Thank you for updates above i have Just had a Jason on the phone telling me I had a Trojan on my computer and that i shold delete file csrss.exe and he would talk me through it. i told him my laptop was at work and I was only home for lunch so I took his number which was the same as one above 02202868331 and ext 8005. after reading the comments above I am glad I did not delete this file as it is a scam to gain access to your computer.

SCAM SCAM SCAM!
Another obvious scam using a currently familiar theme, complete with equally familiar fake posts from satisfied customers using "call centre" English!

That would be "James Anderson" who has called me previously.  Funny but I have just been watching him on TV with the England Cricket Team in the UAE.  He really gets about, doesn't he. The telephone number is fake, via Skype or VOIP and the call would be from India. This scam has been going on for ages and was on "You've Been Scammed", BBC1, last November. They want remote access to your coputer and will install spyware/malware to steal your info. As you ISP told you, neither Microsoft or its partners would ever 'phone you.  It would be a breach of their privacy rules.  No-one who 'phones has any knowledge of your computer. They rely on scare tactics and lack of computer knowledge.

It is sad that you have to resort to abuse, even if it is complete gibberish.  A check on the Microsoft website will show the warning that neither Microsoft, nor its partners would ever 'phone.  It is a breach of their privacy rules. Your choice of places where people have been helped is a joke, you cannot even spell them. Your post just shows how much of a scam this company is. Thanks

Hey "Greame" Smith, the next time you try to sound genuine by using an English name, at least learn how to spell it!

I too had a call from that very famous company and they told me that my computer is infected with a trojan fileI was amazed that how do they come to know that,however they gave me assurance that they are not any xyz company and can certainly  help me to sort the mess out. I gave them the access of my computer and Jesus my  computer was working fine.
