Hello. thank you in advance for any help you can give. I have scanned using spybotSD, many trojans are detected and malware, only one cannot be removed; FraudXPAntiVirus malware (5 entries, 1 cannot be removed). Upon restart all the problems come back. error messages which dont close Invalid floating point errors updates disabled on antivirus/spyware/windows Disabled security centre Desktop background taken over with warning message system tray warning messages task manager disabled web pages redirected. It all happened at once! Attached is my HijackThis log file; Many thanks.
