  1. Last night AVG poped up saying virus detected. I was on internet explorer at the time. A little window popped up that I had never seen before. The computer automatically restarted. So I did a system scan with AVG and it found 2 viruses in Windows, Trojan horse IRC/Backdoor.SdBot.OIR and Trojan Horse Proxy. (something). They were deleted and everything seemed to be ok. Now everything is screwed up (there are about 20 bogus processes in the task manager.) Any suggestions?

    HJT alone will not overcome viruses and other stuff. if you want to do this yourself...

    download, install, and update AVG free edition. (free.grisoft.com) do not run a scan.

    download, install ad-aware SE personal (http://www.lavasoftusa.com/software/adaware/). update definitions file dut do not run a scan.

    download, install ccleaner (http://www.majorgeeks.com/download4191.html), choose not to install the context options during setup)

    download, install ewido security suite (http://www.ewido.net/en/) uncheck "Install background guard" and "Install scan via context menu" during installation.

    reboot your computer into safe mode by pressing F8 repeatdley during the boot process until you get a menu. use your arrow keys to select safe mode and hit enter. log into windows as "administrator", not your normal user account.

    run a full system scan in AVG antivirus.

    reboot your computer into safe mode by pressing F8 repeatdley during the boot process until you get a menu. use your arrow keys to select safe mode and hit enter. log into windows as "administrator", not your normal user account.

    reboot your computer into safe mode by pressing F8 repeatdley during the boot process until you get a menu. use your arrow keys to select safe mode and hit enter. log into windows as "administrator", not your normal user account.

    open ewido and run a complete system scan. when it finds its first problem, If Ewido finds anything, it will pop up a notification. You can select "clean" and check the boxes "Perform action with all infections" and "Create encrypted backup" before clicking on OK.

    open ccleaner, and run the operation "run cleaner" in corner

    reboot your computer, letting it boot normally and log into your user account. download mozilla firefox (www.mozilla.org) and make it your default browser. when you use the internet, use firefox instead of IE to do so.

    these operations usually take out more than 98% of your problems. run hijackthis, save a logfile, and post it here.
