CoolWebSearch – an infamous browser hijacker that bullies web users

CoolWebSearch browser hijacker
CoolWebSearch is a potentially unwanted application which is considered to be one of the most aggressive browser hijackers ever created

CoolWebSearch is a notorious potentially unwanted program that takes place in cybersecurity history as the nastiest browser hijacker[1] ever created. This cyber threat is known to enter Google Chrome or Internet Explorer and modify their settings without warning. Soon after that, the hijacker redirects all searches to Coolwebsearch.com or other questionable sites. The hazardous program comes in a variety of versions (107 to be precise),[2]  all of them using a different code, but behaving very similarly. During its reign in 2005, it infected over 8% of PCs worldwide, which is a massive amount.

Summary
Name CoolWebSearch
Type Browser hijacker
Versions Over 100 created
First appeared in May 2003
Affected browsers Internet Explorer and Google Chrome
Operating system Windows
Distribution Software bundling, fake ads, malicious sites
Symptoms Altered homepage and new tab URL, intrusive adverts and redirects, modifies search results, etc.
Main dangers Malware infection, sensitive data leakage, etc.
Elimination Download and install Reimage; alternatively, you can also try manual removal

Cool Web Search malware is considered to be one of the most aggressive browser hijackers ever made. As soon as it hijacks the browser, it installs multiple dubious bookmarks to porn sites, introduces browser helper objects (BHO) as well as creates shortcuts on the desktop. What is more, it considerably slows down the browser and internet speed. Thus, security experts[3] advise users to remove CoolWebSearch from their machines immediately.

The most annoying feature of this browser hijacker is the advertising content display, as well as its frequency. Users are often bothered by multiple pop-up windows or redirects that occur on a daily basis and conceal the content of legitimate websites. What is more, CoolWebSearch hijack considerably slows down your computer and may even crash your operating system. Additionally, internet speed can be affected too, and getting to even the simplest websites might take a substantial amount of time.

Just like any other browser hijacker, CoolWebSearch can track a variety of non-personally identifiable information, such as:

  • IP address (note: this data may be considered personal, depending on where you live)
  • Internet service provider
  • Technical information
  • Search queries
  • Websites visited
  • Bookmarks added
  • Links clicked, etc.

This data is invaluable for any marketing firm, as it is used as a tool to generate a virtual ID about every user, and display targeted advertisement, making users buy from sponsored retailers. This way, traffic to unknown websites is boosted, and the sponsors manage to sell their products or services much easier. The sad part is, that a lot of these products may be bogus, or end up being a complete scam.

Developers of CoolWebSearch acted like malware authors – they engaged in DDoS attacks

Adding to all this, there is a much darker side to this browser hijacker. When the unwanted program first appeared on the web, it was challenging to eliminate. Since it modified registry entries, it managed to stay on the PC as long as possible, and users failed to remove Cool Web Search spyware, no matter what they did. In some cases, only a completed replacement of Windows registry with the previous version helped. What is more, cybercrooks used ByteVerify exploit[4] to inject their malicious software.

Back in 2004, a Dutch student Merjin Bellekom created a CoolWebSearch removal tool called CWShredder. It got rid of the program fast, and developers of the browser hijacker hated it. Therefore, the bad actors used Distributed Denial of Service (DDoS) attacks to target websites hosting this anti-spyware tool. Countless versions of the application came out, just to counter CWS malware updates.

Fortunately, the tools created back then are already outdated, and if you need to deal with CoolWebSearch, you can use Reimage or SpyHunterCombo Cleaner – these anti-malware applications can get rid of the annoying pest in just a few minutes.

CoolWebSearch virus
CoolWebSearch - a malicious program that can change your homepage and continually display ads

Over 100 versions of CoolWebSearch created

 As we already mentioned, there are over a hundred versions of CoolWebSearch, among them being  Websearch.helpmefindyour.info, Websearch.eazytosearch.info,  Websearch.simplespeedy.info, and many others. Although all of them use a different code, the main goal remains – to redirect users to questionable websites and generate revenue. Here are the two most wide-spread versions on the internet:

CoolWebSearch.control

CoolWebSearch.control is one of the first versions of Cool Web Search, and it aims to infiltrate as many machines as possible using software bundling technique. Additionally, users can obtain it while browsing unsafe websites, such as file-sharing or torrent sites. Just as its original version, it injects several registry entries and avoid removal and proceeds wit hits malicious activities. 

As soon as the hijacker modifies Chrome's or Internet Explorer's settings, the homepage is set to Websearch.coolwebsearch.info. Sadly users are unable to revert these changes until a full CoolWebSearch.control removal is performed. What is more, users have to suffer from continual ads and are as well being spied on by this suspicious software developers. 

