Hello, I'm not sure if I'm posting this in the right forum. My laptop seems to be laggy and runs hot, at times it's hotter than other times. It also runs loud, like it's working too hard or something. For example, if I am watching something, the video will be fine for a while and then it will become slow/laggy and so will the rest of the computer. Again, not sure if this is a virus issue, but I've had viruses in the past so I thought I'd start here and be redirected if necessary. Thanks!

Which "Operating System" is installed on your laptop?

Windows 7, Windows Vista or Windows XP?

If you have Windows 7 or Windows Vista; The internal RAM can be found at this way; Click on the right mouse button on "My computer". Click Properties. Now a screen will appear, on that screen your RAM is mentioned.

Normally 2 GB - 4 GB RAM is enough for a normal computer user, so I think we need to rule out viruses or malware:

Run a scan with MBAM:

Download the free version of Malwarebytes' Anti-Malware (aka MBAM): http://www.malwarebytes.org/products/malwarebytes_free to your desktop.

  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
  • If an update is found, it will download and install the latest version.
  • Once the program has loaded, select Perform quick scan, then click Scan.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, and click Remove Selected.
  • When completed, a log will open in Notepad.
  • Post the log back here.

Note: You will need to use Internet explorer for this scan - Vista and win 7 right click on IE shortcut and run as admin
Go to the Eset web page to run an online scanner from ESET.

  • Turn off the real time scanner of any existing antivirus program while performing the online scan
  • click on the ESET Online Scanner button
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the ActiveX control to install
  • Click Start
  • Make sure that the option Remove found threats is unticked and the Scan Archives option is ticked.
  • Click on Advanced Settings, ensure the options
  • Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  • Click Scan
  • Wait for the scan to finish
  • Click on copy to clipboard or copy and paste the results here in this topic

There are some files that needed to be deleted because they are infected:

delfile.bat
Open Notepad and past the content of this code into it;

@echo off
del /f /s /q "C:\Users\Owner\AppData\Local\Apple Computer\Apple\fprpbuai.dll"
del /f /s /q "C:\Users\Owner\AppData\Local\Apps\Apple Computer\fqdjghtun.dll"
del /f /s /q "C:\Users\Owner\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\6LFOJTQK\FreeFileViewer2011Setup[1].exe"
del /f /s /q "C:\Documents and Settings\Owner\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\6LFOJTQK\FreeFileViewer2011Setup[1].exe"
del /f /s /q "C:\Program Files\RealArcade\Installer\bin\OCSetupHlp.dll"
del /f /s /q "C:\Program Files\RealArcade\Installer\bin\OCSetupHlp.dll"
del /f /s /q "C:\Documents and Settings\Owner\AppData\Local\Apple Computer\Apple\fprpbuai.dll"
del /f /s /q "C:\Documents and Settings\Owner\AppData\Local\Apps\Apple Computer\fqdjghtun.dll"
del %0

  • Save the Notepad file on your desktop as delfile.bat. Save type as "All Files".
  • Double click on delfile.bat to execute it.
  • A black CMD window will flash, then disappear, this is normal.
  • The files, if found will have been deleted and the "delfile.bat" file will also be deleted.

Have you perform a defragmentation of the hard-drive?

If not perform one (Shortest way to this: Start > into the searchbox enter dfrgui. Click on it.

Then chose for "Defragment disk"

Is there any improvement?

If you don't see any improvement, perform a snapshot with Speccy - http://www.bleepingcomputer.com/forums/topic323892.html/page__p__1797792#entry1797792

I think there might be some improvement, it's hard to tell. Take a screen shot of what?

I ran the EST scan again and it found another threat:

I don't mean to but in but with laptops major heat issues can also be from dust packed into your fan. If you have or can purchase a can of compressed air see ho much dust comes out of your fan by blowing through your vents.
