A. B. C. D.A.
If Joe is experiencing the same symptoms that were present prior to the virus removal, then it's likely that the original repair wasn't successful. To prevent this from happening again, the technician should have covered the following as part of the original repair:
A. End-user education: The technician should have provided Joe with some education on how to avoid getting viruses in the future. This could include things like being careful when opening email attachments, avoiding suspicious websites, and keeping antivirus software up to date.
B. Pre-installation environment cleaning: The technician should have cleaned the computer's pre-installation environment, which includes the BIOS, Master Boot Record, and any other firmware or software that runs before the operating system. This is important because some viruses can hide in these areas and survive a regular virus scan.
C. Disabling of System Restore: The technician may have disabled System Restore to remove any infected restore points. This is done to prevent the system from being infected again if a restore point containing the virus is used.
D. Infected system quarantine: The technician should have quarantined any infected files or programs to prevent them from spreading to other parts of the system. This may have involved deleting the infected files or moving them to a separate location on the system where they can't harm other files.
If the technician didn't cover one or more of these steps, then the virus may not have been fully removed, leading to the return of symptoms.
