How S.coldsearch.com Browser Hijacker Works

It uses strategies of infiltrating without you realizing it mean while getting your acceptance for its installation. The product hinges on the everlasting techniques of Spamming, Spoofing, or installing Spyware to enter your system. The virus crawls in by camouflaging behind unsolicited e-mail add-ons, links, or websites. The malware can also appear as a duplicate system or application update, like Java or Flash. That’s mainly because consumers dash through its installment and don’t even make an effort to go through the terms and conditions. Instead, they make the conscious choice to agree with pretty much everything. Well, that’s a horrible decision with awful repercussions.

Disabling ActiveX

Table I shows some settings that involve ActiveX in the Internet security zone for IE 7. Changing this small group of settings will still protect against many common security problems but is less of an obstacle for the average home PC user. Some ActiveX settings are already disabled by default in the Internet zone and those listed are additional settings that should also be disabled. The settings can be changed manually by going to the Internet Explorer menu Tools-Internet Options-Security-Internet-Custom level (Figure 1). Note that some Web sites use ActiveX and there may be loss of functionality. In particular Microsoft sites such as Windows Update will no longer work. To retain ActiveX capability, commonly visited sites that are secure can be placed in the Trusted Zone. Or, if desired, settings can be returned to their default values by clicking the Reset button shown in Figure 1 or by using the Default Level button.

Table I. Settings for Disabling ActiveX in IE 7
Category Setting Default Recommended
ActiveX controls and plug-ins Binary and script behaviors Enable Disable
Download signed ActiveX controls Prompt Disable
Run ActiveX controls and plug-ins Enable Disable
Script ActiveX controls marked safe for scripting Enable Disable
Figure 1. Dialog box for settings in Internet Security Zone

Quick way to change IE security zone settings.

Rather than changing the settings manually, an INF file that makes the changes in the Registry can be used. (Using INF files to make Registry changes is discussed on this page.) This has the advantage of providing a simpler method that is not subject to possible errors in entering setting changes by hand. The INF file that carries out the changes shown in Table I can be seen here. The text file shown can be copied and changed to an INF file by editing the extension. To make things even easier, I have also wrapped the INF file in an EXE package that can be downloaded here. To use it, simply left-click in the usual manner. If you do not like the results, the changes can be undone with another executable file that can be downloaded here. Note that any additional setting changes that you might have made will not restored by this file. As is true for any executable file, your security settings may give the standard warning.

Because of our litigious society, I must make the disclaimer that all files are provided as is, without guarantees, and that the user assumes all responsibility.

Responding to zero-day exploits

Many so-called zero-day exploits have been making use of ActiveX. In these cases,Microsoft often advises the work-around of disabling Activex until it issues a patch. The downloads provided above provide an easy way for PC users to apply the temporary defense.

Description of the “My Computer” or local Internet security zone

The “My Computer” zone is the local computer zone, which governs the security settings for opening HTML pages stored on your own system. These locally stored pages are deemed to be safe, which is normally a reasonable assumption. Also local pages may need access to the resources such as files that are located on your system and are therefore given a high degree of trust.

Unfortunately, there are a large number of cross-zone vulnerabilities, which writers of malware such as viruses, worms, etc. may use to their advantage. To help plug these security holes, one of the security changes made in the Windows XP Service Pack 2 update locks down the  “My Computer” zone to control the running of scripts and ActiveX components. This increased security comes at a cost, however, since certain applications are thereby broken.

Configuring the “My Computer” Internet security zone

Users of older Windows operating systems will not receive the security updates for Internet Explorer that the Windows XP SP2 contains. In these cases it may be desirable to be able to configure the settings for the “My Computer” zone. (The following procedures do not apply to IE 6 in Windows XP SP2 or to IE 7.)

Configuring Internet Explorer zones is done through the “Tools- Internet Options ” menu. (A tutorial is available on another page.) The zone for “My Computer” is normally hidden but it can be made visible by editing the Registry so that this zone appears on the Security tab in the Internet Options dialog box, as shown below.


