This is a post transferred from Windows 7 on recommendation of moderator.
One computer on a Lan of 7 uses up 10 times the bandwidth the other 6 use, even when the computer itself is not being used, but is turned on. Computer is Dell, i3 processor; 4 gb ram, 500 gb hard drive, about 100 gb used.
Have not been able to discover the offending file. Adaware Malbytes will not run on computer. DDS.com won't run. Combofix won't run. Whenever a diagnostic program is downloaded, the computer refuses to allow the download to complete, calling the program a "virus" and deleting it.
Trying to use safe mode, did not get beyond looking for a restore point because computer simply ran an activity indicator without doing anything. Checkdisk started running, got to 67% complete, deleted a list of index files, and stopped at 67% complete. Keyboard will no longer input anything. No mouse.
Called Dell, they said that if we reinstalled the operating system, Windows 7 Pro, the data would not be affected on drive C: but not sure we want anything left of former data on the computer after we reinstall, thinking that virus could still be on.
Is it true that if we attempted to reinstall Windows 7 pro, all data files would be unaffected?
Have Carbonite installed; but it will not update files now.
Can't figure out where we are; control of diagnostic or repair programs seems to be removed from user.
Thought we could reinstall system, and the hard drive would be re-formatted as a result, thus destroying all old data, which we are willing to do if we can destroy whatever is causing this behavior on the computer.
Would that work?
