    Hey guys,
    Long time user of 7zip, first time having any issues.

    So, like the topic says, 7zip is reporting any archive I try to extract as broken. The same archives unzip fine with winrar. I've tried both the 32bit and 64bit version of 7zip but with no success. This is on a relatively fresh install of windows on a new box. I've tried uninstalling and reinstalling several times. I'm stumped. Any thoughts?

    7zip version: 9.20 32bit and 64bit
    Windows 7 sp1 64bit.
    Intel core i5 3337U
    RAM: 4GB

    Edit: Just to add to this, I did a little test. I took one of the "broken" archives, extracted it using winrar then compressed the extracted files with 7zip and extracted that archive with 7zip successfully. Not sure if that helps.

    Wonder if some malware may have affected your existing archives, such that 7zip now treats them as broken?