The Registry settings that have to be changed to make this zone visible are given in an article in the Microsoft Knowledge Base . The key that has to be edited for a particular user account is

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0

The key to be edited if all user accounts are to have this zone visible is

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0

Within the key is a DWORD value “Flags”. Setting the data value of the Flags value to 47 (in hexadecimal) causes the “My Computer”security zone to be displayed. Setting the data value of the Flags value to 21 (in hexadecimal) causes the “My Computer” security zone to be hidden.

Editing the Registry can be a parlous project so be sure to back up the Registry first. For those who understand how to use REG files, copy the text below, paste into Notepad, and save as “showmycomputer.reg” or name of your choice. Only those who can return their computer to a previous state should try this.

Makes “My Computer” security zone visible

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0]


To reverse the process and hide the zone “My Computer”, use the following script

Hides “My Computer” security zone

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0]


For details about strengthening the security of the Local Machine or My Computer zone consult this Microsoft article.

Types of cookie

In managing cookies, there are two basic types to consider. “First-party” cookies are those that come from the same domain as the page that you are viewing and are available to be read by the site that you are viewing. This is the type of cookie used for logins, for example. They also may be required by a site before it can be viewed properly. “Third-party” cookies are sent by or can be read by a site different from the one being viewed. These are from sites that provide material to a page that you are viewing, usually advertising. Most people feel that this type of cookie can be safely filtered out. (Marketers may disagree, of course.)

Cookies are also classified according to how long they live. “Persistent” cookies are downloaded to your computer and remain in effect for some period of time called the lifetime (unless they are deleted). Sometimes the lifetime is set for years. “Session” cookies are kept in temporary memory and are alive only during the time that your browser is open.

Cookie management with advanced privacy settings

Cookies are managed in IE6 and IE7 through the menu “Tools-Internet Options”. (Internet Options can also be reached through the Control Panel.) Some details are given in this tutorial. The figure  below shows the dialog box obtained when the “Privacy” tab is selected from “Tools-Internet Options”. To use the advanced settings, click the button “Advanced” outlined in red (not the tab at the upper right.)


The dialog box for “Advanced” settings is shown below. Place a check in the box by “Override automatic cookie handling” and click “OK”.


After checking the box, the dialog box looks like the figure below. Settings for First-party cookies, third-party-cookies, and session cookies are available. The settings shown are probably the optimum for many PC users. Blocking third-party cookies keeps out a lot of advertising related stuff and does not interfere with the functioning of any sites that I am aware of. Put checks by the settings you prefer and click “OK”.


If you do not like the results from using the advanced settings, return to the Internet Explorer menu “Tools-Internet Options-Privacy”. The default configuration can then be restored by clicking the button “Default” as shown in the figure below.


Using an imported privacy file

A lesser known but very useful feature in Internet Explorer allows the management of cookies by importing what is known as a privacy file. The privacy tab dialog box for Internet Options contains a button “Import…”. This is shown in the figure below. Details of how to use this type of file and some examples are given at http://www.vlaurie.com/computers2/Articles/custom_privacy_file.htm. The procedure for constructing a customized privacy import file is dicussed at http://www.vlaurie.com/computers2/Articles/custom_privacy_file2.htm.

The origin of using the name of the Hormel Company canned meat product for junk email is attributed to various sources, including Monty Python. Whatever the origin of the name, spam is a truly major email nuisance. The ease with which large electronic mailing lists can be set up and the essentially cost-free (to the mailer) process of email means that almost anyone can send out huge quantities of advertising or other messages. Around half of all email is estimated to be spam.

How They Find Us

In theory the best defense against spam is stay off the mailing lists. So how do we get there in the first place? Unfortunately, it is almost impossible to keep your email address hidden from determined marketers. Once on a list for any reason, your address may be sold and resold many times until it is on dozens of lists. CDs with millions of email addresses are readily available for a few dollars. Any action that you take that might expose your email address on the Internet can end you up on spammer’s lists. Participation in chat rooms, newsgroup discussions, investment forums are all ways to get on lists. In a practice called “harvesting,” spammers use software called “spiders” to regularly comb the Internet for addresses. Also, many ISPs offer the option of being listed in a directory and these are fair game for advertisers.

