Hello, and thank you in advance for your help.
A few months ago, my system became infected: namely, AntiMalware Doctor and the Google redirect virus. After getting some help from Microsoft Customer Support, I found your forums. Since then, I have received lots of help from Malware Response Team member Sempai. I'm happy to say the infections appear to be gone; however, some issues seem to persist.
Audio & video is choppy and stuttered. This occurs with all audio and video, from my own music and videos on my HD to youtube and other streaming video to games run through flash, java, etc. The only site that doesn't seem to be choppy is Hulu. For some reason, their video comes through with no issue. My main issue is with SlingPlayer, an application that uses my SlingBox (a device hooked to my cable box that allows me to stream my television online) that worked with no problems before. Now, it is unwatchable, due to the extreme stuttering. I have tried letting it buffer, but no amount of storing up the video seems to matter. Also, youtube and other streaming videos tend to run a little better once I have let them completely load, but it doesn't always work and it isn't perfect.
Whenever I Restart my computer, the audio controls on my machine stop working, and the Volume icon on my system tray disappears. I effectively have no volume control. The only remedy for this that I've been able to figure out has been using System Restore to go back a day or so. Then, it works fine until I have to restart again.
Last night, after attempting some fixes that the Malware Response Team member suggested, something happened to my video. Most of the icons on my system disappeared: desktop icons, sytem tray, files and folders, even the windows logo on the start button. Along with that, when I attempted to shut down Avast Antivirus in order to run ComboFix, the screen would go gray, as it should, but no popup window was visible. The popup window is necessary to verify that I requested the deactivation of the antivirus. After some tabbing and spacing, I finally got it to work. After a few minutes, I got a blue screen and a restart. This happened several times. I finally did another restore this morning after being redirected here from the Malware Response Team.
Here is a link to my original post: http://www.bleepingcomputer.com/forums/topic394668.html
I am on a Compaq Presario M2000 notebook, model M2305NR, running WinXP Pro. It came with XP Home, but at some point, the previous owner (my grandfather) had someone put XP Pro on it. I have an XP Pro CD, but I am unsure if it has SP3 on it, and I don't know how to check. If you need any more info or specs, don't hesitate to ask.
Thank you again for all your help.
