Malwarebytes found AnviSmartDefender PUP in the Registry

Recommended Posts


I haven't actually been having any issues with my system but every now and then I like to run a Malwarebytes scan just to see if finds anything, usually it doesn't. Anyway after running it today it said it had found the following 4 registry PUP issues, all belonging to AnviSmartDefender:

Registry Key: 3
PUP.Optional.AnviSmartDefender, HKU\S-1-5-21-4079224529-1850452133-1189164913-1001\SOFTWARE\MOZILLAPLUGINS\anvisoft.com/AdblockPlugin, No Action By User, 295, 840222, 1.0.27693, , ame, 
PUP.Optional.AnviSmartDefender, HKLM\SOFTWARE\WOW6432NODE\ANVISOFT\Anvi Smart Defender, No Action By User, 295, 840212, 1.0.27693, , ame, 

Registry Value: 1

These have all been Quarantined.

I'm just curious to know if anyone else knows anything about these and whether I should just delete them. It's strange because I thought Anvi Smart Defender was a legitimate anti virus software, and I also don't have Anvi Smart Defender installed on this PC and never have. 

I'm also using Windows 8.1 64 bit.

Thanks very much for reading and any help you can provide,

Hello again,

I've looked through one of my old registry backups with notepad++ and it looks like I may have had Smart Defender installed at some point. Under "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Anvisoft\Anvi Smart Defender" I can see a value for "C:\Program Files (x86)\Anvisoft\Anvi Smart Defender". I probably tried it out a few a years ago but forgot about it. It hasn't been installed for years and so those registry values were probably not removed when it was uninstalled. 

 I think I'll just go ahead and remove them.

Thanks for your help,

Please download the attached Fixlist.txt file to  the same folder where the Farbar tool is running from.
The location is listed in the 3rd line of the FRST.txt log you have submitted.

Run FRST and click Fix only once and wait.

The Computer will restart when the fix is completed.

It will create a log (Fixlog.txt) please post it to your reply.

Please post the Fixlog.txt and let me know what problem persists.
