It appears that today is anti-malware-day on kkomp.com: So I’ve written a bonus article, because I really do recommend that you use this free software: -

As you may or may not know, I’ve been plagued with viruses over the last few days. Fortunately the infection has now been dealt with; thanks to Microsoft Security Essentials. When I became infected, my antivirus solution provided by Avast! simply didn’t see it. Malwarebytes was oblivious to it also. – Yet there was definitely an infection, as my system was spewing out spam emails to all on my contacts-list, as well as to non-existent addresses that the worm was probing by creating the address itself and seeing if the mail was delivered.

AdAware from Lavasoft managed to find a keylogger, a backdoor Trojan, and the worm itself. I thought that the problem was sorted at that point, and went merrily on my way singing joyfully and blogging crazily. The following day I activated my email client, then switched on the 64-bit box, as well as the external hard-drive. My email inbox was soon swamped by hundreds of “Message Undeliverable” emails. The worm was back!

How? I cleaned both boxes with AdAware, I formatted the external hard-drive, including all the backups, and made a fresh backup. Nevertheless I did it all again, and the system stopped sending spam. I ran 4 different programs on all drives of both machines. All reported that the system was clean. Imagine my horror when two days later the system started sending spam again!

I’d recently been reading an article on PC Mech.com, entitled “Free Anti-Virus From Microsoft Is Now Available”. This gave me an idea: Microsoft earlier dropped its Windows One-Care program, and promised to replace it with something a bit lighter. This was the promised product; just out of beta.

My thinking started to run along the lines of: “Well it’s a new antivirus solution, it’s from Microsoft, it works with Windows 7 64-bit as well as with Windows XP 32-bit; both of which I run, and it’s best of all FREE, which means that it won’t hurt to give it a try. – There’s definitely a problem somewhere on my system that everything I’ve tried so far is missing; so let’s give it a whirl.”

I isolated the box running XP 32-bit, removed Avast! free-edition from it, and installed Microsoft Security Essentials. I set it to auto scan in 1/2-hour . To cut a long story short it found 4 pieces of malware, which it rated as a severe threat, and removed them. Upon reconnection; after I’d isolated the Windows 7 box, having installed Microsoft Security Essential on it, no spam. Yay!

I ran it on the 64-bit Windows 7 box. – It found the culprits: Two instances of Trojan downloaders: ASX.Winmad.AN, and ASX.Winmad.CJ. It deleted the infected files, which had been downloading various malware infections and distributing them over my LAN. – Target neutralised: I’m now virus free.

I can’t speak too highly of Microsoft Security Essentials. It’s a glowingly-excellent piece of software from the softies. Microsoft Security Essentials was the only free antivirus solution that was able to both see and clear the entire virus-infection and fully clean my system. Most other solutions couldn’t see any infection at all, and those that did didn’t get to the root of the issue. Microsoft Security Essentials, however, did the business and completely solved the problem.

After that glowing report, let’s get back to reality with the nitty-gritty: -

Microsoft Security Essentials is extremely thorough: On its default setting it scans everything, and I mean everything. It looks inside zipped archives; personal, program, and system archives, byte by byte: .CAB files and the like are no longer safe places for malware to hide. If it does then it will die by being detected and eradicated bit-by-bit.

Being so thorough; there are obviously limiting factors.

The first of these is time: Microsoft Security Essentials is fast; there’s no doubt about that, but it does so much work that it’s no faster than any other antivirus solution of a similar type. I found that on my box running 64-bit Windows 7 with a 3-core AMD Phenom CPU running at 2.3GHz and 8GBs DDR2 800MHz RAM, Microsoft Security Essentials managed to scan about 50 GBs of data an hour.

The second is heat: With such a colossal amount of calculations being processed at a quite incredible speed, the processor would have a lot of work to do, and therefore produce heat. This antivirus solution, running a full scan, is no laughing matter. I have a feeling that a single-cored processor of 1.8GHz or less would have problems with it. Indeed, from personal experience, I had a lot of programs running at the same time as the full-scan was happening on my AMD Athlon 64×2-powered box, running 32-bit XP Professional at 2.3GHz with 2GBs DDR2 667MHz RAM, and the processor usage went so high for so long that the thermal-trip shut the CPU down before it fried. Running Microsoft Security Essentials on its own caused no such problem though, and the scan was slower than on the 3-core Phenom, but totally effective nevertheless.

As you’ll see from the white CPU-usage graph in the top-left corner of the picture of the readout from Glint system monitor, above, the processor usage can be quite large. This readout was from the Athlon 64×2 XP box with only Microsoft Security Essentials running.

