Kasperky is good for many, and at the same cannot be so good for others. But anything that can support the needs for one's environment is always good.

By the way, please be constraint from posting activation keys that are not made available from the product providers themselves here. We frown upon such behaviours here at NBF.

http://antivirus.comodo.com/

Comodo is the only AV solution I use in a 5 computer household. Avira works well as does Avast. Have used both in the past. I cannot stand AVG or Threatfire. as Far as MSE goes, I was burned on my girlfriends laptop by MSE failing to catch a fatal virus and had to wipe and do a clean install . It may have been a fluke or just a missed definition update but I will stick with Comodo.

I was a Comodo fan for a long time until Vista came out. Had some bad run with some updates then I gave up. It is coming back with good versions lately I must say.

Ok but I think the key word you used is VISTA lol. I have only experienced Comodo with 7 but I have not had so much as a hiccup. I rely and trust it enough that I have disabled Windows firewall and user account control.
post #67 of 89
Yep - that was it, Vista We are on W7 now. I might giving Comodo a try again, being content with just Windows Firewall and MSE so far.

I think all the anti virus are really good but i am using Kasper Sky and its amazing to deal with just because it starts with the system and remove all the malware and trojen.

McAfee anyone?

I am glad that I stick with "free" stuff at least it would not "go berserk, freeze PCs"

Quote:
Computers in companies, hospitals and schools around the world got stuck repeatedly rebooting themselves Wednesday after an antivirus program identified a normal Windows file as a virus.

McAfee Inc. confirmed that a software update it posted at 9 a.m. Eastern time caused its antivirus program for corporate customers to misidentify a harmless file. It has posted a replacement update for download....
And more.

From the Engadget article on it, at least 90,000 computers were affected. That's going to cut into McAfee's market share...

Personally I think that this was a conspiracy since it seemed that the affected systems are on XP

New Malware Attack Renders All Antivirus Useless

"A group of security researchers say they've found a workaround for just about every antivirus product on the market today, effectively making Windows-based security programs totally useless.

Security research site Matousec.com recently issued an advisory for a process that allows malware to evade security detection. Note that this doesn't just apply to Microsoft's free Security Essentials software or other freeware antivirus products, but also targets full software packages from industry leaders like Norton, BitDefender and McAfee.

Matousec's Morphing Malware

According to reports, Matousec.com researchers compiled mock malware software with the capability of morphing its shape at any time. The trick? Once a security program discovers the problematic code, the specially-designed malware can actually switch out that code in order to infect the system.

The trick is called an "argument-switch attack," and makes catching viruses about as easy as pinpointing a shape-shifter in a crowd. The tactic is particularly successful on multicore processors, because one thread often fails to keep track of simultaneous threads. In the end, Windows PCs are tricked into allowing the infection to spread. (Source: eweek.com)

Thankfully, there are limitations to the exploit. An enormous amount of programming code must be loaded onto the victim PC for it to work. In addition, the attack appears to succeed only when the infected file is executed (launched / run) by a user on the selected machine (whether it's locally or by remote).

Attack Targets All Versions of Windows


The attack doesn't appear to play favorites across the various versions of Windows.

"The research was done on Windows XP Service Pack 3 and Windows Vista Service Pack 1 on 32-bit hardware," Matousec's report says. "However, it is valid for all Windows versions including Windows 7. Even the 64-bit platform is not a limitation for the attack." (Source: seattlepi.com)

Surprisingly, researchers say this flaw has been known for years, but that it failed to be fully addressed by security companies because no one seemed capable of taking advantage of the situation. However, as hackers grow ever wiser and their attacks become more sophisticated, the situation will be taken advantage of soon enough."

Bottom line? Watch where you click

From the article, it says it's virtually impossible on single-core machines and then the probability goes up the more cores used since it requires such pinpoint timing.

But also as they said, it requires the ability to run code on the machine directly, so if you "watch where you click" as Q said, it shouldn't be an issue.

