Some comments:

I haven't been able to re-update it (or Media Player, nor play DVD's) since my computer got infected and blue-screened and I had it repaired / corrupted Windows files replaced, etc. This happened a pretty long time ago and is a separate issue.

My computer was recently infected, and since I removed a ton of stuff both manually and with HJT and Malware-Bytes and got rid of the typical "trojan lag" everything has been fine, except that my computer periodically experiences what I term as "crunchy lag" which impacts EVERYTHING. For example if I were just sitting on my desktop with nothing open, moving the cursor around, and this started, the cursor would "skip" around the screen; if I were watching a video the video would skip, jitter, etc. and then perhaps fast-forward to get to where it would've been otherwise, depending on what means I'm using to watch it. At the same time that it doesn't seem like a hardware issue, it does, as when I watch a video on say YouTube and something relatively graphic-intensive happens, it seems to aggravate the problem; although if I replay a part like that it usually won't lag there again.

My primary concern here is that somehow a hardware issue arose from this infection; the infection was the desktop-background-stealing, false security warning left-and-right kind. I think the most specific reference I saw in scan results was that really notorious one that starts with a Z and is kind of short, like "Zlob" or something -- but I'm probably off on the name. The infection "process" lasted ~3 minutes and scan results made it pretty clear to me that a lot of stuff had been loaded onto my computer. I probably should've just cut the power but I wasn't thinking clearly. My computer was on that night when I slept and when I used it the next day Windows had apparently killed itself temporarily to prevent something really bad from happening, 'cause I got that message. I did a more thorough scan with MB and there were like 5 things (1/4th the amount as before, at least) that I missed before, basically the same stuff.

I'm curious as to why there are 3 svchost.exe's yet 8 listed in Task Manager. Probably nothing, as I know that many instances of this isn't necessarily a bad thing, but I also know that viruses or whatever sometimes imitate this file.

Third, the only registry item that seems dubious here is the first one. In my experience with HJT if the information of the item won't appear, that's usually the first indicator that the item is screwy. Prior to referring to userinit.exe it referred to an .exe that was bad that came as a result of this last infection; prior to THAT I'm pretty sure it referred to userinit.exe, but I'm also pretty sure that even way back then I couldn't get the info box on its F2 classification to appear (which per se isn't a problem, just creates questions).

So anyway, how does the log look:

http://img502.imageshack.us/i/vvrs.jpg/ -- Here it is again listed as hidden service, which I found with rootkit scanner GMER. I was unable to remove it with GMER.

Any help appreciated. Thanks for your time.

Okay, so the first picture in my last post shows a scan result with SUPERAntispyware with trojan and reference to "asc3550p." Second picture shows scan result with GMER rootkit scanner and it shows clearly asc3550p HIDDEN service. I read up on svchost.exe, and they're like bundles of your running services. I ran command tasklist /svc and in the third instance of svchost there appears 2 services that I did not see in a picture of this list under the 3rd instance of svchost (the one with the most services) from some other person's computer, and they are "SharedAccess" and "HidServ." I think it's safe to say that the latter one stands for Hide Service and probably has to do with this trojan thing. I was going to post a picture but I keep experiencing weird problems like hang ups / lag when I do things on Web sites . . . there is definitely extraneous processing that occurs regularly . . . I can only hope that it has to do with this and is not hardware related. Checking services in administrative tools just now, I also don't see anything like "Shared Access."



While we understand your frustration at having to wait, please note that Bleeping Computer deals with several hundred requests for assistance such as yours on a daily basis. As a result, our backlog is quite large as are other comparable sites that help others with malware issues. Although our HJT Team members work on hundreds of requests each day, they are all volunteers who work logs when they can and are able to do so. No one is paid by Bleeping Computer for their assistance to our members.

Further, our malware removal staff is comprised of team members with various levels of skill and expertise to deal with thousands of malware variants, some more complex than others. Although we try to take DDS/HJT logs in order (starting with the oldest), it is often the skill level of the particular helper and sometimes the operating system that dictates which logs get selected first. Some infections are more complicated than others and require a higher skill level to remove. Without that skill level attempted removal could result in disastrous results. In other instances, the helper may not be familiar with the operating system that you are using, since they use another. In either case, neither of us want someone to assist you who is not familiar with your issue and attempt to fix it.

We ask that once you have posted your log and are waiting, please DO NOT "bump" your thread or make further replies until it has been responded to by a member of the Malware Response Team. The reason we ask this or do not respond to your requests is because that would remove you from the active queue that Techs and Staff have access to. The malware staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response, there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

That is why I have made an edit to your last post, instead of a reply. Please do not multiple post here, as that only pushes you further down the queue and causes confusion to the staff.

Please be patient. It may take several days, up to more than a week, perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

Thank you for understanding.

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

Please include a clear description of the problems you're having, along with any steps you may have performed so far.

Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process.

Even if you have already provided information about your PC, we need a new log to see what has changed since you originally posted your problem.
[We need to create an OTL Report
  1. Please download OTL from one of the following mirrors:
  2. Save it to your desktop.
  3. Double click on the icon on your desktop.
  4. Click the "Scan All Users" checkbox.
  5. In the custom scan box paste the following:
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\*. /mp /s
  6. Push the button.
  7. Two reports will open, copy and paste them in a reply here:
    • OTL.txt <-- Will be opened
    • Extra.txt<--Will be minimized

In the upper right hand corner of the topic you will see a button called Options. If you click on this in the drop-down menu you can choose Track this topic. I suggest you do this and select Immediate E-Mail notification and click on Proceed. This way you will be advised when we respond to your topic and facilitate the cleaning of your machine.

After 5 days if a topic is not replied to we assume it has been abandoned and it is closed.
