Offline disinfection

[iSyntax]

Good day co-Techs.

Im a newbie technician and currently undergoing computer maintenance training by myself.

I have a little problem.

I wonder if it is possible to disinfect/clean a computer which is not connected to the internet? (if there's no way to update anti-virus' virus database)..

I also heard about bootable antivirus and portable anti-virus, can i ask for some guide about this thing?

Sorry for very much questions.

I verily appreciate your replies..

Regards
~Syn

Uhm, can i use these things even if i am in offline mode?

~Thanks!

 

[kimsland]

Yes, that's the point

You download them first (on an online computer)
Then save them to CD or USB Flash drive or something
Then use them on the online computer

Oh, I forgot CCleaner

Is there any way to bring them updated to the infected computer?

Can i save the updated virus database to CD? Most of the anti-virus in the web isnt updated.

Btw, thanks sir Kim.

The above tools downloaded will be current as of the date of downloading
In other words nothing to update

But I agree the only time an Antivirus program has the included updated definitions is when they release a whole new version. But it's only current for a day or two anyway

Really these days you need online ability to service computers. Gone are the days where technicians carried a briefcase of CDs and manuals. Now it's one USB drive and the Internet

I guess i lost in the past techie life, i really need new techniques.

I cant even make a full protection in my own pc.. i heard that most of the viruses came from p2p.. and porn, but ofcourse i dont watch porn.

Can i have some security tips?

Thanks sir kim.

Well obviously this is step 1 (well 8) : Have a look at:

UPDATED 8-step Viruses/Spyware/Malware Preliminary Removal Instructions

But I'd also recommend a good Hosts file

You may want to update to a more secure Hosts file
There's lots of important info on that here: http://www.mvps.org/winhelp2002/hosts.htm
As it's difficult to see the actual download, here it is: http://www.mvps.org/winhelp2002/hosts.zip
Important! Windows Vista requires special instructions: http://www.mvps.org/winhelp2002/hostsvista.htm

Simply download the hosts.zip file, extract, then run mvps.bat, then restart

[Important Notice - 2K/XP/Vista Users]
In most cases a large HOSTS file (over 135 kb) tends to slow down the machine. This only occurs
in W2000 and XP. Windows 98 and Windows ME are not affected.

To resolve this issue (manually) open the "Services Editor"

Start | Run (type) "services.msc" (no quotes)
Scroll down to "DNS Client", Right-click and select: Properties
Click the drop-down arrow for "Startup type"
Select: Manual, click Apply/Ok and restart.

Then restart, and test browsing the Internet again

Thank you so much sir Kim.

It will help my study. I really like this site, im learning a lot of things

 

[kimsland]

Good point read other threads and learn
There is consistently some malware thread going on
Some are really quick, some take a long time
There's no set way of handling every single infection out there with one set procedure

 

[iSyntax]

Yes. Thank you sir.

And oh, the guide section is really good, nice software and utilities download.
Thnx sir, u can leave me now

Cia around.

 

[kimsland]

Yes seeyu around

Thanks for the update :grinthumb
