Hey try Webroot Secureanywhere complete.
its just 800kb and is about 25 times faster than kaspersky and mostly blocks all the infections.
i also have used kaspersky but i think this is the best.
Hey can someone please upload the cracked version of this antivirus software...
I need the latest version which is 8.0.1.184
or if someone could just upload a crack or serial for this version
