Hello,
I am having a problem very similar to what Mantis_51 had. Malwarebytes is alerting me about fff5ee.com being blocked, IP address 95.215.1.57 mainly, and it's also the same file location as him that's affected, SysWOW64/dllhost.exe. Only difference is, how I came to this point. My computer seemed to be running okay when I wasn't browsing. My issues were mainly with the browser. I would get mysterious messages about security settings blocking a download when I wasn't trying to download anything, and for awhile, I'd be getting COM surrogate errors. Those seemed to die down. Then two days ago, I got an alert from my ISP that I was 99% for the month for my data usage (250 GB). That got me, as I usually don't even come within 50% of it. I managed to get to 112 GB in a month during a Netflix binge, and in this case, I managed to do it in two weeks without having much time for movies. I opened my resource monitor, and noticed a ton of dllhost.exe files running, and no idea what they were doing there. I opened Malwarebytes, realized I hadn't updated it in awhile (got really busy over the last couple months and a lot of things got forgotten), and after that, the dllhost.exe processes went away and so did the errors, but then came the popup alerts. Malwarebytes came up with a couple of trojans during an overdue scan i ran, both tagged to msiexec.exe, but like an idiot, without thinking, I deleted the quarantines without taking a close look at what they were, other than being a trojan. Googled the problem and found out about Poweliks, found Mantis_51's thread, and here I am now. Avast is my antivirus software, in case you're wondering. I suspect that I'm probably going to end up wiping the drive, but would like to open a dialogue with you about this, just in case it's not what I fear. Would like you to walk me through this step by step, as I've never had a virus hit me before at all, so even though I could just copy what you've had others do and will most likely have me do, would prefer not to do anything without your instructions. Thanks!
Dave
