Kaspersky antivirus and internet security is one of the best antivirus tool available, 
since 2006 kaspersky is leading the antivirus market after the bitdefender.
I am a Ubuntu guy, so I less go in the windows but You might be using the kaspersky to clean up your PC.
Kaspersky gives a 30 days trail pack, to use their antivirus, after that kaspersky is disabled and its not possible to use the kaspersky antivirus, even you uninstall the kaspersky.
How to use the Kaspesky antivirus after 30 days trial.
Here are the steps :
1. Unistall the Kaspersky.
2. install the tool( kaspesky will say, that it is virus) but its not, i used ans my friend are using that tool to reset the kaspersky.
3. Download the tool [ here ]
4. Now run the tool, it will clean the Kapsersky restrickted registry keys.
5. Now you install the Kapsersky, it will activate for the another 30 days.
SO after 30 days do the same..

Kaspersky works better than Avg or Avast antivirus. Some viruses and trojan would not be detected by AVG but they are always detected by Kaspersky.

we can also do this by deleting registry files by :
regedit in cmd
and deleting all reg files of kaspersky

@abyscott, I didn’t tried that, may be deleting all the registries keys of kaspersky is not possible. Some of the Keys are in the critical registry holders,and that is unauthorized to our access…
