Microsoft Security Essentials has been blocked by the virus inducing the firewall.
Even if I type virus security into chrome the virus crashes the browser.
It gives warnings about the danger hardware damage.

Hello ramendra and welcome to Seven Forums.

It sounds like you're going to have to use a malware scanner that can start its scan before Windows 7 boots. Microsoft has a free tool called Windows Defender Offline (not to be confused with the Windows Defender that might have been bundled with Windows 7.) It's suggested that the scan media be created on a computer that is malware free.

What is Windows Defender Offline?
