Hello Peter,
Like iPanik said, you can exclude some types of files from scanning, however this won't help much, as Kaspersky File Scanner by default will only scan the new and recently modified files.
If you really want to increase the performance of the scanner, I would suggest that you set the File Anti-Virus feature to "Low". What this means is that Kaspersky will scan the files by the extensions.
If you have selected Files scanned by extension as virus scan objects, File Anti-Virus or a virus scan task scans the files with the extensions listed below for viruses.

Kaspersky Internet Security 2013 is a suite which will allow you to perform a lot of tweaks. To improve the performance, you can also try some of the below tweaks:
1. Enable 'Concede resources to other applications'
When Kaspersky Internet Security runs scan tasks, this may result in increased workload on the CPU and disk subsystems, which impacts other applications' performance. By default, if such a situation arises, Kaspersky Internet Security pauses virus scan tasks and releases system resources for the user's applications.
2. Uncheck "Perform regular rootkit scans"
While running regular scans for malware is advised, I noticed that Kaspersky will "Perform regular rootkit scans" at my computer startup, slowing down for up to 10 minutes.
I would advise you to uncheck this feature, and instead perform regular manual scans for malware.
What are you computer specifications? Are you experiencing any major slow downs with KIS 2013 installed?