MS actually does something well? I have been using MSE for many months now, having moved away from Avast, and happy with it so far.

Windows 7 'Compatibility Checker' Actually a Trojan

Windows 7 'Compatibility Checker' Actually a Trojan

On the same note of "warning" ...

Quote:
Beware any program that describes itself as a Windows 7 compatibility checker promising to verify whether or not your system can run Microsoft's new operating system (OS).

Prominent security firm BitDefender first reported the attack earlier this week, but noted that the problem has not yet become widespread. However, because the Trojan appears genuine, it could actually have an enormous impact on users in the near future.

Trojan Emulates Microsoft in Emails

As one might expect, scammers are using the popularity of Windows 7 to spread malware. "This [Trojan is in particular is appealing to many users] because of the interest in Windows 7," said Catalin Cosoi of BitDefender's Online Threats Lab. (Source: pcworld.com)

The Trojan, which arrives via email attachments, isn't accompanied by the standard awful grammar we've come to expect from these kinds of criminals. Instead, they've copied and paste actual Microsoft marketing text from the legitimate Windows 7 Upgrade Advisor page:

"This software scans your PC for potential issues with your hardware, devices, and installed programs, and recommends what to do before you upgrade," the fraudulent emails read.
Trojan Allows Hackers Free Reign

Those who take the bait and launch the email attachment will in fact initiate a file containing a Trojan horse called Trojan.Generic.3783603. Some may recognize the name from a Facebook password heist not long ago. (Source: theregister.co.uk)

Once the Trojan is installed, it installs a stealthy keylogger designed to soak up banking information and credit card data.

Of course, if you're looking for such a program that will determine if your computer can handle Windows 7, we recommend you go straight to Microsoft.com -- and never ever run a program included as an email attachment.

Microsoft released a core update for its Microsoft Security Essentials (MSE) today. Via Windows update!

And Avast, and AVG ... I wonder if these security people work on the same deadline

According to me Avast is Best, Because it start scanning through boot - sector.

So much for security with 64-bit OS

First rootkit targeting 64-bit Windows spotted in the wild

Quote:
Alureon rootkit is back, and has acquired the ability to hijack computers running 64-bit versions of Microsoft Windows, proclaimed Marco Giuliani, security researcher with security company Prevx.

Alureon (also known as TDL and Tidserv) has garnered a lot of attention back in February when it was discovered that it was behind the system crashes occurring after infected users tried to update their Windows OS.

It seems that at that point in time, the rootkit was unable bypass the security features that made the 64-bit versions of Windows Vista and 7 more secure than their 32-bit counterparts - namely the Kernel Mode Code Signing and Kernel Patch Protection.

The Kernel Mode Code Signing does not permit digitally unsigned drivers to access the kernel memory region (and kernel mode rootkits are often not), and the Kernel Patch Protection prevents kernel mode drivers from modifying sensitive areas of the Windows kernel. But, both protection mechanisms can be obviously bypassed by this new version of Alureon, which patches the Master Boot Record in order to intercept Windows startup routines and then loads its driver.

"The rootkit needs administrative privileges to infect the Master Boot Record. Even then, it still cannot load its own 64 bit compatible driver because of Windows's kernel security. So, the dropper forces Windows to immediately restart. This way, the patched MBR can do the dirty work," says Giuliani.

Well, Windows restarting "by itself" like that seems to me like a good sign to start worrying.

Giuliani also points out that this is not the first rootkit to be able to pass those security roadblocks - a bootkit named Whistler has been spotted being offered for sale on various underground markets some time ago - but this is the first time that the use of such a rootkit has been detected in the wild. According to him, the era of x64 rootkits has officially dawned.

Oh well, challenges, challenges

Microsoft will be offering in October 2010 its Security Essentials to small business / enterprises; meaning a free 10 licenses for server base.

This is about to make other security software screaming foul, for Microsoft is to undercut into their bread and butter (business environment).
