What is the best anti-malware solution ? What about PC Doctor ?
There is no simple "best." Note that a single such program is not good
enough to protect you. Note what Eric Howes, who has done extensive
testing on Anti-Spyware products, states:
"No single anti-spyware scanner removes everything. Even the
best-performing anti-spyware scanner in these tests missed fully one
quarter of the "critical" files and Registry entries" See

So given that a single product is not enough for good protection, two
are better than one, three are better than two, and so on.
Do you "need" more than two? There's no clear answer to those
questions. My own practice is very conservative, and I
personally run
Spybot Search and Destroy
Adaware
Spyware Blaster
Windows Defender
Super-Antispyware
A-Squared
but not at the same time.
Also, routers with firewalls, what can they do, which one is best ?
They can prevent intrusions, and they are all good at it.
