False positive SVC rootkit notice (?)

Viruses and worms
1

I was doing a Windows Update for an optional nVidia driver update and a required Windows Defender update. All of a sudden I got an SVC rootkit warning. I had two options delete and ignore, so I clicked delete.

My computer restarted and automatically started a boot scan. I esc’ed out of it. I did the Defender update only, ran the Avast MBR thing (aswMBR or something like that) for a couple seconds. At the top of the output it said normal Windows 7 MBR. I ended it, scheduled another boot scan and restarted. Give that computer 40 or so minutes and the bootscan should be done. What should I do now?

If the boot scan comes clean I will immediately run MBAM. Assuming both the boot scan and MBAM say I am clean, is there anything I should do?

Just to note, I did a boot scan on Tuesday and it was clean then. I barely used the computer on Wednesday and Thursday.

Boot scan clean. Initiating MBAM then OTL.

3

MBAM clean
OTL log attached (it was the only one that generated)

From what I see the log seems clean.

Anyways. I am shutting down and going back to Skyrim

Please tell me if anything this off.

I would go with a False positive on this

Avast was probably scanning and the file did something unusual

5

ok, I am running aswMBR quick scan right now and

Service TrustedInstaller C:\windows\servicing\trustedinstaller.exe Hidden

is show up red

I haven’t done anything to TrustedInstaller.exe. I scanned the file itself with Avast right-click scans and MBAM right-click scans. Nothing wrong found.

No it is just because it is a hidden windows system file
