I keep recieving emails from my internat service provider (Optus) warning me that I may have malware and my computer could be a zombie Ther is no obvious performance or useage problems with any of computers
I ran stopzilla a free virus program and it deletede a few cookies but this warning keeps comming
I just down loaded Spy Hunter 4 and it found 7 possible problem but thay all apear to be tracking cookies and I doubt if the $39 required to register to then delet them is worth it. (also it has replaced my home page with its page which also leads me to not want to register)
the Network has 4 computers but I'm fairly sure this warning is caused by just one computer as other one are all very slow or usually off.
Can you offer any advice or recomend a reputable program fpr detecting /deleting malware?
I have copied typical warning email below

What you should do
The best way to prevent your computer being infected is to use anti-virus
software and a firewall, and keep security patches up-to-date. You may also
wish to consider anti-spyware software and a spam filter.
If you are already using anti-virus software, we recommend you update your
virus scanning software then scan your system to detect & remove any virus
you may have.
If you do not have a virus scanner there are many companies which offer
software that can be downloaded or trialled from the Internet. More
