Hello suzilu,
The RootAlyzer is an analyst tool and not a scan and fix program.
In general all items found by the RootAlyzer are not necessarily malicious, sometimes legitimate software uses rootkit technologies.
If you suspect an infection it would be best if someone can take a look at the system in the Malware Removal Forum
Please start a new topic there, the forum's FAQ includes instructions in post #2 on how to provide the logs from Farbar Recovery Scan Tool and aswMBR, which are the logs used in the preliminary analysis.

If you cannot produce the logs start a new topic there anyway and let the helper know.
Best regards.
