LessTabs

LessTabs Description


Marketing for LessTabs proclaims LessTabs as a utility that enables you to examine various website links without any need to open a new window or tab. However, while LessTabs does seem to provide this function, malware experts also have analyzed several undesirable elements in LessTabs that can make LessTabs classifiable as adware or a Potentially Unwanted Program (PUP). LessTabs alters several browser settings in ways that can reduce your web-browsing security, installs itself to all major browsers by default, and – most visibly – displays advertisements to derive easy revenue from anyone who uses the LessTabs plugin. Adware like LessTabs typically should be deleted on a regular basis, and doing so (hopefully with relevant anti-malware tools) is especially encouraged on account of the security issues raised by LessTabs’s mere presence.

LessTabs for You… Means More Money for LessTabs Than Usual


To LessTabs’s credit, LessTabs does offer some legitimate web-browsing features that you may or may not find convenient. However, SpywareRemove.com malware experts are forced to warn any would-be users of LessTabs that this program’s drawbacks outweigh its advantages by a fairly heavy margin. It also should be emphasized that, since LessTabs’s installs itself to all common brands of browsers by default, these changes are relevant to all of your browsers (unless noted otherwise):
  • LessTabs will insert advertisements into the websites that you browse.

    These advertisements appear to be LessTabs’s main revenue source and can vary in format, including pop-ups, pop-unders, banners and text-based links.
  • LessTabs increases the time threshold of the IE Load Time Alert.
  • LessTabs disables Internet Explorer-based Accelerators.
  • LessTabs will disable the Content Security Policy, which guards against script exploits and data injection attacks (like the adware functions that LessTabs uses to enable its advertisements).

While LessTabs elaborates on all of these ‘features’ freely and claims that they are implemented for the quality of your web-browsing experience, SpywareRemove.com malware researchers can see little justification for them, and particularly consider disabling the CSP to be a dangerous and unwarranted function.

Why Less is More When It Comes to Your Browser


Unnecessary browser add-ons with exceptionally risky side effects, such as LessTabs, always should be removed from your computer regularly, even when their side effects don’t cause any immediate exposure to malicious web content or other PC threats. Since LessTabs makes a range of browser-indiscriminate settings changes that can endanger your computer’s web-browsing safety, SpywareRemove.com malware researchers suggest you use anti-malware tools to clean up LessTabs and the system changes that follow in its wake.

Advertisements associated with LessTabs don’t appear to be screened for your safety, and LessTabs explicitly denies any responsibility related to the content of the advertisements and sites that LessTabs promotes. With this kind of problems on your mind, if you do find your browser being subjected to LessTabs’s advertisements, you should avoid any needless contact with them – no matter how good their offers may seem at a first glance.
