When I tried to update Windows XP Home with SP3 i may have got a virus.I have a corrupted task manager that does not display fully and can no longer access the internet.I have run several scans using Avast,SPbt,Mwbts and SAS-not to mention dr web cureit.All indicate i have no virus.I have been unable to operate in safe mode but have been advised how to access this on another forum.I believe I should be altering the registry bbut would welcome some guidance Many thanks John
