PCoptimizer 2010 is a rogue security program that pretends
to analyze your computer for virus infections and system errors. When installed,
PCoptimizer 2010 will issue an alert that states that one of your running processes
is a security issue and will then prompt you to clean your computer. Regardless
of what you press on the alert you will be brought to a screen where PrivacyGuard
will pretend to scan your computer for viruses and other system errors. When
finished it will state that it has fixed these errors and viruses, but that
there are other issues it could not fix until you license, or purchase, the
program. This is obviously a scam and you should not purchase the program regardless
of what it tells you.
