I ran a scan recently and found that I was infected with what’s known as an Injector virus. I can’t recall what the full name of the file was, but in the scan logs it has it listed under “C:\WINDOWS\system32\MCSysUtil.dll”. It will not let me delete it, repair it, or even send it to the chest. What steps should I take from here?
upload the file to www.virustotal.com
and post the link to the results here.
it could be a possible false alarm…
What is mcsysutil.dll doing on my computer?

I tried using virustotal but I couldn’t find the file. I even went about searching for it through the windows search setting and still nothing. The post Pondus posted asked me to run Speedupmypc, but I have CCleaner and I always run the registry cleaner, so what else is recommended?
The post Pondus posted asked me to run Speedupmypci gave you info about the file
mcsysutil.dll is a Manna System Utility belonging to Metamail from Metamail Corpsomething you know?
Of course and I read all of the information that link listed, but it recommended I do a scan with SpeedUpMyPC, which I doubt will resolve my issue. At least I would assume that since I already use CCleaner on a daily basis to search for Registry Errors and as a clean up utility. I tend to do all the necessary steps to keep my laptop up to speed including checking for bad sectors through properties on drive C: (once a month). Maybe I deleted a registry that was needed?
I’ll await any instructions that are needed for me to move further with my issue. Thank you all for your time.
SpeedUpMyPC, which I doubt will resolve my issue.it is just an ad as many of these websites have
That may be a false positive, could you upload to Avast as an FP
Hello essexboy, I remember you helping me out in the past and resolving my problem, so it’s nice to see that you’re still around. How exactly would I go about uploading it to avast as a False Positive? Would that be the same as submitting the file to the virus lab?
Yep just the same, are you running V7 or V8 of Avast
V8 … Go to support and select report file
I’m using the most recent version of Avast and I went ahead and submitted it through the virus chest instead. I have no clue how it’s in the chest if it said it couldn’t be moved there, but it’s there now.
Rescan it from the chest tomorrow and see if it still reports it. Has the removal affected any of your programmes at all ?
Not that I have noticed, but once again my laptop is starting to run a lot slower than usual. I had recently uninstalled advanced system care and replaced it with CCleaner with the advise of a member on here, which seemed to have corrected my speed issue for a while.
I can have a quick looksee if you wish
Sure, just let me know what you need me to provide you.

The logs look nice and clean … Are you experiencing any problems ?
I’ve just noticed the laptop being real slow no matter what I’m doing on it. Other then that I haven’t seen any other problems.
