It may just be me that is losing this thread but what does this mean:
"It is a pain and spoke to my Colleague it was PC world guy who place the skybot Malware and this is why you got this virus nothing to do with the copy of the 2007. "
When did your computer go to PC World and what for?
*********************************
You said earlier that:
"My work colleague installed Microsoft 2007 which he told not to update, as it was a copy and now i am getting a message from Security centre"
Microsoft (WHAT?) 2007
What ever this was, uninstall it, preferrably using
Revo Uninstaller
In the final clean up only delete entries in
bold type
***********************************
You have got some malware on your computer and it did not come from PC World.
As it is preventing you downloading the MalwarebytesAntiMalware (MBAM) and will also probably not let you download SuperAntiSpyware (SAS), you can download on another computer and save to a usb memory stick and run them from that when it is plugged into your computer.
So, on another computer and take a usb stick and plug it in.
Download
MBAM and save to the usb stick. Or save to desktop and then move the setup.exe to the usb stick.
Repeat with
SAS
Boot the infected computer in 'safe mode with internet connection' using the F8 key as soon as it starts.
When in safe mode, plug in the usb stick and install MBAM from it, update it and run a quick scan. Remove everything it finds.
Then install SAS and update and run a quick scan. Remove all that it finds.
Post back.
