[Browser search engines stop working]

Hello, 

I just download Kaspersky Cloud Security Free Anti-Virus and I'm now experiencing a problem of browsers "cutting connection". This led to my search engines not working and most websites to stop functioning. If anyone knows the solution, I would really appreciate it since this is a very urgent situation that I need resolved as possible. Thanks.
