BleepingComputer.com: ??not quite sure??

Just curious....About a month a go someone hacked my yahoo and changed all my info. I also had Myspace IM and when I would open it... my screen would go CRAZY!!!(my icons would get big and everything would be different colors...so I uninstalled it) I am not sure of their intentions other than to annoy me. Since then my computer has frozen up a few times and had to be restarted. I don't think I should be having issues with freezing and such considering I just got the laptop for Christmas. Also, I was looking through my startup programs and there are a couple suspicious programs on there....there are NO Publishers and they are not Digitally Signed
Name: N/A
File Name: AOLDDI. LNK


Name:N/A
File Name:RGSCLauncher.exe/silent

Name:VAIO MyMemCenter
File Name:VAIO MyMemCenter.exe

Then...
AutoLaunch WLASU, Welcome Launcher, and Java are not signed...


Thank you in advance for any help!!!

Most of the processes in Task Manager will be legitimate as shown in these links.

Anytime you come across a suspicious file or one that you do not recognize, search the name using Google or the following databases:

• BC's Startup Programs Database
  
• SystemLookup StartupList Index
  
• File Research Center
  
• ProcessLibrary.com

Determining whether a file is malware or a legitimate process sometimes 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. However, it then places itself in a different location on your computer. Another techinique is for the process to alter the registry and add itself as a Startup program so that it can run automatically each time the computer is booted. 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:

• AnVir TaskManager Free
  
• Process Explorer
  
• System Explorer
  
• ProcessHacker
  
• Process Monitor
  
• svchostViewer

These tools will provide information about each process, CPU usage, file description and its path location If you right-click on a file and select properties, you will see more details.

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.
-- Then post back with the results of the file analysis.

Thank you...I will try these and see what comes of it.

You're welcome.
