Odd things happen to laptop [Solved]
Posted 08 December 2014 - 03:37 PM
OK! Well done, your computer is clean again! Part of our jobs here at G2G is to help you clean your computer. But beyond that and just as important is to provide you with some information to keep you safe and secure on the net as well as to share knowledge. Following is that information.
1. Clean Up!
We need to remove all the tools that we used so that should you ever be re-infected, you will download updated versions which may have updated detection logic.
1. Download Delfix from here.
2. Ensure everything is checked.
3. Click Run.
Note: The program will run for a few moments and then notepad will open with a log. Please paste the log in your next reply.
2. Keeping Programs Updated
You need to ensure that any programs installed on your machine are kept current. The bad guys exploit vulnerabilities that are found in older versions of software. A very good piece of software that keeps your programs up-to-date is Secunia Personal Software Inspector (PSI). You can download and install it from here. You can read more information about this free software as well as a video walkthrough from here.
3. Keeping Java Updated (you are current so this is more of any FYI for future updates)
WARNING: Java is one of the most exploited programs at this time. The Department of Homeland Security recommends that computer users disable Java. You can read more about this here.
I would recommend that you completely uninstall Java unless you need it to run an important software. If you need it or are unsure or uncomfortable with removing it then I would recommend that you disable Java in your browsers until you need it and then enable it at that time. (See How to diasble Java in your web browser and How to unplug Java from the browser). If you don't uninstall it, it's also important that you follow the directions below to update to the latest version of Java.
1. Go to this page to download the latest version of Java SE Runtime Environment JRE 8 Update 25.
2. When you click this link you will need to click the "Accept License Agreement" radio button and then click on the "Windows x86 Offline" installer link. You will notice that there is also a Windows x64 link option, however even if you are using a 64-bit operating system, it's very likely you aren't running a 64-bit browser and should only download the "Windows x86 Offline" installer. To determine if you are using a 64-bit browser you can follow these instructions. If you find that you ARE using a 64-bit browser then you can download the "Windows x64" one.
3. Once you click on the appropriate link, please download this to your Desktop like we have with all of our tools.
4. Close any programs you may have running - especially your web browser.
5. Now we need to uninstall all versions of Java that are currently on your machine before we install the newest version. Go to Add/Remove programs (instructions are here) and uninstall any item that appears in the list that has the following as part of the name: (You are current at the present time)
6. Reboot your computer once all Java components are removed.
7. Then from your desktop, right click on the file that was downloaded (jre-8u25-windows-i586.exe or jre-8u25-windows-x64.exe) and select Run as an Administrator to install the latest version. Accept all the defaults and you're good to go.
Note: Java has been notorious for installing foistware (software downloaded without the users knowledge). If you follow the instructions I provided no foistware will be installed but that doesn't mean it won't in the future. While performing the install of this software or any software for that matter, pay attention to each screen and ensure you uncheck any extra software that you don't want installed (i.e. Ask Toolbar, Chrome Browser, etc.).
4. Keep Adobe Reader Updated
Check to see what the latest major version of Adobe Reader is here. The full version is something like 11.0.06 for example but the major version is just the first number before the period so 11 in this case or XI.
Verify what version you have by doing the following.
1. Open Adobe Reader
2. Click Help on the menu at the top
3. Select About Adobe Reader
If your major version matches the major version from Adobe then perform the following steps.
1. Open Adobe Reader
2. Click Help on the menu at the top
3. Click Check for Updates
4. Allow any Updates to be downloaded and installed
5. If asked to reboot, please do.
6. Repeat these steps until you are told that no updates are available.
If your major version is lower than the major version from Adobe then perform the following steps.
1. Uninstall Adobe Reader. Click here for instructions on how to uninstall a program.
2. Install the newest version from this website.
Note: Make sure to uncheck the Optional Offer (i.e. Google Chrome, Google Toolbar) unless you really want it.
1. Open Adobe Reader
2. Select Edit from the menu and select Preferences
4. Click OK and close the program.
NOTE: Many installers, including Adobe Reader, offer third-party downloads that are installed automatically when you do not uncheck certain checkboxes. While most of the time not being malicious you usually do not want these on your computer. Be careful during the installation process and you will avoid seeing tons of new unwanted toolbars in your favorite web browser.
5. Antivirus - Preventative
Note: Let's keep Malwarebytes installed as it's a fantastic piece of software. Malwarebytes is not actively monitoring your machine so it won't conflict with the Antivirus that you decide to install. I would recommend that you open up this program, allow it to update and scan your machine at least quarterly...monthly if you can.
6. Crypto Warning!!!! - Complete Data Loss can occur!
There are particularly nasty infections out there at the moment that encrypt your data and hold it for ransom. You may read more about this here.
New strains of this are coming out all the time. In fact a very new strain called VirRansom (which is a hybrid of CrytoLocker and CryptoWall) has recently been identified and it's a true self-replicating parasitic virus.
- Download CryptoPrevent free for home use here following the instructions below.
- Save the file to your desktop from the link above and then open the program by clicking Run when prompted from your browser or by going to the desktop where the file was saved and double-clicking.
- Accept all the defaults during the install. The last screen of the install has a checkmark in "Launch CryptoPrevent". This is good and will launch the program once you click Finish.
- You will get a prompt asking if you purchased a Product Key for Automatic Updates. You can answer No.
- You will then be prompted to learn more about automatic updates or if you want to purchase a key. This is up to you but you don't have to.
- You will then be prompted to apply all default protections. Answer Yes.
- You may get a message stating that Windows Sidebar and Desktop Gadgets are a major security vulnerability and asking you if you want to disable them. If you don't use these features, answer Yes.
- That's it. The protection is in place.
Note: The free version doesn't provide automatic updates. Periodically, you should open up the program (there is a shortcut on your desktop now) and select the Updates! menu....and select Check for Updates to see if there are any as this infection has serious consequences.
7. Adobe Flash Player
There's a very nasty piece of malware going around right now called Cryptowall. It's very destructive and most recently the newest variant is exploiting unpatched versions of Adobe Flash. Let's make sure you get current.
1. Determine if you have the most current version by going to this website. If your version represented by the top box matches the version in the bottom box you are current.
2. If your version is older than the current then click on the Player Download Center link (shown in the screen shot above).
3. You will be brought to the install/update page. Ensure you uncheck any optional offers (unless you want them of course) and then click on Install Now.
4. You may be prompted to run the installer. Go ahead and do this.
5. When it's complete, click Finish. You now have the latest version. You can verify by going back to this website if you feel the need.
