  • Debu says:

    Download Avast Antivirus and update it.Schedule a boot-time scan .It is free and will not slow down your computer.The link is given below.

  • Frank N. Stein says:

    Go into safe mode with networking (turn on the pc and tap f8 until the BIOS screen comes up). Go to download.com and get Malwarebytes, update it and run a full scan, all while still in safe mode.
    That should kill whatever you have.
    And yes, trojans are bad.

    Step 1.
    Download Avast! Home Edition as this is THE best free antivirus protection out there. Only drawback is you have to register within 60 days for free and every year after. But hey! You get it forever!
    Anyways you also have to manual scan, but it isn’t a resourse hog and it scans everything your computer writes and reads as well as internet sites and emails. I love it. As well they update it about every day!

    It found several viruses after I deleted Norton 360 and has found several since.
    Download here: http://www.download.com/Avast-Home-Editi...

    Register here:

    Step 2.
    As well try downloading malwarebytes anti-malware, updating, and scanning.
    MBAM redirects you here for download. (MBAM) Go here to download: http://www.download.com/Malwarebytes-Ant...

    Step 3.
    Proceed by downloading "SuperAntiSpyware Free" from the link below (As the title suggests, this is also free), follow any
    instructions required to install it, update the virus definitions, then run a full scan, also clean any infections found
    after the scan has completed.
    http://www.superantispyware.com/

    Step 4.
    You may also consider to be sure that all Malware has been removed from your system download “Kaspersky’s Virus Removal Tool" (Free) from the link
    below and run a full scan, this will already be updated to the day you download and install it, after the scan clean any
    infections found. download here

    Step 5.
    Consider doing a scan of your computer with MBAM and superantispyware every 2-4 weeks with a maximum of a system scan every month. (I recommend 2-3 weeks.)

    P.S. make sure to unistall all other antivirus products before installing avast and never have more than one installed at a time.
    Hope this helps and enjoy a better computer!

    op. system install / re-install steps

    print a copy of this file

    print a copy of computer notes

    export browser Fav’s / bookmarks

    back-up files, programs ;

    power down

    disconnect network and external drives

    power up

    delete tif files ( temp internet files ) and cookies;

    un-install programs;

    delete folders;

    delete accounts

    empty recycle bin

    restart computer

    Go to BIOS and set boot order with CD boot 1st

    place O.S. CD in CD drive, ‘cept don’t close it

    power down

    close CD drive with O.S. CD in it

    restart computer

    format primary HDD;

    ( Fn + F10 ) = disc eject ( DELL )

    install op. system;

    adjust screen resolution;

    load software for external drives and hardware;

    test for internet connection;

    install additional programs as necessary

    If your computer is several years old, consider buying a new hard drive for the fresh install of the op. sys..

    When re-installing the o.s., allocate 15gb (15000mb) of space for the op. sys.. Format in NTFS. Partition the rest of the hard drive in 7000mb to 20000mb allocations creating up to 10 partitions. Then, after you boot, you can allocate / format the rest of the hard drive under disk management;

    >(r-clik) my computer
    > manage
    > disk management

    Allocate +/- 7 to 20 gb of space for each partition, format in NTFS.

    Install additional software (Adobe pdf reader, Java R.E., printer, wireless adaptor, office suite, web browser, widgets,etc.) to a low capacity partition.
    AVOID installing to the partition that host’s the op.sys.. AVOID storing anything in the user account “My Documents” folder as that will consume space in the host partition.

    Download to a low capacity partition, install software and programs to another low capacity partition. Create and download documents to another partition.

    leave at least one partition unused, for migration. At least once a year, migrate your stuff to a unused partition, especially if you do a lot of editing, then format the abandoned partition, for the next time.

    With only the op. sys. on the hosting partition, it will be easier for your computer to run the op., and easier to run everything else.

    And, with your files and software on other partitions, your stuff is already in back-up, and the next op. Sys. Re-install will be already half done and much easier to do and you will only have to format the host partition and not the whole hard drive

    Also, increase your RAM to at least double of mfg. Configure or even max it.

    Check the RAM and CPU load with the task manager to determine if you need to increase the RAM capacity;

    1st> (r-clik) taskbar
    2> task manager
    3> performance

    Get widgets to monitor the RAM load and CPU load

    To be more thorough “wipe” the hard drive before the op. Sys. Install with DBAN

    Use Eraser to overwrite the contents of the recycle bin instead of emptying the recycle bin;

    1st> Open Eraser
    2> clik explorer tab near bottom left
    3> clik recycle bin the the explorer tree to show contents of recycle bin
    4> edit > select all
    5> drag and hold contents over the eraser tab
    The explorer closes and eraser opens
    6> drag contents back to the eraser que, drop contents
    7> set eraser to make one pass;
    Edit > preferences > erasing > pseudorandom data > OK
    8> (r-clik) eraser que> run all > close

    Occasionally use ccleaner for maintenance purposes;

    Occasionally, create a new user account, copy / paste contents from the current user account, to the new user account, then delete the old user account
