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.
