Maximum protection of your pc

[mehdisami]

Hi,
there is viruses that no anti-virus can find it, because it is Encrypted , the best way to protect your machine is to:
1) setup an anti-virus . eg: (Kaspersky)
2) setup a firewall . eg: (ZoneAlarm)
------------->3) setup a DeepFreeze <----------------------
--> if your windows is in drive C use DeepFreez for only this drive (to protect the system)

4) every week or 3 days ,setup updates for anti-virus and firewall
by holding Ctrl+Shift+Alt -->F6 --> your password --> Ok --> boot thawed --> Ok --> restart your machine --> setup updates -->Hold Ctrl+Shift+Alt --> F6 --> your password --> Ok -->boot Frozen --> Ok --> restart your machine --> work normaly...

that's all about best security config.

Hey thanks for the valuable information and steps. I can definitely protect my system from those viruses.

Thanks again

DeepFreez restores your pc to an image so any changes you have legitimately made would be lost as well, you may as well reinstall your operating system every week. And I'm not convinced there are viruses that absolutely nobody can find - if they are there what are they doing? It can't be much otherwise you would notice the effects even if you didn't know why. And encryption wouldn't stop an anti-virus program finding a virus anyway - they just don't work like that.

Have a firewall installed, keep your A-V program up todate and be sensible about what you download/open. Anything more than that is completely over the top.

"DeepFreez restores your pc to an image so any changes you have legitimately made would be lost" -->you can setup the DeepFreeze where you have your operating system ,EG: if
* you have drive C,D,F
* operating system in C
--> you will setup Deepfreez on the C.
--> when you want to make a serious changes (like a setup of new programs)you will boot thawed DeepFreeze and make your changes ..

"you may as well reinstall your operating system every week" -->
Why reinstall operating system?
you will never need to reinstall operating system !

"And I'm not convinced there are viruses that absolutely nobody can find - if they are there what are they doing"-->

viruses are programs ,and the programs can be Encrypted.


"And encryption wouldn't stop an anti-virus program finding a virus"-->

anti-virus will guess that virus is a file system (like explorer.exe for example)
or any other normal file .
and you can not say that the updates contain all types and names of viruses ,as there is an update there is a new viruses .
for example Kaspersky can find virus that norton a-v never can find !

"Have a firewall installed, keep your A-V program up todate and be sensible about what you download/open. Anything more than that is completely over the top" -->

there is some websites put in your pc a programs (viruses ,trojans..); without downloading any thing, just when you open the website !!
EG: open that website and your computer will be the house of viruses (Realy): ****www.gookle.com**** OR
****www.googkle.com****

+++
when your A-V can't find virus try to do this :
go to Start->Run->regedit-> select : HKEY_LOCAL_MACHINE ->SOFTWARE->MICROSOFT->WINDOWS->CURRENT VERSION . and look in
"Run" and "RUN ONCE" and "RUN SERVICE" .then search for suspicious files like:
PATCH.EXE or EXPLO32 or server.exec or :\windows\Expl32.exe or Explorer32

+++
and be careful about the free versions of Linux , any programmer can modify or remove the security system.

Firstly I personally think that ghosting an image of your operating system every time you make a change to it and then reinstalling from that ghost image every week is massive overkill for anyone who isn't a systems admin for a set of public machines.

Secondly modern AV programs don't need to have a virus definition to detect a virus - they use heuristic detection methods as well. Encrypting a virus is a really crude way of hiding it because it will still require decrypting to run. AV programs just search for the decrypter rather than the actual virus. In addition it can still be found heuristically because once decrypted it will actually have to do something and it is this behaviour e.g. modifying system files that the AV software will look for.

Thirdly Websites can only install software outside of the browser sandbox with your permission. Admittedly IE6 used to have so many holes you could pretty much give someone permission to do anything without realising it but FF, IE7 etc are much more paranoid. Oh and I went to both of those sites and survived to tell the tale.

Fourthly - it was a joke about Linux yeah? All versions of Linux are 'free' and to suggest that most open source programmers would deliberately open an OS up to viruses or other malware is paranoid beyond belief.

And finally...I spend most of my working day and a fair amount of my leisure time online and in the 9+ years I've been doing that I can count the number of virus infections I've had on one hand and when I have been infected in all but one case (I picked up the Sasser worm quite early on) my AV identified and quarantined the problem.

Like any other activity spending time online has risks which you should act on to minimise but going over the top and being paranoid just stops you having fun.

I agree with Kev, I've been active online for a long time and I have never had an infection that disrupted my computer. So long as you use common sense, have a virus checker, firewall and keep your software up to date you are pretty much safe.
