C.cd-sec.com POP-UP Redirect

What is c.cd-sec.com?

c.cd-sec.com is another rogue site that is very similar to other sites of this type. Some examples are onclickbright.com, pttsite.com, and obeyer.com Once visited, it redirects to other untrustworthy or even potentially malicious websites.

In most cases, users visit c.cd-sec.com inadvertently - they are redirected by intrusive advertisements on other rogue sites or by potentially unwanted programs (PUPs). Typically, these programs infiltrate systems without permission, cause redirects, collect information, and provide intrusive ads.

Installed potentially unwanted programs (PUPs) usually open new browser windows and tabs, and redirect to c.cd-sec.com When visiting this site, users are redirected to other dubious (usually 2-3) websites. It is very likely that one of these sites will contain malicious content. Furthermore, redirects caused by c.cd-sec.com can lead to system infections.

Intrusive ads tend to do the same - once clicked, they redirect to various untrustworthy/unwanted websites that might contain malicious content or even execute scripts that stealthily download/install malware. One way or another, clicking intrusive ads can lead to high-risk computer infections (and so do potentially unwanted programs).

Furthermore, intrusive ads are delivered using tools that enable placement of third party graphical content on any visited website.

Therefore, they often conceal underlying content, significantly diminishing the browsing experience. Information tracking is also an important issue - most potentially unwanted programs collect data that typically includes IP addresses, website URLs visited, pages viewed, search queries, etc.

The information is shared with third parties (potentially cyber criminals) who misuse it to generate revenue. These actions pose a direct threat to your privacy and personal identity. Therefore, we recommend that you remove any potentially unwanted programs from your computer immediately.

The list of potentially unwanted programs is long, and most programs of this type are very similar. All offer dubious tools/features and claim to be legitimate, however, they do not deliver any real value for regular users and are designed only to generate revenue for the developers.

Rather than providing the functionality promised, they cause unwanted redirects, gather sensitive information, and provide intrusive ads.

How did adware install on my computer?

Potentially unwanted programs can be downloaded from official websites, however, due to the lack of knowledge and careless behaviour of many users, most infiltrate systems without users' consent. PUPs are often installed by clicking intrusive ads or via the "bundling" method (essentially, stealth installation of third party programs with regular software/apps).

These programs are usually hidden in "Custom/Advanced" settings (or other sections). Furthermore, developers do not disclose "bundled" PUP installations properly, so skipping installation steps or clicking ads can lead to installation of potentially unwanted programs, resulting in a direct threat to your privacy and Internet browsing safety.

How to avoid installation of potentially unwanted applications?

Pay attention when browsing the Internet or installing/downloading software. Bear in mind that developers invest many resources into ad design. Many such ads can seem legitimate, but often redirect to various unwanted/untrustworthy websites.

If you encounter them, immediately check the list of installed applications/browser plug-ins, add-ons, and extensions, and remove any suspicious entries. Do not download software from unofficial websites, avoid using third party software downloaders/installers, and use direct links only.

Check all available "Custom", "Advanced" and other settings/options of the installation processes, and opt-out of unwanted software offered as 'extra features' or 'useful tools'. If your computer is already infected with c.cd-sec.com, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
