everytime i open any google services on firefox i got redirected to sorry.google.com telling that my query looks similar to automated requests from a computer virus or spyware application. is there any way of fixing this manually. i hate installing anti virus because it slows my pc. i just make a careful judgment before installing or running a file from internet. thanks.
Google can say sorry only if you use some software which continuously pin Google. There seems to be some spyware which is pining Google. Ask your hardware experts to find it and remove.
