If you find a virus

On a PC

If the virus is on a hard disk or in the memory of a PC, under no circumstances use the PC again until the virus has been eliminated. Unless you are responsible for the PC and are going to eliminate the virus immediately, switch off the PC. If the virus is on a PC in the University please report the problem to your department's Data Protection Advisors, PC support staff, or whoever is responsible for the PC. If the virus is on a shared PC please put a note on it to warn others. The virus may have infected floppy disks used in the PC so check these also (do not use an infected PC to check floppy disks). If the virus is in software obtained over a network please inform the person responsible for that network filestore.

On a USB flash drive

If the virus is on a flash drive do not use the device again until the virus has been eliminated. PCs in which the infected drive has been used may be infected so check these PCs or notify the people responsible for them. If the flash drive was given to you by somebody else then inform them.

On a CD

If the virus is on a read-only CD you will not be able to eliminate it yourself.  Label the CD to warn others of the infection and immediately notify the company or person who produced the CD.

On a network drive

If a virus is on a network drive shared by others please immediately report the problem to your Data Protection Advisors, PC support staff, or the person responsible for that network filestore (viruses on shared network drives are potentially very serious).

Eliminating viruses

Eliminating viruses is often straightforward, particularly if the virus is on floppy disk. Anti-virus software will automatically eliminate many viruses found by on-access or on-demand scanning.

If the Anti-virus software fails to eliminate the virus a special 'clean boot' procedure may be necessary.  This applies to the boot-sector type of virus.
