Two hard, and fast rules:1.
Antivirus providing real time protection.2.
Firewall running (preferably, anything besides Windows firewall, as it only provides inbound traffic protection, and not outbound traffic protection)
Running more than one, of either, can cause conflicts, possibly rendering both inoperable.
You can have as many Spyware/Malware Programs as you want, and your system resources can handle.
I use all of the same programs you're using, and have had no problems.
Once a month I run 3 online scans, just as a precaution:BitDefenderhttp://housecall.trendmicro.com/TrojanScan
Also, if you're using Internet Explorer (IE)
, I would suggest you use an alternate browser, for better security.
I use Firefox, because it's a more secure browser than IE, as it doesn't use ActiveX controls
, but Java
Also, if a security flaw is discovered (which doesn't happen often)
, it's usually fixed within a few days, as opposed to the months you have to wait for an IE security patch.
In most instances, you will find Firefox to be a faster browser than IE, especially if you employ pipelining.Firefox Web Browser - Pipelining
The reason it's faster is because Firefox doesn't come pre-loaded with a bunch of features you don't need.
You can run Firefox as lean, or as bloated as you want with the use of extensions, which allow you to customize it the way you
want it, not the way someone else thinks it should be.Enhancing Firefox with Browser ExtensionsExtensionsNOTE:
When adding extensions I'd advise adding one at a time, try it for a couple of days, and if no problems arise, add another.
Sometimes extensions have been known to cause problems, due to incompatibility's, or corrupt downloads.
If you install them one at a time, and test it, it's easier to troubleshoot if one starts causing problems.
You don't have to uninstall IE to use Firefox, or any other browser.
You can use as many browsers as you want, at the same time.
Sometimes I'll have IE, Firefox
, and Opera
all open at the same time.
In fact you can't get rid of IE, as you have to use it
to get Windows Updates.
You can find other alternative browsers here, under the Web Browsers
heading:Freeware Replacements For Common Commercial Apps
Try as many as you want, and see which you like best, as they're all free.
