Ran a scan today and Avast found Threat: Rootkit: hidden file, plus four other files that indicated Error: Data error (cyclic redundancy check) (23)
The rootkit is associated with:
C:\WINDOWS\assembly\NativeImages_v4.0.30319_32\System.Runtime.Cach#\0c4ec58f70e0fe6e74458c35fb260e2d\Syste.Runtime.Caching.ni.dll
The 4 files that indicated the CRC error were:
C:\WINDOWS\$hf_mig$\KB2509553\SP3QFE\tcpip.sys
C:\WINDOWS\assembly\NativeImages_v4.0.30319_32\System.Runtime.Cach#
C:\WINDOWS\Temp\FLT1985.tmp
C:\WINDOWS\Temp\FLT1986.tmp
A boot scan did not yield any problems.
A subsequent Full System scan yielded the same result as above.
I cannot move the file to the chest, repair it, or remove it.
What are my next steps to remove this? Is it a legitimate threat?
Thank you!