Websearch.coolwebsearch.info

Websearch.coolwebsearch.info is a browser hijacker and as well a homepage which is used by many Web Cool Search virus variants. It usually injects users' machines as a drive-by installation, which means that users are unaware that the unwanted app was installed on their PC. The browser hijacker does now label its affiliates ads, as well as does not provide an EULA or privacy policy, which is a deplorable behavior what pretends to be a legitimate company.

This variant of the virus can bring users to dangerous websites, including those which can use JavaScript to inject malware into users machines. All they need to do is merely get redirected to a malicious site, and the consequences could be disastrous. Victims can get infected with spyware, trojan horse or even ransomware. The latter one can lock up (potentially permanently) files and demand ransom for its release.

Therefore, we advise users to immediately take action if any traces of this dangerous application are noticed on the machine.

Users can inject even the most dangerous browser hijackers without noticing

Typically, potentially unwanted applications spread bundled as an attachment of freeware and shareware.  It means that the only way for it to enter the PC is to get user's permission, but since components that spread along with freeware are seldom disclosed explicitly, people who are not keen on checking Advanced/Custom settings can easily end up with various unwanted add-ons, plug-ins, toolbars, and extensions.

CoolWebSearch PUP
The potentially unwanted program injects ads directly into browsers

Thus, if you want to prevent that, you have to check expanded settings carefully and deselect all 'optional downloads' without delay. Note that attachments are set by default, so you will have to untick them before clicking the 'Next' button.

Security researchers noted that suspicious programs could also be obtained on the dubious websites. Therefore, you should avoid file-sharing, torrent, porn, gambling, free online gaming and similar sites. Finally, you should never forget to employ security software with real-time protection feature to be safe.

CoolWebSearch virus removal steps

CoolWebSearch removal used to be extremely complicated when it came out back in the early 2000s. Nevertheless, the security technologies improved over the years and browser hijacker elimination became a relatively easy task. So, you can get rid of CoolWebSearch virus either manually or automatically.

Normally, we would assure that both methods are equally effective, as you can remove Cool Web Search via the control panel and then reset each of the installed browsers (instructions are presented below). However, because this browser hijacker modifies registry entries, and it can intentionally install additional components without your knowledge, we highly advise using anti-malware software. This way, you can be sure that all traces of the dubious app are eliminated.

You can remove virus damage automatically with a help of one of these programs: Reimage, SpyHunterCombo Cleaner, Malwarebytes Malwarebytes. We recommend these applications because they detect potentially unwanted programs and viruses with all their files and registry entries that are related to them.

    Well from the sources of Merij.org (http://www.spywareinfo.com/~merijn/faq.html) they have information about CoolWebSearch. Giving that their text is small by default I'll post what they have about it:

    Coolwebsearch is a company located in Russia. From their site [being Coolwebsearch]:
    Cool Web Search is a Pay-Per-Click search engine. [..] If you get a lot of visitors on your website, we will pay you 50% for each search, that your visitors make on our search engine. We also will pay you 5% of the revenues earned by every webmaster you referred to us.
    Since their emergence last year they have accumulated over 1000 affiliates, all with their own site.
    We know the following people are running/working for CoolWebSearch:
    Louise Vitte (founder)
    Alex S. Hatkinson (programming)
    Serge Stepantsov (programming)
    Victor (site admin)

    CoolWebSearch hires webmasters to promote their website. Those are the bastards that are hijacking browsers.

    Then again, I hate CoolWebSearch. If they were a little more careful with their selection process, we wouldn't have these damn hijackings.

    had the shit a while back , hijacked me to some crap site [cant remember name]. use "startuplist" to see which programs are opening when you boot . good chance you'll find the offender there. it may look like a valid program, bring up the program in the find file area,but, be careful when deleting the bastards, dont take out something vital !!!! also MAKE SURE you delete temporary internet & temp files before you do this , or lo & behold it'll be back. lastly go into your registry [ if you know your way around – it's a dangerous place to play otherwise] & reset your internet settings.

    Had this awful variant on my machine for couple of days. Ran cwshredder….which detected CWS and supposedly cleaned it the first time it ran…but the browser kept getting hijacked. Ran Xoftspy v3.45…in safe mode too..which detected CWS….but again the damned thing kept returning. Subsequent runs of Xoft failed to detect CWS…..but it was there. Also cleaned up the temp internet directory, deleted new installations by the CWS program from "Program Files" and ran ADD REMOVE programs to uninstal any programs installed by CWS…..no success. Finally ran Lavasoft Ad-Aware v 6.0 which detected 57 traces of the bastard program in the registery. Since then the browser homepage has been restored.. Oh yes, don't forget to remove references to CWS parasite programs from the startup control panel…..WildCat
