Secret vulnerability in Windows 7 triggered by red umbrella

According to foreign media reports, German anti-virus software developer Avira red umbrella recently said they will fix a mysterious vulnerability in Windows 7 when executing disk detection commands.

Early in the test stage, the test named it 《infoworlddetail shows that when chkdsk.exe is run to scan the hard disk, memory leakage will be triggered, resulting in the PC stopping normal operation. 《Infoworld.exe indicates that because the system administrator runs chkdsk.exe more often, the impact of this problem on IT system administrators is greater than that of common users.

It is reported that the only way to prevent chkdsk boot scanning is to disable this function.

Microsoft still did not comment on this issue, but some netizens said in blog and Forum comments that this vulnerability is related to Avira anti-virus software.

At present, Avira has admitted that it and other anti-virus software developers may have problems. "According to our current investigation, this issue may occur under specific circumstances. An operation on a deleted file may cause problems ."

This will cause the NTFS hard drive/Windows 7 kernel to identify that the file system is damaged and set a corruption flag for the NTFS partition. This in turn causes the system to execute the chkdsk scan at the next startup. In earlier versions of Windows kernel, the operating system returns only one error report.

Avira also adds that many other anti-virus software products will trigger the same problem. Avira will release a hot fix to the problem this week.

Knop said Microsoft may also release Windows updates to address this issue.
