The worst virus i have ever had

[Lisandro]

I think I am cured finally.

So, now, immunize your system with SpywareBlaster or Windows Advanced Care.

Also, check if you have insecure applications with Secunia Software Inspector.

Oh, don't start/run files that you don't know the origin, surf safely

Thanks you all rock 
Now, a last question. Must I have both a router firewall and a software firewall (since I am using a router) to be safe ?
Right now I am using only my router's firewall.
If yes, can you recommend a good free firewall , except that of Windows (which I think is not the best,but if you tell me it is then ok)

[sanctuary24]

If its for Windows Xp 32 bit I think Comodo Firewall Pro is ok, but you may want to check your system against the specifications on its website

www.comodo.com

its free like you asked

Oh btw what did you mean when u said a firewall of a router is not enough to prevent unauthorized access to my PC? If I had a software firewall and a router firewall then things would be difficult for my web right?

Short answer it provides zero outbound protection.

Any malware that manages to get past your defences will have free reign to connect to the internet to either download more of the same, pass your personal data (sensitive or otherwise, user names, passwords, keylogger retrieved data, etc.) send out spam emails or open a backdoor to your computer, so outbound protection is essential.

The software firewall shouldn't impact your router/firewall.

Check my sig below for links to the browser, real-time anti-spyware & firewall I recommend.

Set scheduled scan in Spyware Terminator to "never", it can be annoying.  I recommend on-demand anti-spyware scans with SuperAntiSpyware.

Opera can help protect your system from malware while surfing the web.

WinPatrol is highly recommended.

All are available for free.

[FreewheelinFrank]

Which online scanner picked up the malware, by the way?

I use Zone Alarm Free on Windows: it's still the easiest to understand of all the firewalls I've tried.

can you recommend a good free firewall

For Windows XP, Comodo for sure.
Despite ZA is a very simple (easy to understand) firewall, I think it has much *issues* and problems. Also that much bells and whistles like a bloatware suite...

I installed comodo and everythings fine

Good. Enjoy. Comodo has a free forum if you need help.
Here there are some users that can help you too.

I think that statement crosses the border into FUD territory.

For many users, ZA has no issues, or problems, is stable and works well, including me at the moment.

I have had issues with ZA in the past, but I have had with Kerio/Sunbelt and Comodo too: no software is perfect.

I honestly don't know what you mean by bells and whistles: ZA Free has no unnecessary features.

Bloatware? ZA free includes the option to install the pay version. There is a very clear option to decline. ZA is a commercial company and they want to sell you one of their products: that's their right.

They also make available a free firewall which has been one of the most respected products in the area for years.

Let's try and give some unbiased advice to people rather than the latest fashion, please.

Not FUD. Bad personal experience, just this.

For many users, ZA has no issues, or problems, is stable and works well, including me at the moment.

I do not doubt about this. Just for me, it is not good: bloatware (antivirus, etc.), no network configuration available (ports & applications), no parental application control.

I honestly don't know what you mean by bells and whistles: ZA Free has no unnecessary features.

They 'ask' for the paid version, i.e., a lot of disable features announced in the free interface.

They also make available a free firewall which has been one of the most respected products in the area for years.

Ok. I think they've lost this 'good press' lately.

Let's try and give some unbiased advice to people rather than the latest fashion, please.

I try. It's my bad personal experience.
Besides all of this, Comodo does not work in my Vista and ZA does (with delays, but it works).

[DavidR]

Zone Alarm free for the most part works fine with avast and has a reasonably friendly user interface, however, the free version is also crippled as far as outbound protection goes In the Program Control, configuration area, the slider will only goes as far as Medium protection, if you want more you have to buy the Pro version.

That factor lessens the outbound protection greatly, whilst that limited protection is better than XP's firewall it doesn't match the protection available in other free firewall solutions. You need only take a look at http://www.matousec.com/projects/windows-personal-firewall-analysis/leak-tests-results.php, to see the difference between the free and pro versions of ZA. However, I have no problem with ZA trying to promote the paid for option in this way, the programmers have to eat and ZoneLabs has to survive. But, when you compare the free and even the pro version against a number of other free firewalls you see how much the free version is lacking.

Excellent advice for anyone recommending Comodo!

Excellent advice for anyone recommending Comodo!

Why?

Precisely. The free version of ZA loses when compared to other free firewall, in my opinion.

You should then follow your excellent advice and apply it to any negative comment on another firewall and back-up the comment, which I guess it not for recommending Comodo.

But, when you compare the free and even the pro version against a number of other free firewalls you see how much the free version is lacking.

ZA Pro is also beaten by some of the free firewalls too.
