Solution

I my comp Google and Yahoo was blocked by some virus/Trojan/Spyware. Also when using IE many ads windows for pc cleaning used to popup and it was not possible to work. F-secure said some Spyware FraudTool.WIn32.AntispywareExpert. It was hell then on. I tried Norton, Avg antivirus but nothing happened. Although Avg showed some virus and removed it also. F-secure was already running and showing some or other virus and removing it but the problem remained same.

Some how i could point out two DLL files - Lataoxy.dll(Which was in the name Lataoxy.Oll) and ccbcbijs.dll. These were put in RUN with RUNDLL script. I removed these two files from C:\windows\system32 and from registry. All the problems solved.

Surpising but it works..
