How to protect our company with anti-virus protection for Asian viruses?

Question

Our company recently had someone from overseas China connect their laptop to our network system. Ever since then, our internet has been running really slow, one of our database servers completely crashed, and a lot of other misc. computer problems. We have deduced that the China laptop may have infected our network system with some kind of chinese virus which cannot be scanned or fixed by the american anti-virus protection we currently run.
Is there some kind of chinese antivirus protection software that I can obtain to run on our network system to try and scan for the infection?
Or does anyone have any ideas on how to rectify the situation....other than reformatting all our computers in our company>
Thanks!

Answer 1

Use Linux as OS in your servers.

Try a online antivirus scanner and a online anti-adware/malware/spyware scanner in safe mode with network to clean up your computer BEFORE you download anything.

Turn off system restore before you boot up in safe mode with network to clear your system restore points for viruses, spyware, adware etc.

To get in safe mode tap F8 when booting you computer.
Choose "Safe mode with network".
Go to Start – Run - type iexplore http://www.bitdefender.com/scan8/ie.html Enter(ok).
Do a full system scan. If something is found, delete it, reboot and do the same again in safe mode with network.
When that scan does not find anything you reboot again in safe mode with network.
Go to Start – Run – type iexplore http://www.ewido.net/en/ Enter(ok).
Do a full scan. If you find something, delete it, reboot and do the same again in safe mode with network.

**NOTE: Do NOT do anything else with your computer when scanning. This because you can start virus/adware/spyware/malware manually.

When no one of these scanners are showing anything you can reboot back to normal mode.
Turn on system restore.
------------------
You need to get one antivirus program, one firewall and some spyware/adware/malware removers if you don't have it.
I use Norton Internet Security on my desktop running XP Home SP2 with Firefox.
On my laptop i have Ubuntu 7.04. No security needed in Linux, but i have antivirus and firewall.

Spybot-S&D Free.
http://www.safer-networking.org/en/mirrors/index.html
Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there's no harm giving it a try to see if something has invaded your computer.

AVG Anti-Rootkit Free.

If a threat uses rootkit technology to hide itself it is very hard to find the malware on your PC. AVG Anti-Rootkit gives you the power to find and delete the rootkit and to uncover the threat the rootkit is hiding.

CCleaner free.
CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it's fast and contains NO spyware or adware.

Also scan with online scanners sometimes.

Answer 3

I am a board certifed clinical psychiatrist and have a moral and legal obligation to keep my pc 100% clean.

Here are program I use that will give you 100% protection. Ofcourse you must also have all your critical updates installed from Microsoft.


Antivirus program I use. You only pay a one time fee of $29.99. and you get all updates and all new versions for life.

Read the webpage and if you like what you read this is the antivirus of choce I have used for over ten years and never one virus.

By culture the Chinese are very secret just about everything and that includes their software.

This antivirus program out of Beijing, China that is also used by the Government of China.

This antivirus program does not have the Govt. permission to be rated with all other known antivirus programs.

What I can assure you is that you pay only a one time fee for life that will include all auto updates, and all new versions for life. The Chinese don't believe in having to pay an annual fee for updates or new versions.

I can tell you their technology is light years ahead of any other known antivirus software out there.

If you open a webpage and there is a hidden virus it will clean in realtime. Anything that you download and has even a trace code, it will kill the download and ask you to upload the trace code for investigation. In real time the upload will tell you if it is clean or not.

Will not allow you download, Real Player, because there is a hidden file that is a trojan keylogger. The file was uploaded and traced back to the United States Army, Intelligence Services out of London, England. (Removal of the file Real Player will reject the installation).

Read for yourself at their webpage. I have never had one virus in ten plus years. Plus it will catch any progam with it's dynamic defense system, for software that you download and it does not have a publisher or lic., included.

Twister Trojan Antivirus V7

Very low on resources with scanner running in background.

http://www.filseclab.com

These new viruses from China, are being used alot now, because they are unknown to American antivirus/antispyware software and they are missed when you scan your system..
