How to do a Tune-up/Clean-up with Virus Scans for your PC!

General PC Tune-up/Virus Scan Procedures:

Uninstall/Install Software:

  1. Uninstall Obvious Bloatware:
    • “Free Trial” software
    • Obvious junk programs & toolbars (One Search, Driver Support, One Bar, etc)
      1. Use the PNW Computers “Browser Hi-jack” blog article as a reference to find and remove software malicious Adware Programs.
      2. Computers that are heavily infected should be checked with ‘TDSKiller’ to rule out the presence of a Rootkit BEFORE any cleaning procedures begin. Unless cleaning is needed to run the utility.
  2. Install/Update Essential Programs:
    1. Security Clean-up Software List (Ninite.com can be used for installing most apps):
      1. Chrome, Firefox, Edge - Update
      2. Java, .Net & Silverlight Runtimes - Update/Install
      3. Malwarebytes Antimalware
      4. Malwarebytes ADWCleaner
      5. BleachBit

Security Scanning & Virus/Malware Removal:

  1. Virus and Malware Scanning:
    Run FULL (not a quick/fast) Virus Scan with Local AV as well as Malwarebytes and ADWCleaner

  2. Web Browser Clean-up:
    • Check all Installed Web Browsers’ Extensions/Add-ons for anything unwanted/needed.
    • Check the general browser settings (Start Page, Default Search Engine, Etc.) for any tampering or modifications and reset to defaults if needed.
    • ADWCleaner is an excellent tool for finding and removing browser hijack apps.

Performance Tune-Up:

  1. Junk File Clean-up - Bleach Bit

  2. Paging File Optimization

    1. Set the PC's paging file to either 1.5 the amount of RAM or set to 4096MB.
      1. Settings > System > About > Advanced System Settings
        1. Select the “Advanced” tab at the top
        2. In the “Performance” section click on “Settings”
        3. Click on the “Advanced” tab
        4. Under “Virtual Memory” click on “Change”
        5. Set the paging file accordingly

  3. Optimize System Performance Options

    1. Right-click ‘My Computer’ > Properties > Advanced System Settings> Click ‘Advanced’ tab > Click ‘Settings’ under the “Performance” area.
    2. Un-check all of the PC's visual effects performance options except for:
      1. "Use visual styles on windows and buttons"
      2. “Smooth Scroll List Boxes”
      3. “Smooth Edges on Screen Fonts”
      4. “Show Translucent Selection Rectangle”
      5. "Use drop shadows for icon labels on the desktop"
      6. Start-up Program Entries can also be managed using the Task Manager.
      7. Disable all unnecessary start-up items
        1. Typically leave start-up programs related to:
          1. OneDrive/MS Office
          2. iCloud Drive
          3. Printers
          4. WIFI Software
          5. Audio/Video Software
          6. Specialty apps such as Garmin, Fitbit, etc

Windows Updates:

  1. Access Windows Updates through System Settings
  2. If the Microsoft Update feature is not/has not been enabled, enable Microsoft Updates in the Windows Updates “Advanced Options”. You can also enable the “Notify me when a restart is required” option too as well.
  3. After the Microsoft Update feature has been enabled, Windows Updates will now check for both Windows and Microsoft Updates.
  4. Allow the computer to check for new updates.
  5. Once checking for updates is finished, download and install all available updates.
    1. You may need to do this process more than a few times to make sure the system is fully updated.
  6. Some Windows Updates may fail. Do not hyper-fixate on failed updates, as they will likely resolve on their own after a few update/restart cycles.
  7. Verify Installation of all currently available Windows Updates AND Upgrades

Security Software:

What is a rootkit!? A rootkit is a program or a program kit that hides the presence of malware (or itself) in a system. A rootkit for a Windows systems is a program that penetrates into the system and intercepts the system functions; Windows API. It can effectively hide its presence by intercepting and modifying low-level API functions. Moreover it can hide the presence of particular processes, folders, files and registry keys. Some rootkits install their own drivers and services in the system and they also remain “invisible".

Ransomware; What You Need To Know


With the popularity of the "WannaCry" ransomware bug that went around in early 2017, most folks are pretty familiar with the term Ransomware (aka an extortion virus). If you are not familiar with term, essentially a Ransomware virus is bug that usually gets into a system through an infected attachment via a fake Email. Once the email is opened, the virus activates and immediately starts to seek out and encrypt Word Documents, Excel Spreadsheets, Pictures, Music; anything it can get it's hands on. It is a VERY destructive type of attack and if not prepared, you could loose all of the precious data that is stored on your computer and connected to your computer!

So what is Data Encryption?

