To report your problem accurately, it is best not to rely on your memory. Be as specific as possible.
Some computer viruses can take time to reveal themselves.
Record any unusal messages that are randomly displayed even if they don't seem to affect the performance of your workstation. Record how you became aware of the problem. Record what you were doing before the event occurred. Identify any removable diskettes that may have been used during this period. Any data you have saved can potentially have been infected by the virus.
