I have 6000kbps broadbrand and a router i'm on cable not wifi.
I use Vista and have a Toshiba P200 laptop with around 3Gb memory

This problem is very anoying after Pc been up for some hours the Browsing become very slow
Opening a IE7,Firefox or any browser windows can take a while
also opening a new tab or even browsing from page to page can be slow.

Its like the page is routed through something slowing it down.
sometimes a reboot fixes this.

I made a video of when it happen
this video dont show the worst sometimes it take way longer to open a page:


Im using Kaspersky antivirus 2007 but I turned internet protection and proactive protection off and it still happen
I also have Zonealarm free (but with Pro i also had same problem)

I am begining to think there is Malware or keysniffer hiding somewhere.

I have had this problem on other Pc i just store all my stuff on a External hardisk have stuff there that is like 8 years old
I noticed the problem arise after a week or so after a fresh format make me think can come from some of the old backed up files
i drag over.

I have scanned for viruses with Kaspersky antivirus , Panda online scan and Spybot and found nothing.

There is another issue here

Most of the program (.exe files in use) want to have acess to internet through my firewall
even the Audiovolume icon want to have acess to internet (what do a Audioicon need acess to internet for)

crrss and svchost ask also for internet conexion many time with higher ports between 40000-50000

Googleupdate and conime.exe are often silently running in the background.

And sometimes i get an Security option error when clicking ctrl+alt+del not letting me view program in background
this happen not very often now but happened all the time with Zonealarm pro so i uninstalled it and installed zonealarm free
then i didnt have this problem for sometime until it started apearing again but not so often as before.

I suspect some malware is trying to use legitable .exe and .dll files to conect to internet and hence slowing down browsing.

I would be thankful if anyone could help me with this problem

I am probaly going for another format next week (just 3 weeks since last format)

Had a lot of problem with Slowdown after installing vista Sp1 so i unsintalled it and dont plan install it again on this laptop
i probaly just wait for Sp2.

But for now i like to find out where the problem is.

2 years ago i was infected with a virus called Virut.A (or something) that infected most of my .exe files
however i have scanned files on external hardrive and Dvds and this virus is not there
but maybe there can be some rest of it or something else that is still causing headache to my pc.

I cant just Format and not backup files i have since i need them
atleast the music and photos i need.

If you use Spybot's Teatimer function, disable it for now
------------------------------------

The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
