Most virus intrusions come through "social engineering"
Like opening email attachments or clocking on malicious links.
Prudence and adequate external backup is your best defense.
I find that the free Microsoft security essentials does the job.
It updates with windows update and is unobtrusive.
Isn't MSE a terrible product like many people said?
I think not.
The fancy testers are testing how well a virus in the wild can be detected.
That is nice, but that is not common.
MS is gathering reports of infections and is trying to protect against the frequently found ones.
Regardless of what antivirus or malware checker you use, you must protect yourself against the possibility of infection.
It can happen to anyone. A trusted web site could run a malicious ad, for example.
Backup externally whatever you value.
Clone a "C" drive to recover your OS and your apps. Keep that offline.
If anything, MSE is free, easy to use, scans fast and is updated easily.
