp File Cleaner) will clear out all temp folders for all user accounts (temp, IE temp, java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
When you run Kaspersky or any other scan, it has to scan all the files. So get rid of the trash first. You should notice a marked reduction in any scan times.
And good computer maintenance has you do a cleanup first, then Error Check, then defrag, in that order.
