In general, you will see one or more of the following symptoms:

  • The computer takes longer to boot to the Windows desktop
  • Applications will not load or frequently stops responding
  • System of frequent errors or the errors of loading applications
  • Unknown icons are added to the desktop
  • Usually the system performance slow, especially while browsing Internet
  • Browser windows close unexpectedly or stop responding
  • Change the browser home page and can not be reset
  • Display of more frequent pop-up windows or when the browser is not open
  • No familiar toolbars are added to the browser
  • Default search engine has changed

  • Web pages are automatically added to your list of Favorites
  • Emails or social media messages are sent from the address to users without their knowledge
  • Unexpected and constant proximity to hard drive

There may be other symptoms, but it is a pretty solid list.

What to do if you have a Virus

If you think that your computer has a virus, see the document below for more information on how to diagnose, treat and prevent future infections:

Computers HP - computer is possibly infected with a Virus or malicious software (Windows, 10, 8)

Computers HP - computer is possibly infected with a Virus or malicious software (Windows 7, Vista, XP)

Just a heads-up that, generally speaking, infections of virus or malware not covered under the hardware warranty. You can be referred to a paid service such as SmartFriend or application to perform a recovery.

Some malware or virus can be very persistent and difficult to remove effectively.  Ultimately, the preparation of virus so the best defense.  Delivered to a factory condition can sometimes be faster and easier, assuming you're ready. With this in mind:

  • Don't forget to back up your data regularly, especially data that are most important to you (pictures, videos, personal documents, unfinished).
  • Save if possible in more than one place as an external drive, a CD or DVD.
    * Have own back to the top of all the important data will take some sting out of having to start over *.
  • Make sure that you have created your recovery media and have it available. If you need help with this, consider one of the following documents:

  • I think I have a virus which affects the processing. Nothing seems to fix. All ideas

    No matter what I type with (Word works, even a page like this) the cursor jumps back inserts himself in the middle of a sentence.  It's driving me crazy.  I tried security essentials.  I wasn't expecting it to work.  I just want to know what is the best software to remove the bug of the tis.

    Hello

    It could be the touchpad on a laptop if you have one. Try making sure that you do not have

    Please see:

    http://answers.Microsoft.com/en-us/Windows/Forum/Windows_7-desktop/cursor-jumps-around/3da82209-ee55-4276-b9e7-774e19da8687

    Also, make sure your USB ports. I have a small device at home (jokes), which, when it is plugged in, makes the jump autour mouse and keyboard go crazy. They aren't dangerous, because they have never press on enter or left click, but you may have been pranked courses. Called the phantom Keystroker. If not, ask the nearest person who is more likely to be pranked and ask them if they did. To turn off the unit, simply unplug the device (and if you want to get your own back, plug it into their computer - LOL!).

    Or, you may have malware on your computer. Try some ordinary scanners and free as the scanner online ESET and free malwarebytes. If none of the suggestions work, please reply and we can go from there.

  • I think I have firefox 5 and can not find the orange button on the left, the menus or toolbars so what can do

    I have a computer HP dv6-3225dx laptop running Windows 7 and Avast a/v.I think I have 5 ff but am not sure because I can't find the orange button mentioned in the video on start-up, I can find no navigation or toolbars. I've been a loyal user of ff since you first started the latest version of ff 3.6 and never had a pblm like that. I uninstalled Chrome because of this kind of hassle. I'm just an old non-techie who has not had time to re - learn what seems to be a bunch of esoteric stuff. Can you help pls. Email me I can not find my questions on this help page. TKS a lot.

    Looks like the Navigation bar is what you have now. What happens when you press the Alt key? You see the Menu bar, at least temporarily until you press another button or click a mouse button. When this Menu bar is displayed, press the V button to open the view menu, and then move the slider on the toolbar and click on the menu bar menu item. The Menu bar should then stay open all the time and you won't need to deal with the orange Firefox button.

  • TB don't DL msgs - DL Will one msg, a same, think I have a virus?

    Messages see 'X', but only try to DL, receiving a message - even one - over and over. Do not open it. He said it as "Ivan". The line Re said "Baby". Don't know anyone by that name. Think there might be a virus or something or system is infected if not.

    I have searched the forum and help files, started cold, tried to remove all the add ons have disabled antivirus and firewall. Don't know what else to try. I'm not a power user. I understand things, so I'm not a beginner, so I can follow the instructions to fix the registry, etc., but need specific assistance.

    Appreciate any help. Thank you all. System of TB next report:
