An old nuisance, Backdoor_Win32/Gaertob.A, has returned, and is leaving PC users shaking their heads and tightening their Internet security defenses.
Backdoor_Win32/Gaertob.A is a nasty, deceitful Trojan first detected in January, 2009, and goes by the aliases Trojan.Win32.Buzus.ctwu, W32/Obfuscated.A!genr, and Win32/Buzus.CTTV. Infamous for exploiting vulnerabilities of IE and other software, Backdoor_Win32/Gaertob.A may have been cloaked inside an infectious download of freeware, shareware, or a codec.
Once inside your PC, Backdoor_Win32/Gaertob.A will waste no time and will modify security settings to disarm your anti-malware, and add itself to your Windows firewall applications to avoid detection and removal.
Do not be surprised if you are forcibly and repeatedly routed to a malicious or undesired website. Backdoor_Win32/Gaertob.A has intelligently modified your hosts files, and may also block you from downloading helpful programs such as a legitimate anti-malware tool to remove it.
Another dirty trick used by Backdoor_Win32/Gaertob.A is to modify your browser settings and change your home page settings to gllod.com, an accomplice in Backdoor_Win32/Gaertob.A dirty scheme and malicious attack. Therefore, do not trust or believe gllod.com's attempt to look like a legitimate Google search page, it is fake! Gllod.com and its infectious gllod.exe file are part of the scam of Backdoor_Win32/Gaertob.A, and you should have both removed immediately. Be certain to keep an up-to-date anti-malware loaded on your system in case you trip over a dubious link or unintentionally land on a malicious website like gllod.com.
Two Additional and Important Tips:
- Once backdoor_Win32/Gaertob.A is on your machine, a remote attacker can order a check of P2P folders under the program files directory and can drop copies of backdoor_Win32/Gaertob.A into each. You need to know that you may become the 'spreader' of this nasty disease to your friends and family.
- To ensure you do not 'trip' or mistakenly visit gllod.com, you may want to block it from your browser by doing the following:
- Go to the start menu and open your host file
- To bypass the restriction, right click on the 'notepad' application and opt to 'run as administrator'.
- Open your host file (it is usually found here: C:\windows\system32\drivers\etc)
- List the sites you want blocked underneath the line that identifies your local host (example below)
#127.0.0.1 localhost
#127.0.0.1 *xyz.com (substitute 'xyz' for the name of actual site to be blocked)
Note: The asterisk should block all variations, i.e. www.xyz.com, xyz.com, http:www.xyz.com). If it doesn't, list them individually.
