Have you tried to run your antivirus in safe mode? You can boot into safe mode by tapping the F8
key as soon as you start your computer. You will be brought to a menu where you can choose to boot into safe mode. Make sure you choose the option without networking support. If you know the exact location of the files, you should be able to delete them manually in safe mode. By the way, what are the "options" that the antivirus gives you? Does it give you an option to delete the files or send them to quarantine, if so either of those options should remove the files. The server.vbs is related to Sony for sure. but don't know about the second file. According to the file database here at bleeping computer, "server.vbs is part of Sony's Vaio support agent - designed by Support.com. Not required if the user does not wish to use the Vaio support agent and regarded as spyware".
If you have no luck with the antivirus in safe mode, or you cannot delete the file manually, I suggest you try ewido antimalware.
Please download, install, and update Ewido anti-spyware
Load Ewido and then click the Update tab at the top.
Under Manual Update click Start update
After the update finishes (the status bar at the bottom will display "Update successful")
Then click on the Scanner
tab at the top.
Click the "Settings" tab and then change the recommended action to Quarantine
Click Automatically generate report after every scan
Click back to the "Scan" tab and then click on Complete System Scan
This scan can take quite a while to run, so be prepared.
Ewido will list any infections found on the left hand side.
When the scan has finished, it will automatically set the recommended action.
Click the Apply all actions
Ewido will display "All actions have been applied" on the right hand side.
Click on "Save Report", then "Save Report As".
This will create a text file. Make sure you know where to find this file again (like on the Desktop).
Close Ewido and reboot!!
Let me know how it goes.
