I had the same problem that others have recently described, with each new site opened in the browser (Chrome) eliciting the “Malicious URL Blocked” pop-up message, so I ran all the initial scans detailed in the instructions provided, and will attach those logs here. The message actually stopped happening after the reboot required by the first tool (AdwCleaner), but even so, I am now very worried about what may still be lurking, mostly because I use this beast for online banking… in addition to my job and everything else. The Malwarebytes quick scan came up with four problems that it was then able to successfully remove… Not sure if that’s pertinent info, but there it be. If someone on here can take a gander at the attached logs and let me know what, if anything, still needs to be done, I’d really appreciate it… Thanks.
hey and welcome to the forum. and thanks for attaching the necessary logs i will drop a note to one of our malware expert here on the forum on your thread.

Restart your computer. How is your computer running now?
Hi, thanks for getting back to me… I re-ran the OTL scan with the text you provided in the box and have attached the report here. I also downloaded the AT-Destroyer and ran it as instructed. That log report is also attached. I saw one red line in the report, with the rest being green, but I have no idea what it said, as my Spanish is lacking to say the least. Aside from all my Google Chrome settings being reset (which I’m assuming was by design), the computer seems to be working fine… But it was pretty much working fine before that. I had just been getting the “Malicious URL Blocked” notice, but even that went away after the initial AdwCleaner scan. I did however start getting a semi-regular pop up from Malwarebytes saying that a malicious site was being blocked, but I’m not seeing that now. I’m just really concerned about my banking stuff and passwords, and whether or not I’ll be able to change them from this computer, so let me know what these log reports are telling you and what else, if anything I need to do.

Yes, it was by design. From the log I see what the AT-Destrojer done. That’s why I’m looking for feedback with logs.
I always know the current state of the system and I know what specific tools did…
I'm just really concerned about my banking stuff and passwords, and whether or not I'll be able to change them from this computer, so let me know...When we finished case I'll tell you whether there is a need for it. Of course it is advised to do.

How’s your computer running now?
Here is the last OTL report you requested. Computer still seems to be running fine… possibly even a tad quicker opening programs/sites (hard to tell, as it was already fairly quick).
…Awaiting further instructions.
Logs also looks clean.
You did not have any kind of malware that is known to steal any data.
Anyway, if you do any banking or other financial transactions on the PC, it is always desirable to change the important password just for precaution.
We will remove used tool.
Re-run OTL and click on CleanUp! button.
You will be asked to reboot the machine to finish the cleanup process, choose Yes.
After the reboot all the tools we used should be gone.
Note: Some more recently created tools may not yet be removed by OTL. Feel free to manually delete any tools it leaves behind.
Everything seems to be a-ok… Thanks for all your help.
