Updated 2:45 p.m. PDT with Barracuda Networks warning of Web site promoting rogue program using the Barracuda brand.

Microsoft's Malicious Software Removal Tool was updated this week to detect a generic type of fake antivirus program known as "Win32/InternetAntivirus."

The Microsoft Malware Protection Center gives Win32/InternetAntivirus an alert level of "severe." The software is "a rogue program that displays false and misleading alerts regarding malware, in order to convince users to purchase rogue security software," according to a Microsoft Malware Protection Center blog post. The program also displays a … Read more

Updated June 5 10:50 a.m. PST to clarify that scammers were blending their tweets in with legitimate tweets on an already popular PhishTube topic.

Online scammers are targeting people looking for popular topics on Twitter and Google to lure them to Web sites that display fake security warnings and try to sell them antivirus products, PandaLabs said on Wednesday.

This technique isn't new, but seems to be widening on Google and is particularly successful on Twitter where links are spread fast and furiously and people often don't think before they click.

In the Twitter scam, hundreds … Read more

Twitter users were hit with another attack over the weekend featuring tweets reading "Best Video" and a link to a Web site that downloads malware, a security firm said on Monday.

The Web site, with a .ru (Russia) domain, purports to show an embedded YouTube video. Instead, the page downloads a malicious PDF that contains a "flurry of exploits" and if successful downloads fraudware that displays a fake security warning to try to get people to pay money, according to Kaspersky's Viruslist.com blog.

Contrary to earlier reports that the attack was a worm, the … Read more

By pushing as much resource usage as possible into the clouds, Panda Security's new Cloud Antivirus aims to free up the RAM hogging that plagues many security programs. However, testing the new beta revealed slower-than-anticipated scan speeds when doing an on-demand full hard drive scan. Panda's got a solution that might help some users: turn off logging while running the scan.

Cloud Antivirus splits the usual scanning process into three separate processes. The OnAccess Scan detects executing threats, the OnPrefetch Scan detects non-executing threats that are likely to run in the future, and the OnBackground Scan checks all … Read more

Earlier Wednesday, Panda Security introduced Cloud Antivirus beta, the first full-featured cloud-based antivirus program. It does two things that make it competitive and unique compared with its competitors that are tied to your desktop: it prioritizes threats based on type, and it attempts to lighten the load that security programs place on your system resources by moving definition files to a community-based cloud.

The big concern about a cloud-based antivirus is performance, and Cloud Antivirus handled itself decently enough--although it's not a record-setter. On a ThinkPad T42 with a 1.7 GHz Pentium M chip, 1.5 GB RAM, … Read more

With threats like Conficker fresh in the public's mind, security remains a top concern for Windows users. Panda Security, publishers of Panda Internet Security and Panda Antivirus, is set to take antivirus where it hasn't been yet: into the clouds. Panda Cloud Antivirus beta bets that nearly three years of development can pay off into a better protection system for users. To that end, Panda's willing to make the client free for personal use--even after it leaves beta testing.

You can also download the program from CNET Download.com.

The program uses Panda's proprietary cloud computing … Read more

PCs do the darnedest things. When a program crashes, your system slows down, or a file or program refuses to open, it's probably due to a problem with an application or device. But not always. Computer viruses and worms will cause your PC to exhibit many of the same symptoms as a failed or failing component or program.

Here are some of the primary indicators that your system is infected:

• Your system slows to a crawl for no apparent reason. • The machine crashes, with or without an automatic restart. • Error messages pop up repeatedly. • Programs or files open slowly … Read more

Researchers have discovered another feature of the Conficker worm that provides an additional clue about the intent of the creators--the worm installs malware that masquerades as antivirus software, Trend Micro said on Friday.

The worm, which has infected millions of Windows-based computers on the Internet, is downloading a program called Spyware Protect 2009 and displaying warning messages saying that the computer is infected and offering to clean it up for $49.95, according to the Trend Micro blog.

The infection alerts repeatedly appear and experts are worried that people may be clicking on them and paying for the software just … Read more
