Bugcheck f4 0x3 0xfffffa80074c5b30

Question

I installed mozilla firefox and I was asked to upgrade it because the version I had installed an outdated version. Once I installed the upgrade,my computer shut down and,after I ran start-up repair, the following root cause came up: bugcheck f4 0x3 0xfffffa80074c5b30
What does that mean and what am I to do to fix it?I tried to restore it to an earlier date but it doesn't work. My operating system is Windows 7(a friend installed it for me and it is genuine) and I have Windows Vista if re-installing the operating system is required.
Many thanks.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
* [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
* [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
[http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
