|I have had a trojan called Trojan:Win64/Sirefef.b|
since 11/11/11 which got allowed after me thinking it was only a keygen false positive now my hotmail account is blocked and recently more viruses appeared in Microsoft security Essentials since 14th of november called Trojandownloader:Win32/Waledac.C , Backdoor:Win32/Kelihos.B and another Trojan:Win64/Sirefef.B.
Only the first Sirefef.B says its "allowed" and i cant disallow it or i couldnt after i allowed it (big mistake) first. But i think there might be even more spyware and i was told by my brother to format my computer. How do i go by step by step?
