Do you use any spyware protection at all? Spyware can also cause a lot of strange things. As far as viruses, you could get a second on third opinion with free online scans here.
Recently we have had serious computer malfunction problems in the company I work with. It starts with Windows programs such as the Windows Explorer, or the Control Panel etc. giving the "Program not responding" message and the user having to end the program. Applications run much slower than expected. Also there are problems connected with hardware such as certain keys of the keyboard not always responding, "memory cannot be read" messages and generally devices not working as expected. The company is protected by MacAffee which is updated regularly and the scan did not find a virus.
It's critical for me to find a solution.
How can I be sure it IS a virus?
And what steps should I take from there, since the
virus scan comes up with nothing?
If anyone can help please do.
