Dangers of oasclnt
As this is a relatively common process that exists any system with McAfee software, it is common for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files may have the same name but be stored somewhere other than in a McAfee-related subdirectory of %ProgramFiles%. Other malware may use a name that appears similar to it but with slight differences in spelling or with appended digits. While there are currently no known viruses, Trojans, or adware applications that disguise themselves as this process, you should look out for the presence of this file in an incorrect location or with a slightly different name.

There will typically be no more than one instance of this process running at any given time. The presence of multiple instances may be indicative of a malware infection. Furthermore, if you do not have any McAfee software installed, the presence of this executable is a likely sign of infection.