Shopping on the Internet, signing up for newsletters, entering contests, registering to download software, or other activity requiring that you provide your email address can also get your name on lists. Although reputable merchants, newsletter writers, shareware sites, etc. will respect your privacy, some sites may feel free to sell your name to others. Always look for a statement of the policy on privacy before signing up for something.

Another method used by spammers is the “dictionary” attack. By combining all common words and names (with variations like joe1, joe2, joe3, etc.) with all the common providers such as AOL, Hotmail, MSN, Earthlink, computer programs can generate millions of possible email addresses. Many of these will be legitimate and the spammer doesn’t care about the ones that bounce. The cost of mailing to a lot of incorrect addresses is too small to be any deterrent. Thus some people advise using uncommon combinations of symbols for your email address.

Everyone should have several disposable junk email address that they use where public exposure is likely. One of the free services like Hotmail or My Yahoo serves admirably for this purpose. If an address starts to attract spam, it can just be discarded.

You can also “munge” your address in places like Newsgroups. To “Munge” is to add easily recognized extra characters to your address along with the accompanying phrase “remove xyz to obtain address”. Thus myname@myISP.com becomes myname@mynospamISP.com. The only trouble is that address harvesting software can be programmed to strip out obvious strings like nospam although many times they don’t bother.

Blocking Spam

One method of dealing with spam is to block or filter mail from known spammers or that contain particular subjects or key words. This can be done either on your email program or with special software. The common email programs like Outlook Express allow for setting up rules that apply to categories like senders, subjects, and textual content. Check your particular email client for the details. For example, in Outlook Express go to the menu under Tools-Message Rules. The problem is that spammers keep changing or faking their ostensible names and addresses as well as using phony subjects. Personally, I have found that rules and filtering within my email program may keep out some spam but that it is only a partial answer to the problem. You can also install some extra software. There are a slew of utilities devoted to stopping spam. The best types of programs use a statistical technique known as Bayesian filtering. These programs set up filtering rules based on actual experience and “learn” how to improve filters from the email that you receive. See the sidebar for references on this technique and on various software programs.

Businesses and those who are big users of email will need some heavy-duty methods of filtering spam but average PC users who receive only a few emails each day can use a program like MailWasher Pro. Also, ISPs are getting better at filtering and may also provide some way for individual users to create filtering rules.

There are also services that will filter your mail. By collecting large databases of known spammers and using their client’s emails to keep up with the latest tricks and twists of the spammers, these services can be better at stopping spam than software located on your own computer. These services naturally slow down the processing of your mail since it has to go through their server. Several are listed in the sidebar.

Note that no matter whether you filter mail with software on your own computer or use an external service, some spam will get through and some legitimate mail will get blocked.

Although there are many ways to try to block spam from arriving in your mailbox by using software or filtering services, my experience is that spam has reached the point where one of the best defenses is to have more than one email address. You can reserve one address for friends and relatives and have a second throwaway address that is changed fairly regularly. This second address would be the one that is used whenever it might be subject to public exposure. Many ISPs allow for an account to have multiple mailboxes and one can be set aside for junk. If the volume builds up, the box can be discarded and replaced by a new one. Another route is to use one of the free Internet email services like Yahoo or Hotmail. Yet another approach is to use one of the services that provide email addresses with a limited lifetime. For example, SpamGourmet will give you addresses good for a certain number of uses only.

The last and perhaps best defense is common sense and the “delete” key. Don’t open obvious spam messages and be very careful about responding to “Remove me from this list” type of addresses. That may very well just get you on more lists. Also note that formatted spam may contain Web Bugs that tell the spammer if you have opened that mail.
