Ad-Aware Web Companion - Cloud System for Malware Filtering

Not open for further replies.

Ray Redbad

The long-established Lavasoft Ad-Aware Security Toolbar, a stand-alone solution as well as an opt-in bundled with all Ad-Aware AV product installers (and "necessary" only in Free AV+), is being replaced with Web Companion.

Yes, it's FREE!!

While the Toolbar is, well, a browser toolbar, Companion is an in-line process. Branded as Lavasoft MUB is the real-time "URL Lookup Cloud System for Malware Filtering." One might conclude some benefit from their partnership with Bitdefender: "...intelligence shared with industry security partners."

One partner is surely Malware Domains. There are three constantly updated local files, and a Malware Domains txt file and two password protected zip files named hourly and weekly from Malware Domains' URL Labs. Generally this strategy is employed to reduce load on the cloud services. And a first-tier filter, no doubt.

Mentioned is Lavasoft CMP with no mention what CMP means. (I'll try and find out.) EDIT: Content Malware Protection.

I ran the Beta and found it installs a TCP Service and a Search Protection Service which filters via the local proxy (aka, aka loopback). Theoretically, that should offer protection across all Web enabled applications, not just the browser, but they don't make that claim - rather "advanced web protection." Read into that what you want.

I did not find any Bitdefender libraries or drives associated with the Companion run time or services.

The settings UI access is by a tray icon.

When installed with an Ad-Aware AV, my thinking is that it will add a long-absent cloud component to their product offerings. It should greatly enhance Free AV+ which begs for a better zero-day protection level. For the paid versions, I hope Lavasoft can manage to integrate the cloud as an application core as I am not particularly fond of processes (other than system) using the local proxy.

Currently in Beta, the production release is scheduled sometime in September which is almost now.

Wait and see... Cheers.

AVIRA PRESS RELEASE - Lavasoft Enters Multi-Year Agreement with Avira Antivirus to Further Enhance the Capabilities of Ad-Aware Web Companion

"Lavasoft, makers of award-winning free antivirus and antispyware Ad-Aware, has entered into a multi-year agreement with Avira to license its new cloud-based malicious URL (MURL) and program classification service (AUC). Compatible with a user’s existing antivirus program, Ad-Aware Web Companion works with the top browsers on the market to provide complete protection against malicious web content and dangerous phishing scams.

“When the Avira URL Cloud meets Lavasoft’s Ad-Aware, it’s win-win situation,” said Travis Witteveen, CEO of Avira. “In addition to enhancing Lavasoft’s ability to protect users from malicious websites, this deal shows the value from integrating Avira’s technological expertise into products from other leaders in the security space.”

Avira builds its own MURL lists by analyzing samples collected through automated sandboxes and the malicious sites encountered by the 100-million-users of Avira Antivirus. Avira further applies a battery of advanced heuristics in real time to assess new threats submitted to the Avira cloud.

To increase the Web protection capabilities in its Ad-Aware Web Companion, Lavasoft has an upcoming beta release, which will be followed by a public launch. In addition to its agreement with Avira, Lavasoft will continue to add third-party antivirus services to ensure users receive the world’s absolute best web protection."

Looks quite good trying it in a VM now, lags at startup and STILL buggy.
