    My email has been hacked and used to send Spam. I have to perform a virus check, or simply change the password?

    Do not install or run an anti virus app.

    How do you know that your email has been "hacked"? It is a common practice for spammers to forge an envoy from the e-mail address. It may be that your email address has been misused. There's nothing to do if this is the case for you. The spammer will soon pass and usurp another email address.

    It's a good idea to immediately change your password by email if someone would actually managed to access your e-mail account.

    Hello

    All files in the TEMP folder can be removed by using disk cleanup you do not here.

    Do not perform any upgrade suggestions while there is no threath of malware on the computer.

    To upgrade to Windows 7, you should check with the manufacturer of system and various device manufacturers to ensure
    There is some BIOS, drivers from the chipset level low and other important drivers for your system. Check their
    forums for known issues with an upgrade.

    Run the Upgrade Advisor, and check with the center of compatibility for your key features.
    Some system manufacturers also have an online help and information for the upgrade to Windows 7.

    Does anyone know why windows 7 doesn't recognize iolo labs, System Mechanic pro as a valid virus / anti-malware program. It works fine in the background and continue to check for all types of viruses and software spies /malware.

    Hello

    You probably have an anti-virus/anti-spyware product testing iolo System Shield. It is a different program.

    There are many antivirus programs that do not properly report to the center of the Action.

    If you're absolutely sure that you have an installed antivirus program and it works correctly, you can turn the center of Action by checking for this component.

    Open Control Panel/Action Center.

    On the left side of the window, select Change Action Center settings.

    Remove the check box of the element of protection against viruses.

    You can search through the event viewer to see the items you deleted.  If you're just going through your add/remove program list and want to know if you need the program, then I watch the last time that it has been used and then get on the internet if you do not know what the program does.  The link below gives some good tips to keep your system works well.

  • During the installation of XP bluescreen error 'Check for viruses on your computer' and 0x0000007B error code

    All of a sudden my computer will not start and I tried to reinstall/repair the operating system.

    When you try to install the OS, when booting from the CD and before asking questions of formatting, it displays a blue screen. sayng 'Search for viruses on your computer' and finally 0x0000007B, etc...

    Thanks in advance

    If you use hard drives SATA and AHCI is enabled in the BIOS, you will need to press F6 and add SATA drivers when it says press F6.

    Otherwise, you will need to change AHCI Mode IDE in the BIOS (BUT you cannot change it back to AHCI after). Well, you can with a registry hack

    Or you need to integrate the SATA drivers, then reinstall windows

    This is what the stop error 0x0000007B means. He can not find the hard drive (if you add or integrate SATA drivers). It will crash before you get the installation / configuration screen (XP, since the XP CD doesn't have SATA or RAID drivers on that).

    And clear the virus check option in the BIOS if its permit

  • Suspicion of virus

    Suddenly, I got a message on my MacBook that my computer has been infected by a virus and I need to contact a Web site for my MacBook cleaned. According to me, which is a spam that I have been informed by Apple and by people who use Apple years not to bother with virus check my MacBook has been secured. Once this message appeared more or less my machine froze and I had to quit and restart - what would be the best thing to do now? Don't want to make things even worse.

    It's a scam.

    If you force quit Safari, and then restart with the SHIFT key which should get rid of the nuisance.

    Your friends are correct. You do not want any AV installed on your Mac. It will be you didn't offer any additional protection and most like cause problems on your Mac.

  • Help! Computer hangs during attempts to complete or defragmentation (MS) (MSE) virus scan or CHKDSK C: /f

    Help, please!  My computer freezes whenever I try to run a full scan or use the MS defrag it came with.  I have an important job who needs to back up, but I'm afraid that I shouldn't be where it is a virus.  I would really appreciate the help.

