Yesterday, I got an error message while I was simply browsing a site (normal site, not suspious). The message was "DWWIN.exe application failed to initiate properly". The PC then basically started to "die"- anytime I tried to open an application, I received the message "application or DLL C:'properties\mozillafirefox\xul.dll is not a valid windows image. Please check against your installation disk". That is just an example of what happened when I tried to reopen firefox. If I tried to open say, microsoft word, I got a similar message that a dll file was not valid or that there was not enough system resources (I do have sufficient hard disk space so that is not the issue).
Since yesterday I did not have access to another computer to get on this board, I decided to try to run Malwarebytes (which came back clean). I also scanned with avast, which came back clean. Since I had experience running combofix for my other problem years ago, I tried to run it to see if it would help. It went through all the stages and then stalled saying "insufficient resources". It just sat there for a very long time and did not respond, so I eventually rebooted and then used the computer normally for several hours last night and all day today. Everything seemed fine until a few mintues ago, when the same issue popped up. This time, it was not DWWin.exe, but I am simply getting error messages that applications fail to initiate, etc.
The only thing that I have installed recently is just the normal AVAST update (received an AVAST message that I needed to update). That update proceeded normally a couple of days ago with no apparent issues. The other issue I noticed is that I tried to save a file and got a message saying that I needed permission from the administrator (no adminstrator but me). So unclear what has taken over my system.
Now that I have access to another laptop and can access this board while my desktop is having problems, I am more than happy to let one of you take control. Any help is greatly appreciated.
PS, I have noticed that my start button does not have the word "start" anymore and many of my icons have lost their color, etc. This makes me think something has definitely taken over.
