The page documenting the malware it targets (see above), shows only two strains were added in all of 2017.Generally, an effective security program requires that we monitor software vulnerabilities and identify available patches and updates befitting our needs. On the other hand, MSRT is very limited in scope. You make a copy of MRT.exe on a non-infected PC, rename it to SomethingElse.exe for good luck, and run a full scan with it on an infected machine. The 32bit edition is currently Windows-KB890830-V5.48.exe, the 64 bit edition is Windows-KB890830-圆4-V5.48.exe.Ī nice thing about MSRT is that it's portable. MSRT can be downloaded at any time from here. When its run as part of Windows Update, it only does a Quick scan. Running it manually offers the option of a Full scan. When you run it manually, the initial window has a link to "View a list of malicious software that this tool detects and removes." The May 22nd version includes Win32/WannaCrypt in this list, the May 9th version does not. Or, you can find it at C:\Windows\system32\MRT.exe You can run MSRT manually by simply typing "MRT" into the Run box. However, when asked, a company representative said that the May 22nd update was "to detect and remove WannaCrypt malware." WannaCrypt is another name for WannaCry. What changed? Initially, Microsoft didn't say, the home page for MSRT, had not been updated as of the 25th. The May 9th release was version 1, the May 22nd edition is version 3. Sure enough, running Windows Update on the 25th, installed a new version of the software (shown above). I checked a 64 bit Windows 7 machine that had been updated on the 21st. Windows Update installed MSRT on May 21st and then again on May 25th
