After cleaning out my computer somewhat, I told my mom about a malware program I had. She said she had been having a problem with her computer as well, but doesn't know exactly when it started. Everything seemed fine but after a few minutes the computer almost froze completely. When I finally got task manager up I saw a program running, AcroRd32.exe, and it was using a lot of memory.

I always understood AcroRd32.exe to be acrobat reader, but never had that kind of problem before. When I closed it her computer was fine, but it eventually came up again. I read that it could be a virus if it's in the Windows or System32 folder, but I can't seem to find it. I ran a virus scan and nothing came up. How can I find out if this is a virus?

Most of the processes in Task Manager will be legitimate as shown in these links.Determining whether a file is malware or a legitimate process usually depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file like svchost.exe. However, it then places itself in a different location (folder) than where the legitimate file resides and runs from there. Another techinique is for the process to alter the registry and add itself as a Startup program (AcroRD32.exe: Added by the Troj/Dloadr-BDK Trojan) or service so that it can run automatically each time the computer is booted. Keep in mind that a legitmate file can also be infected by some types of malware such as Virut which is a dangerous polymorphic file infector. A file's properties may give a clue to identifying it. Right-click on the file, choose Properties and examine the General and Version tabs.

Tools to investigate running processes and gather additional information to identify them and resolve problems:These tools will provide information about each process, CPU usage, file description and its path location.

Anytime you come across a suspicious file or one that you do not recognize, search the name using Google <- click here for an example.

Or search the following databases:If you cannot find any information, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
