I think my laptop (Windows 7 64 bit) may be infected.  I cannot install programs such as Temporary File Cleaner, DDS, TN PageDefrag.  I receive an error: "Error writing temporary file. Make sure your temp folder is valid."


I have checked using Windows explorer, and both the C:\Users\[user name]\AppData and C:\Windows\Temp folder exist.  They may have been corrupted, but they are there.


Also, according to the Windows Action Center (in Control Panel), my antivirus program (McAfee) is turned off.  However, when I open McAfee, it says it is turned on.  Please see attached screenshots.  Is Windows not recognizing my antivirus software? I am vulnerable to (further) infection?


I do not know how to clean my PC and possibly rid it of any malware, since I cannot install these programs.

Please help!

It is possible that what ever infected your machine, may have hidden those folders.  You can try a Repair of Windows 7.  See the following.  http://www.sevenforums.com/tutorials/3413-repair-install.html  If all you have is the System Recovery DVD's, that you made that are specific to your machine, the link I posted, gives you a valid link to download a .iso, to help you do a repair of Windows 7.

Thanks for the response, Greg.


Unfortunately, I do not have the Windows 7 system install/recovery CD.  This laptop is~3 yrs old, I no longer have the disc (if it even came with one from Dell).


I have tried using System Restore, but I received an error stating that the system "failed to restore".


Most programs will not install, they give an error stating my temp folder is invalid or missing.


Re-installing or repair-installing Windows seems a little extreme, and I don't even know if I'd be able to re-install or re-activate a legitimate copy of Windows without my factory disc. Any other scanners or repair programs I could try first?