    Details:

    Windows XP Home Edition
    Microsoft Windows
    Version 5.1 (... Service Pack 3)

    Current system:
    Microsoft Windows XP
    Home Edition
    Version 2002
    Service Pack 3

    Fujitsu Siemens Computers
    Intel (r) Core (TM) 2 CPU
    T7200 @ 2.00 GB of RAM

    Info of current Disk Defragmenter:
    C: NTFS 112 free capacity space 47 GB space 43%
    (Was only 15% of free space at the beginning of the problems, before I removed or reduced the old files)

    Antivirus:
    Originally from Norton 2006, now uninstalled and replaced with the current Microsoft Security Essentials

    Browser: firefox version 3.5.9 (IE too but do not use)

    The story so far:

    FIRST PROBLEM: ACCIDENTS CAUSING SLEEP/HIBERNATE / SCREENSAVER?
    I am back from vacation and turned on my computer.  Soon, he wanted to upgrade me to the latest Firefox (must have been 3.6?).  He may have also updated my windows automatically.  Then whenever the standby/hibernation/standby screen came (not sure what was the culprit), the computer would crash - I would just get a gray screen when I tried to find by moving the mouse.

    'SOLVED' BY:
    I restored the system to a few points saved from before I agreed to install the new firefox.  I also stopped the computer goes on standby or into hibernation.  I couldn't work on how to disable the screen saver.  Standby/hibernation/standby order screen blocks the computer after that, and I took care not to upgrade to firefox 3.6, once again just in case, stay with the version that I was on, but continued to accept upgrades (now on 3.5.9).  I have always been accepting the automatic updates of windows however, because I was told that I should do.

    UNRESOLVED ISSUE: ANTI-VIRUS AND DEFRAGMENTATION DOWN EACH RUN
    So, I now had a more usable computer.  I tried to check virus, but the virus check (Norton, 2006) would be broken whenever I tried to do a full audit.  I analyzed in the MS Defrag tool that came with my computer and I saw that I had 15% free space, so I tried to Defrag.  Defragmentation has also crushed every time, usually at 3%.

    26 January:
    CRASHED ON THESE FILES:
    -Defrag crashed on A0044502.rbf
    -(J'ai remarqué que le nom était semblable à celle de la vérification de virus s'est écrasée avant)
    -Defrag then crashed over the other in a different file type, but I didn't note it (tmp.edb?)
    -Defrag crashed on C:/System volume information/_RESTO~1/RP320/A0045026.rbf (I think that virus check then crashed on this one too)
    -virus scan crashed on A0045030.rbf

    I ran cmd chkdsk_/f, as told to a friend.  He made 3 times and the screen went too fast to see writes said before he started.

    -defragged once again, it crashed on A0045107.rbf

    CLEANUP TO FREE UP SPACE FOR SPRING:
    I then had the end of emergency work, so did not have to try to solve this problem for weeks.  I just don't have the virus scan and did not try to defragment, therefore had no crashes.  When I had spare time, I went through removing unnecessary programs, deleting unnecessary files of old works and by reducing the great graphics work at smaller sizes.  At the time I had finished my rush job and could return to the problem, I got 43% free space.

    Wednesday, April 8:
    BACK TO ATTEMPTS TO SOLVE THE PROBLEM:
    -J' uninstalled Norton 2006 and then installed Microsoft Security Essentials to see if it would take viruses.  QuickScan revealed no.  Full analysis has crashed every time unfortunately.
    9 April:
    -CHKDSK C: /f or crashed was working incredibly slow (1/2 hour on the same file) both times I tried to do.  Both times it crashed on 66% to check the data of the file (4 of 5)
    SFC - typed term: the black box will Flash up but then disappears so fast, you can hardly see.  Nothing else happens.  I tried several times.
    -J' restarted the computer in "safe mode with command prompt" and tried SFC/scannow and got the following error:
    "Windows file protection could not initialize a scan of protected system files.
    The specific error code is 0x000006ba [the RPC server is unavailable]. »
    -J' rebooted 'safe mode' and typed SFC term.  Same thing happened as has happened before in the windows.
    -J' rebooted 'safe mode' and tried a full analysis of the MSE virus.  After an hour of working, it crashed in this file: C:/System Volume Information/_restore{5C5FC002-5FB5-4560-96DA-E32D8569FB2E}/RP320/A0045038.rbf.  This happened just after I clicked on a tiny with my notes Notepad document, although I don't know if that's what he did or has not already been blocked.  I managed to take a break and he reactivated just before it crashed.  The complete virus check was almost over, guessing 80% to the green bar.
    -J' tried to Defrag in 'safe mode', which soon crushed on C:... A0070595. MSI
    All these accidents April just cause the screen appearing to freeze because the virus check or defrag did not move from the file it says that it was on... then when I would try to stop it, the screen completely freezes so I have to manually shut down.