One other thing: If you’re running 64-bit XP; and that’s probably not a lot of you, as 64-bit XP can be a nightmare as far as drivers are concerned, there’s no version of Microsoft Security Essentials for your operating system. Microsoft Security Essentials has versions for 32-bit XP, 32-bit Vista and Windows 7, and 64-bit Vista and Windows 7.

Have you tried out Microsoft Security Essentials yet? If so then what do you think of it?

Being a geekette; that is a female computer designer/builder, as well as a blogger, I often get asked by my girlfriends (And some of their boyfriends too – Shh!) to pop over for a cuppa and attend to some problem they’re having with their computer. Most of these problems turn out to be software-related, so it’s always a good idea to come prepared – Although I can download most of what I need from the internet, sometimes their internet connection is not working for whatever reason, and more than one is on dial-up – Which can make downloading a program a 2-hour job in itself.

To combat this I have a 1Gb USB flash drive with most of anything I might need on it; plus loads of links to anything useful on the internet itself that might be useful which I haven’t bothered to include because I probably won’t need it.

I pop the cord from which the USB stick hangs around my neck, and go to sort out their issues.

I mainly have program installers in the form of .exe files on the USB drive: These are always useful. I also am able, in a worst-case scenario, to provide them with a temporary internet connection via my mobile device, for which I also carry a USB bluetooth dongle to plug into their computer on the rare occasions where it is necessary; such as an instance a year plus ago where a friend somehow lost the driver for their network interface device and was unable to communicate with their router as a result: I removed the old driver which was faulty but obviously didn’t have that particular driver on the USB device; so I set up a temporary internet connection via my mobile phone/bluetooth and downloaded a new driver, installed it – Target neutralised.

The items I have on my USB drive are listed below: I’m sharing this with you as I’m assuming that as a geek you too get called out to similar situations; but being unable to fix it on the spot you end up taking their computer home, doing the work in your spare time, and returning their computer at a later date; which causes inconvenience to both parties.

The files I carry around on my USB device are as follows:

1. AVG Anti-virus.exe installer: You’d be mightily surprised how many people don’t run an anti-virus program! They might find that their computer slows down with use; and, not realising that it is caused by the registry getting cluttered with crap among other things, they start removing programs which they think are unnecessary in order to attempt to get the machine to speed up again, one of those “unnecessary” programs being their anti-virus program.

2.. A free anti-spyware program; such as AdAware and Spybot Search and Destroy – For the reason stated above or that they didn’t even know what spyware was etc. The latest AVG antivirus has built-in spyware-protection, but that protection is not exhaustive, so it’s always a good idea to install extra spyware protection supplemental to that.

3. Free FTP clients in .exe installer format, such as WS-FTP-LE and FileZilla: They do occasionally come in handy.

4. Diagnostic programs; such as Core Temp.exe, Diskcheckup.exe… I know; rather than listing them all here I’ll show a picture of all the icons below and to save a lot of my time I’ll let you Google for them all.

Obviously the folders are of my own making: Batch Files contains some useful batch files that I wrote or copied, Dragons Websites contains the URLs of the websites of the millionaire entrepreneurs from the BBC series “Dragon’s Den”, Glint(Program) contains the .exe file of the Glint System Monitor program, KK contains pictures which I use regarding Kustom Komputa; Suppliers, Parts, and Circuits contains URLs to suppliers of computer hardware components, plus a few electronic circuits, Web Shortcuts contains hundreds of various useful URLs, Websites contains copies of all my website files from some of my various sites, WP Plugins contains some useful WordPress plugins. Some of the files, such as DSC00* are photos from my mobile phone. aports.zip shouldn’t be on there as it’s a program that contains malware. OEM Exel and OEM INXP are folders containing branding files which I add to the OS to indicate that I am supplier, builder, and maintenance tech for a particular computer. The file “Kustom Komputa” is a copy of some files from my Kustom Komputa website. WP Themes contains WordPress themes. The Folder “Self-Installing Scr” contains a number of screensavers that I created and which automatically install on the computer upon activation of the .exe file thereof. (No malware involved.) The folder Paint.net contains the program Paint.net, and the folder “Sounds” contains some alternative Windows sound effects as spoken by the Daleks from the BBC TV series “Dr Who”.

There are also a number of shortcuts which you don’t normally see on any Windows desktop. These shortcuts; such as “Sound Recorder“, “Volume Control“, “Command Prompt“, “Device Manager“, and “Sleep or Hibernate” are described on this site, including the method to create your very own icon(s).

So that’s pretty much it: Carry this lot plus your own personal files around on a USB flash drive and you won’t go far wrong.

HTH (‘Hope That Helps.)
