I recently allowed my cousin to borrow my labtop. But I think they may have visited some bad websites. My labtop has been very slow to respond since they used it. And when I try to use a web browser it takes me to websites I did not click. My sister has tried to help me by removing my internet cache with CCleaner. And by running McAfee antivirus to check for viruses. The antivirus didn't find anything wrong. So she deleted some programs I wasn't using. Then she changed my advanced system performance settings to lower my memory usage with visual effects. I don't know a lot about computers. But I think there may still be something wrong with it. How do I check to make sure? I'm using a dell labtop with windows 7.

Please download and scan with the Kaspersky Virus Removal Tool from one of the following links and save it to your desktop.Be sure to print out and read the instructions provided in:How to Install Kaspersky Virus Removal Tool
How to use the Kaspersky Virus Removal Tool to automatically remove viruses
  • Double-click the setup file (i.e. setup_9.0.0.722_22.01.2010_10-04.exe), select your language and install the utility.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If you receive a UAC prompt asking if you would like to continue running the program, you should press the Continue button.
  • At the 'Setup page', click Next, check the box to accept the license agreement and click Next twice more to extract the required files.
  • Setup may recommend to scan the computer in Safe Mode. Click Ok.
  • A window will open with a tab that says Autoscan. Click the green Start scan button on the Autoscan tab in the main window.
  • If malware is detected, you will see the Scan Alert screen.
  • Place a checkmark in the Apply to all box, and click Disinfect if the button is active.
  • After the scan finishes, if any threats are left unneutralized in the Scan window (Red exclamation point), click the Neutralize all button.
  • Place a checkmark in the Apply to all box, and click Disinfect if the button is active.
  • If advised that a special disinfection procedure is required which demands system reboot, click the Ok button to close the window.
  • In the Scan window click the Reports button, choose Critical events and select Save to save the results to a file (name it avptool.txt).
  • Copy and paste the report results of any threats detected. Do not include the longer list marked Events.
  • When finished, follow these instructions on How to uninstall Kaspersky Virus Removal Tool 2011.
-- If you cannot run this tool in normal mode, then try using it in "safe mode".


Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
  • Double-click on the renamed file to install, then follow these instructions for doing a Quick Scan in normal mode.
  • Don't forget to check for database definition updates through the program's interface (preferable method) before scanning.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues.
Malwarebytes may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • After the scan, make sure that everything is checked and then click the Remove Selected button to remove all the listed malware.
  • When done, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab .
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows the database version and your operating system.
  • Exit Malwarebytes when done.
If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

Note: A 14-day trial of Malwarebytes Anti-Malware PRO is available as an option when first installing the free version so all users can test the real-time protection component for a period of two weeks. When the limited time period expires those features will be deactivated and locked. Enabling the Protection Module feature again requires registration and purchase of a license key that includes free lifetime upgrades and support. If you continue to use the free version, there is no requirement to buy a license...you can just use it as a stand-alone scanner.

Try doing an online scan to see if it finds anything else that the other scans may have missed.

Please perform a scan with Eset Online Anti-virus Scanner.
  • If using Mozilla Firefox, you will be prompted to download and use the ESET Smart Installer. Just double-click on esetsmartinstaller_enu.exe to install.
  • Vista/Windows 7 users need to run Internet Explorer/Firefox as Administrator.
    To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser and allow the download/installation of any require files.
  • Under scan settings, check Posted Image and make sure that the option Remove found threats is NOT checked.
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • Click the Start button.
  • ESET will install itself, download virus signature database updates, and begin scanning your computer.
  • The scan can take some time to complete...close all programs and do NOT use the computer while the scan is running.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply. If no threats are found, there is no option to create a log.

Note: If you recognize any of the detections as legitimate programs, it's possible they are "false positives" and you can ignore them or get a second opinion if you're not sure. Eset's detection rate is high and can include legitimate files which it considers suspicious, a risk tool, a potential unwanted program or a possible threat.

I've been trying to scan with ESET since yesterday, but it gets a "unexpected error". I am trying the scan again, I'll let you know if it finishes.

I've started running the scanner, which I'm going to leave on overnight. And I'll be posting the results of the log tomorrow.

So, if my labtop does not have a virus... What can I do to make it faster again? Because its been really really sluggish.

If your computer still seems to be slow you may want to try some of the suggestions provided in Slow Computer/Browser? Check here first; it may not be malware. There are reasons for slowness and poor performance besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, too many browser Add-ons/toolbars, failure to clear browser cache, not enough RAM, dirty hardware components, etc. As you use your system it becomes filled with more files/programs and has a natural tendency to slow down and behave oddly so cleaning and regular maintenance is essential. Incompatible browser extensions and add-ons can impact system performance and cause compatibility issues such as application hangs (freezing).
