No, there shouldn't be any conflict if malwarebytes and adaware are both

on-demand applications.

 

For Win XP the most dependable defenses are:

1. Do not work as Administrator; For day-to-day work routinely use a

Limited User Account (LUA).

2. Secure (Harden) your operating system.

3. Don't expose services to public networks.

4. Keep your operating (OS) system (and all software on it)updated/patched.

(Got SP3 yet?).

5. Reconsider the usage of IE and OE.

5a.Secure (Harden) Internet Explorer.

6. Review your installed 3rd party software applications/utilities; Remove

clutter, *including* 3rd party software personal (so-called) firewall

application (PFW) - the one which claims: "It can stop/control malicious

outbound traffic".

7. If on dial-up Internet connection, activate the build-in firewall and

configure Windows not to use TCP/IP as transport protocol for NetBIOS,

SMB and RPC, thus leaving TCP/UDP ports 135,137-139 and 445 (the most

exploited Windows networking weak point) closed.

7a.If on high-speed Internet connection use a router.

For the average homeuser it is suggested blocking both TCP and UDP ports

135 ~ 139 and 445 on the router and implement countermeasures against

DNSChanger. (Is the Firmware of your router up-todate?).

And (just in case) Wired Equivalent Privacy (WEP) has been superseded by

Wi-Fi Protected Access (WPA).

8. Routinely practice Safe-Hex.

 

Also, ensure you do:

a. Regularly back-up data/files.

b. Familiarize yourself with crash recovery tools and re-installing your

operating system (OS).

c. Utilize a good-quality real-time anti-virus application and some vital

system monitoring utilities/applications.

d. Keep abreast of the latest developments.

 

And finally:

Most computer magazines and/or (computer) specialized websites are *biased*

i.e. heavily weighted towards the (advertisement) dollar almighty!

Therefore:

a. Be cautious selecting software applications touted in publications

relying on advertisement revenue.

b. Do take their *test-results* of various software with a *considerable*

amount of salt!

c. Which also applies to their *investigative* in-depth test reports

related to any software applications.

d. Investigate claims made by software manufacturer *prior* downloading

their software; Subscribing to noncommercial-type publications,

specialized newsgroups and/or fora (to some extend) are a great way to

find out the 'nitty-gritties' and to consider various options.

Irrelevant. That's an anti-virus program, and you are asking about

Defender, which is an anti-spyware program. They do different things.

I would. There's little downside to running multiple anti-spyware

programs, and since no two of them catch the same set of threats,

having two or three provides added protection.

No.

No. If you want to upgrade the XP Home computer to XP Professional,

you need to buy a second copy of XP Professional (the Upgrade version

will do) and install it as an upgrade.

 

Are you sure you want to do this? XP Professional and XP Home are

exactly the same in all respects, except that Professional has a few

features (mostly related to networking and security) missing from

Home. For most (but not all) home users, even those with a home

network, these features aren't needed, would never be used, and buying

Professional instead of Home is a waste of money. In general, unless

you need to join a domain, you probably don't need Professional.

 

For details go to

http://www.winsupersite.com/showcase/windowsxp_home_pro.asp

 

http://www.microsoft.com/windowsxp/whichxp.asp

 

http://www.microsoft.com/windowsxp/home/howtobuy/choosing2.asp

 

Also note one other point not mentioned on any of those sites:

Professional allows ten concurrent network connections, and Home only

five.

In addition to the other advice previously given, MBAM (malware bytes

anti-malware) is continually being updated. Suggest *never* using an

older version of it as it may not be capable of dealing with newer malwares.

*Always* download the most recent version IF and WHEN a system becomes

infected.

Re: security

 

Thank you kayman for your excellent support/advice. Just to clarify some of

the points you mentioned : both ad and mal are on demand but avg has a

realtime spyware scanner, not sure what you mean by (harden) secure o/s and

i.e. I have sp3 installed and use windows firewall in the system, i have

cable broadband with ethernet modem with Lan settings that are always on

(auto detect no proxy) and if i format the home edition disc will the pro

edition be installed using files and settings transfer wizard using a usb

mass storage flash drive? the later is not important as i can buy a disc for

set up mate. Thank you once again,

Good. The only reasonable way to deal with malware is to prevent it from

being run in the first place. That's what AV software or Windows' System

Restriction Policies are doing; And what 3rd party Personal Firewalls fail

to do.

If on high-speed Internet connection use a router as well.

For the average homeuser it is suggested blocking both TCP and UDP ports

135 ~ 139 and 445 on the router and implement countermeasures against

DNSChanger.

Also: Is the Firmware of your router up-to-date?.

 

For your consideration:

Do not work as Administrator; For day-to-day work routinely use a Limited

User Account (LUA).

Least privilege

http://www.securityfocus.com/infocus/1848

It is important that administrators follow the rule of least privilege.

This means that users should operate their computer with only the minimum

set of privileges that they need to do their job. Typically this means

operating as a normal user,and only when absolutely necessary use the Run

As or MakeMeAdmin commands to elevate privileges.