Data encryption is a way to lock a file, or any type of data on a hard drive, very securely. Encryption essentially locks a file with a nearly unbreakable secret password, key, etc. Once a file has been "locked" or encrypted, you need have to have the secret key or password to be able unlock and access file(s) again. The key or password is what enables you to decrypt, or "unlock" the file, and have access to all your stuff again; pictures, documents, music, etc. So what the scammers are trying to achieve with deploying Ransomware is to lock your data up and then extort money from you to get your data back. Essentially make you pay a ransom to get your data unlocked and accessible again.

What can you do to protect yourself from Ransomware attacks?


  1. BACKUP YOUR DATA: Back up your files remotely every day, but only on a hard drive that is not connected to the internet. So long as you back up files on an external hard drive, you won’t lose any information if hit by a ransomware attack.
  2. NEVER OPEN A SUSPICIOUS EMAIL ATTACHMENT: And never download an app that you haven’t verified with an actual store. Read reviews before installing programs.
  3. SCAN ALL DOWNLOADS: Some antivirus programs have the ability to scan files to see if they might contain ransomware. Make use of them before downloading any questionable attachments from email or software from the internet.
  4. EXTRA PROTECTION: If you want take things a step even further, BitDefender does have an Anti-Ransomware security tool you can install and run on your computer to supplement (and work in conjunction with) your existing security software:
    www.bitdefender.com/solutions/anti-ransomware-tool.html

What do you do if you have already gotten infected with Ransomware?

If your computer has been attacked by ransomware, you can explore the free ransomware response kit (from ZDNet) for a suite of tools that can help with a ransomware attack.
Pacific Northwest Computers also recommends the following to moderate an attack as well:
  1. Remove the infected machines from the network, so the ransomware does not use the machine to spread throughout your network!! VERY IMPORTANT!!
  2. Decide whether or not to restore from available backups, try to decrypt the encrypted data, or pay the ransom and take it as a lesson learned.
  3. Research if similar malware has been investigated by other IT teams, and if it is possible to decrypt it on your own. About 30 percent of encrypted data can be decrypted without paying a ransom. Some of those tools are listed below:
If the none of the available decryption tools work (or a decryption tool is not available for your specific type or Ransomware) data recovery could be a last resort option. There have been cases where when the Ransomware virus attacks and the data encryption first occurs, the original file is actually copied and then deleted, and the copied file is what gets's encrypted! So we can try to recover those original files!

If you have been hit by a Ransomware virus, you need Ransomware Data Recovery, or you are interested in getting some systems in place to be prepared and protected in the case of a Ransomware attack, feel free to reach out to us!

Security & Performance for your PC!!

I get asked all the time, “Jon, what do you recommend for security and performance for my computer?” So I decided to give folks a brief, and to the point, run down of what I programs and tools I use and recommend.

So, core security: I typically use and install Avast Free or BitDefender Free Antivirus (MS Security if Windows 7). Then I always use (and have used for years) MalwareBytes Antimalware and Spybot Search & Destroy. MalwareBytes is a Zero-day exploit and “name brand” bug catcher King and Spybot can find a lot of stuff that normally would get left behind and can also undo damage a virus has caused to your system. But you do not want them to be running all the time, as your Antivirus is providing that protection. MBAM (MalwareBytes for short) and Spybot are just "tools in the toolbox" per say. Include them in your routine scans and cleanings but they will be your go to, if and when a virus gets around your Antivirus. But the basic "run it when you need it" free versions are all you need (unless you have computer with horsepower and speed then let em rip!).
Then with the new variant of malware being “browser hi-jack” bugs, if you get hit with something like that, all those other security programs may not be able to find all of them; or even any of them at all! So that is where ADWCleaner and JRT come in to play. Both are now distributed by MalwareBytes (so that's who you will likely download them from as an FYI), they are specifically browser hi-jack clean-up tools. These tools will find, fix and remove what the other programs cant. Including website re-directions, search engine and homepage hi-jacks, removal of malicious add-ons, and much more.

Then last but not least, lets keep the computer clean of junk!

Class, meet CCleaner. CCleaner; class.

CCleaner has been my go-to performance and clean-up tool for nearly my entire professional computer career. Junk, temp and cache files, prefetch data, DNS cache, delete free space; CCleaner can do A LOT! So to keep things clean and your computer running snappy, I highly recommend it’s installation and use!

You can find direct download links to all the previously mentioned programs, as well as a complete virus removal tutorial just by clicking the link below! Doesn’t get much easier than that ;)

As always, if you need any kind of computer or “tech” help, or if you have any questions, feel free to get in touch! This is why I do, what I do :)
