Thanks, I'm using MS security essentials now (Win 7) and as for XP, I have an XP machine also but this is the host OS. Yes, I'm aware of using MS security essentials for XP on this machine, but since XP support is going to come to an end in April 2014, (and XP is one of my favorite OS's, among others so I'd like to keep using them, hopefully until I'm dead
but serious) I'm addressing this problem (at least, for my needs/desires) in this manner:
I do go online on this PC, but what I do is I use virtualization (thru VMWare Player - guest OS of XP) to go online, since it has its own virtual HDD, so I believe this keeps my host OS free of accumulating malware (adware, spyware, etc) and I keep a fresh backup copy of this virtual machine so when/if this current copy of this XP guest's VHD gets infected, I'll just delete it and copy this backup XP guest onto the host, open it in VMWare Player, and presto! A fresh web surfer PC (all without disrupting the host's applications/files that I'm currently working on) without having to wipe the host HDD, reinstall XP/service packs, programs, etc.
