I'm new to this; I followed the intructions in Self-Help, and have run ATF Cleaner but I'm still having problems. For example, I keep getting popups from SystemErrorFixer.com including ads from various websites such as: wallst.com, fubar.com,etc. On startup, I'm also getting a message that says: Error loading C:\DOCUME~1\Guest\LOCALS~1\Temp\yxplnej.dll

Sometimes I'll also get this:

Buffer overrun detected!
Program C:\Program Files\Internet Explorer\Iexplore.exe
A bufer overrun has been detected which has corrupted the program's internal state. The program cannot safely continue execution and must now be terminated".

I appreciate any help. Thank you.

Here's my log:

Hi miyashu,

Please download ComboFix to your desktop
  • Double click combofix.exe and follow the prompts
  • Note: Do not click ComboFix's window while it's running - it may cause it to stall!
  • If after ComboFix finishes you do not have internet access, then reboot your computer to restore it
  • When finished, it shall produce a log for you, please post it in your next response

Now open HijackThis, select Open the Misc Tools section
Press the Open Uninstall Manager… button, then press Save list…
Save the Uninstall log to your Desktop and include a copy in your next response.
Now press Back and Scan and then Save log to create and save a new HijackThis log.

Once complete, please post the ComboFix report, the uninstall list and a new Hijackthis log.
