My computer is infected with the W32.Pinifi virus, and my antivirus
software is not helping.  What can I do to solve this problem?

Hello dm1906,

Great question. I think the actual virus (trojan) that you are
referring to is called 'W32.Pinfi' (vice Pinifi). Some of the aliases
for this infection can be found here :

TrendMicro Virus Database
http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=PE_PARITE.B

On the above page it states that their free online virus scan will
remove this from your computer :

Housecall Free Online Virus Scan

There is another tool available that will assist you in removing this
trojan as well, should you find the first one does not meet your needs
:

Panda Software (click on Prevention and Cure)

Please let me know how it works out for you. If you are discontent
with your current AntiVirus program, may I recommend this free
software that has saved me countless hours on numerous occasions. It's
free and comes with an email scanner as well :

AVG AntiVirus (Free Version)

To assist with this answer I searched Google for :

Thanks again for the question. Should you need further clarification
or assistance, please ask. I will do all I can to assist.
