antivirus/malware/firewall

ok.. i just got rid of the virus bankerfox and win 32 with the help of
sneajyone... sensationjal bloke and he needs a medal.. but at this point
i still havent got an antivirus running and i assume that i have the
basic firewall from microsoft on... i don't have a very good laptop its
about 4years old and it doesnt have loads of memory... what do u
recomend that i put onto it in those departments above....
Well, on this particular computer I do not recommend to run a third
party firewall. Windows firewall is pretty decent and takes up less
resources than third party firewalls.

For your antivirus I recommend Panda Cloud Antivirus - it is the lightest of the free antivirus. Install it without the toolbars.

A second choice of antivirus would be Avira.

Besides an antivirus you should install an on-demand scanner.
MBAM is the recommended choice. Use it to periodically scan your system.

WinPatrol
alerts you when changes are made in vital system areas. Very light
program, especially good on light systems not running a third party
firewall.

Finally: browse safely. Google Chrome is the safest
browser imo. Mozilla Firefox with the NoScript addon is also very safe,
but Noscript has a couple of major disadvantages (it blocks legit
content and if you decide to "temporary allow" stuff on bad sites, you
open the door for infections).
