I see XP is at SP2 when SP3 has been out for over a year. SP3 contained many security fixes and by now that issue with the HP AMD machines is one we know how to deal with. You held back and got hit with malware that may have done less damage but what may be interesting is why no SP3?
I also see a very outdated Ubuntu. Isn't it up to 10.x?
Try running 10.x Ubuntu from CD to see if you can save your files. OR the cheap fix of installing a new blank drive to install XP and Ubuntu fresh then add your old drive later to reclaim files that are not on your backup.
==> Here's my thought. System Restore was not a known method to repair that malware. You appear to have tried something new and it's done some deep damage to the OS. Next time, research how others are dealing with the malware.
My pc got infected with Microsoft security essential alert. It didn't open browser, MS word ..
I wanted to do system restore, but there wasn't any system restore point created. I checked yesterday there were many restore point exist. I restarted my pc in safe mode, the pc freezed.
When I double clicked on c: drive using ubuntu it asked for authentication(System policy preventing access..) I gave the right password it didn't open. This message is displayed "DBus error org.freedesktop.DBus.Error.NoReplly: Did not receive a reply." Previously I was able to access xp files using ubuntu and no authentication was asked.
Next, I tried running XP. The pc shows a black screen, it didn't even show the progress bar when xp loads.
Please help me out.
