I'm with the same problem, running sfc /scannnow. But in Windows 8 x64. I tryed to restore files from Malwarebytes quarantine, but i didn't have sucess. It's Installshield files. I will try again the solution (don't work fomr me) @ http://www.sevenforums.com/system-security/261979-help-zbot-infection-4.html Maybe after a good coffee, things come more clear.
Yes. I'm running Windows 8 x64. After almost an heart attack, i manually inspect the files... Same MD5, SHA1 as listed in National Software Reference Library. Nothing malicious or new in the code. _isdel.exe SHA256: 1e97eca81395d1bd5e627debfdb02828bd3655d68c8f7296395d574781faa32e SHA1: 0e7bb331d398be694a92a823de839fefdf464dfd MD5: 9d4ec4b71fd189a0b2c4dbd6aade16bf
