Customers of the antivirus/antimalware company BitDefender ran headfirst into a major problem over the weekend, courtesy of a (very) faulty virus definition update for systems using 64-bit flavors of Windows. After installation, users flooded the company's forums complaining that BD was now identifying every executable on the system as being infected. To its credit, Bit Defender responded quickly to the situation; the update was apparently yanked less than a day after it was made available. The following is an exerpt from BD's official webpage on the topic: "Today BitDefender products running on Windows 64-bit systems experienced problems caused by a faulty update. Multiple BitDefender and Windows... Read more...
By now you've certainly heard of Microsoft Security Essentials (MSE), the free antivirus program hailing from Redmond and intended to replace Windows Live OneCare. Looking to capitalize on MSE's brand recognition, there's a rogue program making the rounds called "Security Essentials 2010." If the screenshot above looks at all familiar to you, then your system has been infected with a trojan called TrojanDownloader:Win32/Fakeinit. Microsoft describes this as a "fake scanner that informs the user that they need to pay money to register the software and remove these non-existent threats," but that's not all it does. It also terminates certain processes, alters the registry to cut off access to the... Read more...
Symantec has released a report (.PDF) on what it calls "rogue security software." According to the report, Symantec has detected over 250 distinct rogue security software programs, and during the timeframe of the report, July 2008 - June 2009, 43 million attempted downloads of such rogue programs. The company was unable to determine exactly how many installs completed. One of the most prevalent ways for these bogus AV programs to install is when a user browses to a website, which then pops up a message saying that "your PC is vulnerable," or "your PC is infected" or other similar warning. This type of scenario is an attempt to install "scareware" on a user's PC. If a user falls for the warning,... Read more...
While Symantec and other antivirus firms may make gibes at Microsoft's free Security Essentials antivirus, Microsoft reportedly offered the product in order to increase AV coverage in regions where people can't afford to pay for one. At least, that's the reason they gave, and at first glance it appears MSE is making some headway. According to Microsoft, in the first week they saw over 1.5 million downloads of Microsoft Security Essentials (MSE). At the same time, the company reported only 535,752 distinct PCs running the software (hey, where'd the rest go?). However, the companycounted four million malware detections on those machines, which is the main reason they released MSE anyway. so all... Read more...
Panda Security released the public beta of its Panda Cloud Antivirus today. The company claims this is the first free cloud-based antivirus thin-client. Panda Cloud Antivirus consists of a lightweight antivirus agent that is connected in real-time to PandaLabs’ Collective Intelligence servers. PandaLabs’ Collective Intelligence servers work to automate the malware protection cycle by collecting samples, analyzing, categorizing, creating detection and disinfection routines, and delivering protection to each node. The local portion of the Panda Cloud Antivirus requires about 50MB of hard drive space and consumes about 17MB of RAM. By the time Panda Cloud Antivirus exits the beta stage, Pedro Bustamante,...

Lavasoft, developer of the long-time entrant in the spyware detection arena, Ad-Aware, has released a stand-alone antivirus application. The new product, Lavasoft Anti-Virus Helix is based on technology from antivirus vendor Avira. It's interesting that Lavasoft would make this move shortly after Microsoft's announcement to drop OneCare and replace it with a simplified free product in the second half of next year. Additionally, the AV market is rather crowded, though obviously, the development of this product was long underway prior to the Microsoft announcement. Pricing is reasonable, with a 1 year license for $23.95. Multi-year and multi-PC licenses are available as well. Right now they also... Read more...
Besides ironic, what other words might come to mind over this, eh?The download section of AvSoft's S-cop Web site hosts the malicious code, according to Roger Thompson, chief research officer with security vendor AVG. "They let one of their pages get hit by an iFrame injection," he said. "It shows that anyone can be a victim.... It's hard to protect Web servers properly."The technique used on the site has been seen in thousands of similar hacks over the past few months. The attackers open an invisible iFrame Window within the victim's browser, which redirects the client to another server. That server, in turn, launches attack code that attempts to install malicious software on the victim's computer.The... Read more...
Windows isn't exactly known as the most secure OS at the moment, which is why Microsoft has gone to great lengths to improve all aspects of security in Windows Vista. Microsoft has coded Vista in such a way that traditional viruses would have a tuff time of compromising multiple machines, thanks in part to the new ASLR (Address Space [Layout] Randomization) feature. Though no system is perfect, Microsoft co-president Jim Allchin is still optimistic about the new security features found in Vista. "I'll give you an example: It's my favorite feature within Windows Vista, it's called ASLR (Address Space [Layout] Randomization). What it... Read more...
