Microsoft have warned users numerous times not to download leaked Windows 7 builds because of the possibility of modified or infected images. Users should understand the risks involved when downloading and installing leaked builds, as we continue to see an increasing amount of fake build releases.

Unfortunately, one of the first build 7100 leaked on “the bay of pirates” was modified. Many users jumped on this build right away, not realizing it was modified and infected with a trojan. The torrent was later taken down. Even if you did not download build 7100 from the suspected site, you should still always do a hash check to ensure your image was unmodified. You can check the MD5 hash of an image by using MD5Checker (download here). Users in our forums and our home page only report on leaks once confirmed to be real, and will always include hash information for you to check with. Thanks to vistademon who spotted the infection with the image uploaded by Einsteinjr.

Leaked Windows 7 Build 7100 image may have been infected with trojan

The image had the following incorrect build string: Windows_7_Ultimate_x86_RC_Build_7100.4866522
This is the MD5 hash of the infected image: 2dc70d7c851d76d49ac71167141222f7
The correct hashes should be the following as reported by our forum members:

x64: 98341AF35655137966E382C4FEAA282D
x86: 8867C13330F56A93944BCD46DCD73590

If you believe you have an infected image, you should get rid of the image immediately, update your anti-virus software and do a complete scan.

If you were a victim of the infected image, it may be better to wait until May 5th when Microsoft releases Windows 7 RC for public download. Download safely. (Story Link)

Thanks for the MD5 checksum. Reaally needed it.
