Anti-Virus, Anti-SpyWare and firewalls are all important, both at work and at home. I can discuss your security requirements and help you choose Anti-Virus, Anti-SpyWare and firewall software.
I can also help you develop company policies on the use of PC's and the Internet.
There are other software products that will allow you to "lock down" your PC's so as floppy disks can't be used without authorisation, software can't be installed without authorisation and potentially dangerous downloads from the Internet can be stopped before they damage your PC or network.
It's also very important that e-mail is checked for viruses. Some ISP's will virus check your e-mail before it gets to you, they can also check for spam and pornography.
