Malware Herd Protection For Your PC

TCAT Shelbyville IT Department:

Excellent find…Rick you are awesome!

Originally posted on What's On My PC:

What is that old saying, “there is strength in numbers?”… Malware is the leading cause to computer problems today that is also criminal in nature. What I have discovered over the years that no single anti-malware or anti-virus program can give you protection 100 percent of the time.

This is where the cloud sourced program called herdProtect can help, as your second line of defense against malware, by providing strength in numbers. herdProtect utilizes a ‘herd’ of multiple online anti-malware engines (68 engines to be exact) to guarantee the widest coverage and the earliest possible detection. As a second line of defense anti-malware solution, herdProtect is designed to run with any existing anti-virus program already installed on a user’s PC. herdProtect is a free service to help user’s find and remove malicious software; and, is an excellent resource to run, after an infection, when you think you have…

The 60 GHz Wi-Fi technology will enable a 1 gigabyte movie to be transferred between devices in less than three seconds…read more

Using a GPS to perform a Wi-Fi survey

It is important to perform a wi-fi survey so that you can determine not only the perfect place to locate your access point or bridge but to gain an understanding of the channel co-existence challenge you may face.  With wireless access points in surrounding neighborhoods and businesses, you will need to  perform a survey by walking around and mapping out the BSAs (Basic Service Area) of wireless that surrounds you and your organization.

Below is an example of our school’s perimeter.  Matt, Chris and James, students in the Computer Information Technology, class performed a survey using a Microsoft GPS and Vistumbler.  This survey revealed access points and their channels of current wireless at our institution and  includes APs in surrounding businesses and neighborhoods.  These were mapped using Google Earth after exporting their KML file from Vistumbler.

This type of survey allows IT professionals to analyze data exported to ensure the correct channels can be used at their organization.

Miller Goodroe Felts

After exporting the wireless information, you can analyze each access point or wireless device by clicking on it.  Below is an example of the information exported into Google Earth.   Each device shows SSID, Network Type, Mac Address, Channel, Security, Encryption Type, Data Rates, Latitude, Longitude and Manufacturer information.   Analyst using this information can also determine the best placement of wireless devices along with channel information.

ESSID Expanded

Channel co-existence is when access points share channels that are very close to one another.

802.11 wireless on 2.4 Ghz has three non-overlapping channels.  These channels are 1, 6 and 11.  The closer channels are, the more likely interference will take place.  With the amount of wi-fi in use today, IT professionals have to chose between 2.4 Ghz and 5 Ghz and and try to select channels that are not in use if possible.   Professional access points and bridges can also adjust power as necessary.   A dense population can make this very challenging.

If you look at the students’ survey by zooming out to see how many access points can be seen, this is what you are looking at!  Now you can see why site surveys are important at your organization.

In addition to this survey, a secondary survey using a spectrum analyzer is very important to search for interference from other sources.  (See our review of the Airview Spectrum Analyzer)

What about caching programs to speed you up even more?

I’m always cautious when I hear about caching programs.  Mickey sent me Bill Mullin’s link over to TechRepublic where Romex’s FancyCache is reviewed.

In its Beta release, FancyCache offers a simplex program that uses unused memory to boost the speed of your hard drive.  But does it work?  Yes.  My Dell Inspirion is already fast, but with FancyCache, programs do open quicker and the computer is even more responsive.  With the ability to tweak how I wanted to cache, I used 2gb of the 6gb of RAM on board in the settings.

The default settings alone were convincing enough to show how my computer sped up after a few minutes of use.   Although my computer is a 64bit laptop, the caching methods used and the read/write cache algorithms did boost performance.

FancyCache is certainly beneficial for 32 bit users who are locked in at 3gb of RAM.   FancyCache can take advantage of memory above this limit to speed up your computer.   And whether you do or don’t elect to install FancyCache, at least tweak your settings in a 32 bit computer to tweak your memory.  (See our Link)

The only problem I had was once I downloaded the software, it said it was expired.   A quick check on their website and keys can be obtained here.   The latest key is valid until July 2013.

Will I buy this product?  I’m not sure yet, time and use of Fancycache will tell.

What If I Have a SSD Drive?

Have you recently purchased and cloned your old HDD with a new SSD?  Here’s some tips. (Updated!)

  • Make sure your SATA controller is set to AHCI mode.
    Set AHCI mode in the BIOS if this is not enabled and make changes to the registry (first)
    AHCI is needed for native TRIM support in Windows 7.  This allows TRIM to do its job

Device Manager

  • Click on the Start
  • Control Panel
  • Device manager
  • IDE ATA/ATAPI controllers
  • Do you see the AHCI controller?

How do you enable AHCI?

