Since Kaspersky is a commercial product you can only download a trial, however shareware such as AVG free (http://free.avg.com/au-en/homepage) remains free for non-commercial use and is compromised of all the features you would find in a commerical anti-virus software product.

Only single antivirus cannot help u out in tough situations ,
You need a combination of softwares to help protect ur PC .
Here is the combination that I use
Avast antivirus > Malwarebytes > Super Antispyware > Comodo Firewall .
u can use AVG or Avira FREE in place of Avast , thats ur choice
As Far as avast is concerned , u need to register for free , give them ur email address and they will send u a free licence key for avast (i.e. for 1 year ) and u are entitled to use the software for 1 year !
U can get the above on following addresses –
Avast – http://www.avast.com/eng/download-avast-home.html
AVG – http://www.free.avg.com/
Avira – http://www.free-av.com/
Malwarebytes – http://www.malwarebytes.org/
SuperAntispyware – http://www.superantispyware.com/download.html
Any one of the following Firewalls -
Comodo Firewall – http://www.personalfirewall.comodo.com/
Zone Alarm Free Firewall
http://www.zonealarm.com/security/en-us/zonealarm-pc-security-free-firewall.htm
These apps work in combo to protect ur PC , and provide rock solid protection against viruses ,and all are free !
Good Luck
