Wireless access slowed to a crawl on one PC

I believe the problems started about a month ago when i installed the Jump Desktop with TightVNC but that could be a coincidence. I've currently disabled Jump and TightVNC. My wi-fi access on my main machine has been getting slower and slower and, frequently, the Linksys USB adapter has to be reset or the machine rebooted to gain access. The problem isn't tied to a specific browser. It affects Explorer, Firefox and my default, Chrome as well as MS Outlook which downloads mail very slowly. The speeds do tend to vary. Sometimes it seems to speed up quite a bit but minutes later, it's back to a crawl.

Meanwhile, another desktop, my laptop, ipad, etc. all access wifi with no issues. Side by side speed tests with my laptop, sitting an equal distance from the router, gets 4+x the download and upload speeds of the PC and I'm not running the tests on both machines at the same time. The PC wasn't slow a month ago. I've got Roadrunner Turbo and usually don't have a problem. I've reset router and modem several times to no avail but the problem seems to be on this one machine. I've also made sure I have the latest drivers for my Linksys USB wifi connector as well as the latest flash updates for the router itself.

The PC has an Intel Core Quad CPU with 4gb of RAM and running Windows 7 32-bit. I have the paid version of Avast with the latest versions of the program and definitions set to do a full scan daily. Scans were showing that some files (mostly old backup files) were unreadable but this was in an external Maxtor drive that has been acting up (bad sectors, etc.) for some time. For the moment, I've disconnected it completely from the machine. Full scans with Avast, Super Anti-Spyware and Malaware Bytes in and out of safe mode have revealed nothing. I also ran chkdsk and scandsk in safe modeas recommended under the non-malware causes for a slow PC and my hard drives are set to defrag several times a week.

Thanks in advance for your help!

Bill

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Hello, have you tried to completely uninstall Tight VNC? What makes you think this problem is malware related?

regards, Elise

Hi Elise,

I was trying to think of new programs or events that coincided with the start of my internet connection problems and remembered I'd added TightVNC to work with the Jump desktop so I could access the machine via my ipad.

According to tightvnc.com FAQ page...

How secure is TightVNC?

Although TightVNC encrypts VNC passwords sent over the net, the rest of the traffic is sent as is, unencrypted (for password encryption, VNC uses a DES-encrypted challenge-response scheme, where the password is limited by 8 characters, and the effective DES key length is 56 bits). So using TightVNC over the Internet can be a security risk. To solve this problem, we have plans to implement built-in encryption in future versions of TightVNC.

In the mean time, if you need real security, we recommend installing an SSH server, and using SSH tunneling for all TightVNC connections from untrusted networks.


I haven't uninstalled it as I'm not sure I even have a problem.

First I changed my router password in case I had a neighbor hijacking a signal. That made no difference.

I'd read that an overheated router could cause this problem. The Linksys G router was fine with wired connections, I could watch streaming netflix, for example and I had no speed problems with my Dell XPS attached wirelessly but my 2nd desktop machine was having similar speed issues. 12 mbs at times and less than 2mbs ten minutes later. My main PC had similar speed issues and was constantly needing to either reboot or reset the wireless adapter.

My router was in a stack with an old model Apple TV and the modem and was hot. I swapped it out with another Linksys N router. I haven't seen speed or connection issues since then.

Thanks,

Bill

So, if I read this correctly, you do not have any issue at this point?

Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system.
  • Download the latest version of Java Runtime Environment (JRE) Version 7u2.
  • Look for "JDK 7u2 (JDK or JRE).
  • Click the "Download JRE" button at the right.
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
    • Select "Windows x86 Offline" and click on jre-7-windows-i586.exe
  • Save it to your desktop
  • Close any programs you may have running - especially your web browser.
  • Uninstall all older versions of Java (any item with Java Runtime Environment, JRE or J2SE in the name).
  • Reboot your computer once all Java components are removed.
  • Install the newest version by double clicking (run as Administrator for Windows Vista/Seven) the downloaded file.

regards, Elise
