Hi,

I have a domain workstation infected with "Security Master AV" and although I thought I had successfully removed it - IT'S BACK!!! :flowers:

The domain user that got the infection is setup as a 'Power User' but I logged on as (Domain) Administrator and ran the entire process listed here (http://www.bleepingcomputer.com/virus-removal/remove-security-master-av). The process appeared to be successful and when I logged back in as admin workstation looked clean.

HOWEVER - upon logging in as the ('infected') user "Security Master AV" was back/still there. Whaaaat??

I have now upgraded that user to an Administrator logged back in and am presently re-running the process under that user name.

Any other suggestions/reasons why this never worked the first time? :thumbsup:

Thanks,
Mark

I can't answer the question about why it didn't work the first time. Or how you possibly may have gotten 're-infected.

But take a look here: Remove Security Master AV (Uninstall Guide)

I used the Security Master AV uninstall guide yesterday (it seems great, so thanks for that), but one thing in it did not work for me: using the hostsperm.bat did as described, but it didn't delete the hosts file, which was firmly holding on to life and refused all attempts to change it from read-only or the delete it (via Run command, etc).

Luckily, I found a post elsewhere (can't find it again to give the URL) which explained how to delete the hosts file: I needed to right-click the file, select Properties / Security / Edit and add back "Users" as a valid group, with permission to delete etc (click Advanced).

It seems that Security Master AV had renamed or erased the "Users" group definition - the only one visible was called "Authenticated Users", which I mistook as another way of saying "Administrators", which it is not.

I hope this will help someone else.

Thanks again for the uninstall guide.
