View Full Version : Chrome riddled with adware and persistent extensions

Hi, guys... My girlfriend handed me her friend's laptop so I could try and see what's wrong with it. I ran MBAM and AdwCleaner, both of them found thousands of stuff and I applied the fixes offered by both programs.

Most of the adware seem to be now gone, but at least two occurences still persist on Chrome: when I check the extensions tab, I get ShopDrop and UTubeNoAdsa, as in the following screen capture:

I still don't know what ShopDrop does exactly, but even if I remove it, it'll be back next time I start Chrome. As for the other one, I can't remove it at all due to that weird "Installed by enterprise policy", and it's the one giving me more trouble. Thanks to that extension, every website I access, even this forum, is filled with ads everywere.

Hope you guys can help me...

As instructed, I've already backed up my registry using ERUNT and produced the DDS and aswMBR logs. Additionally, as I've seen from another thread with someone suffering from the same ShopDrop problem, I'll also attach the OTL log.

Thanks in advance for the help!