Before doing the process below,  see if your BIOS has AHCI capabilities (Windows 7)

  1. Open Registry Editor and move down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci.
  2. Right click on the Start DWORD and click on Modify.
  3. Set the value to 0 and click OK.
  4. Reboot your computer and enable the AHCI setting the BIOS.  Another restart will be required to finish the driver installation.

 

The next step is to enable TRIM. Type the following command in a command prompt to enable TRIM:

fsutil behavior set disabledeletenotify 0

Next, turn off Defragmentation.  These drives should not be defragged.

Next, turn off indexing.  This causes unnecessary writes.

Next, Click on Start  -Right-Click Computer – Manage – Services and Applications – Services -Right-Click Windows Search – Properties  Find the Startup type – Select Disabled – Click OK.

(The above disables the “search indexer”)

Windows Search

Next

Click on Start – Computer – Right click on your SSD – Properties – Uncheck Allow files on this drive to have contents indexed in addition to file properties – Click OK.

Drive Index

Next

  1. Right Click on Computer and select Manage
  2. Click on Device Manager
  3. Expand Disk Drives
  4. Right click on the hard drive and select Properties for that hard drive (you can also double click the drive
  5. On the Policies tab:
    Check Turn off Windows write-cache buffer flushing on the device
  6. Hit OK and close the Device Manager

Next, if you have 6 GB of RAM or more, disable the page file if it is the only drive.  If you have a second drive, point the Paging file at the other non-SSD drive

Finally disable Superfetch and Prefetch on the drive (Official Microsoft Article)

Click on Start Menu – Right-Click Computer – Properties – Advanced System Settings – Advanced Tab – Performance Settings – Advanced Tab – Click Change under Virtual Memory – Uncheck Automatically manage paging file size for all drives – Click on No paging file – Click Set – OK – Restart your computer. (Always check your pc to see if the 6 GB or more is OK. This will be based on programs that are running)

Check for the latest firmware!

SUMMARY

Load Windows Server or Windows 7 on the SSD drive.  Optimize the SSD and complete these actions.

  • Open a command prompt and “Run as administrator”. Next, type in the command “Fsutil behavior query disabledeletenotify”
    This will take care of TRIM
  • Don’t defrag the drive (SSD)
  • Turn off indexing
  • Disable Superfetch and Prefetch on the drive (Official Microsoft Article)
  • Move the pagefile to one of the mechanical drives
  • Install programs to other drives on Windows Server
  • Small databases such as Quickbooks or Access databases can be used on the SSD 
    (If you have thousands of logins to your shared database daily, consider moving the databases to one of the storage drives)
  • Ensure your computer has AHCI enabled in the BIOS AND in the Registry (Make sure you enable in the registry first AFTER verifying your BIOS supports AHCI)

While you’re at it, optimize your CPU

Partition your hard drive for optimization

Gamers and IT professionals along with home users that are power users can significantly improve HDD performance by shrinking the partitions on their HDDs.

By using the Disk Management utility in Windows you can shrink large HDDs as needed to increase performance.

How does this work?

For optimal system performance on an IIS server, you should install Windows and IIS on one drive and data on another drive.  When you install Windows, you can partition the entire drive with the full amount and use disk management to shrink the drive later OR you can give yourself enough space +30% for temp files (etc.).  By shrinking the drive, this optimizes the drive by not only placing files where they should go but allows the drive to become efficient by having only a certain amount to index and read.

The same should be done for the data drive.  You can extend the partition as data grows and space is needed.

Hopefully my math is right on the percentages…

Notes:

Partitioning SSD drives will show a gain, but because of the economics behind SSDs at this time, it may not be economically feasible.  SSD drives can be optimized in other ways.

Linux and Apple drives can be optimized by partitioning.

Golden Rule – Do not use the unallocated amount.  Save it for growth or files that are not accessed often.

How to Shrink or Extend a partition

Over-provisioning is the allocating of a specific amount of free space on your SSD.  Over-provisioning improves SSD endurance and performance.   Many SSDs are packaged with software that helps the end user install the drive and to plan for OP.  (More advanced drives are doing away with OP).

The SSD controller manages all of the data that is stored on the drive.  While these drives are really fast, data writes are not just placed on the drive.  Data is moved around and the controller on the drive is programmed to use the drive evenly across the NAND blocks.   By moving the data around, the controller can use the free space (OP) to swap information as needed.     This in turn adds life to your SSD.  Always update your SSD firmware, use the manufacturer’s software for OP if your drive recommends it and don’t forget to trim your hard drive.  TRIM allows for the removal of junk or old data.  How? Easy – Open a command prompt (as Admin)

Type the following – fsutil behavior set DisableDeleteNotify 0
