Pretty sure your comment was pointed at my post. So how long have you been writing Windows software, supporting Windows users in small business and maintaining you own internal network? Ive been doing it for over 20 years.[SIZE=+0] [/SIZE]Avast provides anti-virus program that still supports Windows 2000.
My advice. Get good anti-virus program and leave bad advice with people who don't know jack.
I stated what works for me, if you dont trust your actions then depending on an AV program is the right thing for you to do. They cant get to your computer or network without you doing or not doing something to let them in.
