I am using Ubuntu 14.04.My computer is infected by viruses or malicious software installed without my knowledge during web surfing. I am saying this because whenever I search anything in Google search it is showing me only the error message that we are sorry, we cannot process your request, so I visited the help link provided by Google & tried all the steps instructed there but could not resolve the issue. There I am asked to scan my system because my computer has been affected by some malicious contents.In addition with it I would like to inform that I have installed wine software in order to run Windows application in Ubuntu & installed idm.Can anybody suggest me how do i get rid of this problem.

I installed clamav, scaned the computer using clamscan. Got the following results

/initrd.img.old: Symbolic link
/vmlinuz.old: Symbolic link
/initrd.img: Symbolic link
/vmlinuz: Symbolic link
----------- SCAN SUMMARY -----------
Known viruses: 2424225

Infected files: 0
Data scanned: 0.00 MB
Data read: 0.00 MB (ratio 0.00:1) 
Time: 4.375 sec (0 m 4 s)

yet i don't know whether my problem is resolved or not because it is showing the known viruses 2424225

    It's extremely difficult to be infected by such a malware on ubuntu. Seems like a settings problem with your browser. Try using a different browser for google search. Also paste the contents of /etc/hosts file here. – Ashish Jul 20 '14 at 12:34

    Could you paste information from below commands to paste.ubuntu.com: route -e, ifconfig -a, cat /etc/hosts, cat /etc/network/interfaces, netstat -nputw – c0rp Jul 20 '14 at 13:17

First, your ClamAV install shows that there aren't any viruses on your Ubuntu install (The Known Viruses entry simply shows how many Viruses ClamAV has in it's scanning database). Secondly, the reason you're receiving the error with Google is most likely not due to the fact that you have a virus on your Ubuntu install (Linux and GNU user-space works a whole lot differently than Windows (unimportant)), but rather that you have another infected computer on your local network, are using an infected VPN to connect, or your IP was recently changed by your ISP to a previously-malicious address that Google is blocking.

You might want to change your IP, as it may have previously used to host a malicious address that websites will block. If you don't know how to change your IP, look at this guide, How to change your IP in Ubuntu, while that guide is for an older version, it should still work. If that doesn't work, call your ISP and ask them to change it for you.
