JS Downloader in the Virus Chest

On January 11th I got a virus detected notice while on line. I did nothing about it then but on Feb 4th I did a scan and detected JS:Downloader and not knowing what to do I immediately stuck it in the Virus Chest. My computer seems to be working fine but i don’y know what to do with or to the virus. Will you please help? I don’t want to reinfect or delete any necessary files. I’m using Windows XP Home edition version 2002 IE 5, Avast edition 4.8 Home edition Thank you

You did correct. this is probably from an infected website you have been surfing, so i would think this is safe to delete but leave it in the chest for some weeks before you do

Check your computer for Malware with

Have you tried Malwarebytes Antimalware http://filehippo.com/download_malwarebytes_anti_malware/
after install click UPDATE and run cuick scan, click on REMOVE SELECTED to quarantine anything found

SUPERAntiSpyware http://filehippo.com/download_superantispyware/
Are cookies really spyware and are they dangerous?

If anything is found come back and post the scan logs here

If I delete the infected file as you say after several weeks, how can I be sure I’m not getting rid of something critical to my computer? Is there something I can do to clean the infected file in the Virus Chest and revert it back to it’s status before the infection, without unleashing it on my computer? I’m using a dialup connection, so any downloads will be slow, maybe you can direct me to some sites with small downloads for malware cleanup.

That is why you wait several weeks to fiend out before you delete The file is not working now when in chest/quarantine, so if your computer miss it, it will tell you but this was found in Tempfile/IE

Not all files can be cleaned, and this file is not somthing you had in you computer, it is comming from the outside/internett
so your computer want miss it

Clean, Quarantine, or Delete?

Thank you.
Can you recommend any small malware apps that I can check my system with, (I use dialup), or should I just go with the ones you recommend above?
Also, if I’m not experiencing any problems, do you think I need to follow the steps at aumha.net, and report any hijackthis logs there?

Try the ones i recomended, MBAM is the top dog,
you can also try HitmanPro http://www.surfright.nl/en/hitmanpro it is very light but you must be online when scanning, the free version only have 30 days of removal (read all the info on the web site)

If you still have problems or not sure you are clean, then you should follow the guide from essexboy,
post the logs and let him look at it, he is the malware expert

Do you know of any small apps that can clean/check the computer of malware, less than 1 MB of RAM, I use dialup service, thanks

The following was found on scanning with the malwarebyte’s anti-malware app. Please look over and tell me what to do next. Thank you

You should scan again and then click on REMOVE SELECTED to quarantine the infection

Yes I have removed it already to quarantine. But should i then delete it altogether?
What further needs to be done? The Prevx program found no threats at this time. Thank you

@ sweets

Order the Windows XP Service Pack 3 CD to get the system up to SP3 level as Windows XP Service Pack 3 has been available for over a year and a half plus it provides many Critical Updates and performance improvements:
https://om2.one.microsoft.com/opa/Validation.aspx?StoreID=7b7aa929-bd0a-487a-bc7e-df7631fee660&LocaleCode=en-us&JavaScriptOn=yes

IE8 is more secure than IE6 and has a lot better performance:

Go to PROFILE then Modify Profile then Forum Profile Information then Please select your country: then in Signature: put information about your system if you like just like my signature.

In Account Related Settings select Hide email address from public to prevent scammers and spammers harvesing your email address.

Go to Secunia Online Software Inspector then run it to see what other applications are vulnerable:

YoKenny,
Do you think that it is necessary to go to Windows XP SP3 and IE8? Aren’t I just opening up a new can of worms and taking up valuable HDD space? Thanks

You aren’t opening a new can of worms, the can is already open.

Are you saying SP2 & IE6 are now unreliable?
Also I still use a dialup connection. Thanks

Yes we are, not just unreliable but more vulnerable to exploit.

Google and a number of other companies are pushing to block access to their sites and services for users of IE6.

As you are on dial-up get the CD from Microsoft to take the system up to SP3

What country are you in?

I got a friend with broadband to download it for me, save it to CD and that was that. The full SP3 is over 300MB, it is less for an on-line install but still too great for dial-up.

This was the URL I used http://www.microsoft.com/downloads/details.aspx?familyid=5B33B5A8-5E76-401F-BE08-1E1555D4F3D4&displaylang=en, it is still valid.

I’m having someone download and make CD’s for me of Service Pack 3 and Internet Explorer 8. What precautions do I need to take before installing them? Do it offline, shut down Avast, firewall, create a restore point before installing each one, what else ? Thank you
I’m using Windows XP Home Edition version 2002

All I did was to ensure I was off-line, I didn’t shutdown avast, there shouldn’t be a need to do so, but that is a personal choice. I would certainly scan the CD first before using it.

Same thing on the firewall (you didn’t say which you use) as when you install new stuff, it will make note of that so essentially you would need it on, again down to personal choice.

Making a new restore point before each installation is wise, I would also suggest that you do the SP3 one first (don’t believe you can install IE8 before it) and reboot if it doesn’t asks for it (I believe it will) and then install IE8 and reboot.

I’m using Windows firewall, but if I do the install offline does it amke a difference if I turn off the firewall? Any other tips to the install? No need to shut down Avast either? Thanks
