Spyware or Search problem in Google - give 403 forbidden

When i search today from my FF browser, I saw this problem:

Is it my problem, I use Free-AV (Avira free edition). Didn't find anything.

 

We get this in our offices too, I believe it is because of extensive searches from similar IPs

 

I have had this once in the past, and I just went back on to Google, and repeated the search. I think it is nice to see Google taking these measures, I also like the one where Google disables the live link and gives you a similar warning about the site possibly containing malware/spyware/viruses etc.

 

Last our, I talk with my internet connection provider.
He said, Just uninstall Firefox & delete manually its all files which are not removing after uninstall.
I do that & problem is now solved.
He said more, That is problem for one virus. This virus position is in FireFox folder. But free-Av can't detect this virus.

 

i always get that google error when i use a Russian proxy but when i use without a proxy i dont get the error

 

That's is probably because Google has blocked queries coming from the proxies server IP.