    Please help me solve this problem!  Should I save my work?  If I back up and there is a virus, then my backup external hard drive could be infected.  But if I do not support, I could lose a lot of work.

    Thank you very much.

    Speedlauncher Adobe is a legitimate program, while orangefirefox.exe presents itself as an infection by the worm on a google search.

    It's a little unusual that Kaspersky would freeze even in SafeMode... perhaps running a chkdsk might help take the files that programs AV and defrag crash on: http://support.microsoft.com/kb/315265

    You may disable the system restore: http://support.microsoft.com/kb/310405 and this should get rid of all the restore points and then hopefully no longer break when scanning, but make sure you turn it!

    But sometimes I come across systems that had infections as well as at the end of all the damage that has been caused, it is better just to do a reinstall.

    --> I hope this helps! Please vote or mark as correct answer if it doesn't :)<>

  • After removing a virus from my computer, I can't access any of my programs like Windows Media Player. Pop - up says choose program to open the file type.

    After removing a virus from my computer last year, I struggle to access most programs such as media player and other things.  When I try to open something, I get a popup asking me to choose the program I want to use to open this file. For some programs, this file is actually listed.  But for the most part, they did not.  For example, Nero express is what I use to copy CDs or DVDs.  I have to go into a safe mode to use it as well as using programs to run virus checks.  I was told that the virus had somehow corrupted or affected my file extensions.  I almost had cheated using powerful PC Max but did some research beforehand.  Any suggestions?

    original title: File Extension problems

    If you need to go to Safe Mode in order to use certain applications (for example, Nero Express), particularly antivirus scans, you most likely have not successfully removed all malware from your computer.

    How did you remove the virus from your computer last year?

    You then install an antivirus application?  Which one?  Are you still using it?  What's his current subscription? Its subscription has already been authorized expiration?

    What version of Windows, including service pack, do you use?

    What other anti-malware software do you currently use?

    Have you analysed recently with the following free tools?  Otherwise, download, install, update and run scans (not simultaneously) with each of them:
    MalwareBytes AntiMalware
    SUPERAntiSpyware
    Like many also restore file associations.

    • Right-click on a file and select open with > choose program.
    • Look in the lists of programs (split in 'Recommend programs' and 'Other programs')
    • If you can't find the application you want to use to open this type of file, click on the button "Browse".
    • The "Program Files" folder should open (if it isn't, go to C:\Program Files
    • Find the program you want to use.  If you are looking in C:\Program Files\------, you determine which file is the actual program.  You should be able to tell from the icon.  If not, see note below)
    • Select the program (the exe file or the name of the program in one of these lists) and check the box "always use the program selected to open this type of file"
    • Click OK
    • Repeat the above for each type of different file according to the needs

    Note: If you need to determine the EXE file for an application, just right-click on the shortcut you use to start the program, and then select Properties.  Click on the tab "shortcut".  The 'Target' box contains the path name to go to the executable (EXE file) for the program.   For example, the executable file for Firefox is "C:\Program Files\Mozilla Firefox\firefox.exe"

    There are a few exceptions, including but not limited to Microsoft applications, which use a more obscure reference to the target.  Word, for example, indicates the 'target' as a 'Microsoft Office' gray of no matter the version.  The real exe for Word is 'C:\Program Files\Microsoft Office\OFFICEnn\WinWord.exe' where the nn refers to the version of Word that you have (Word XP/2002 is 10, Word 2003 is 11, Word 2007 is 12, Word 2010 is 14).

    If you need assistance with a shortcut that does not directly show the name of path, ask.

  • cannot restore from the previous date says computer is unprotected I just get rid of the virus of audit system

    rid of virus check system but cannot restore the computer to the previous date

    You never said how you got rid of the "System Check" malware. As far as we know, he is still there. Follow these instructions (if you have not already done so):

    Also, as Jose pointed out, there are programs that are designed to interfere with the system restore (Norton is one of the most common). But there are really two questions. First of all, we will treat your malware problem. We can always revisit SR at a later date.
    Finally, even once as Jose pointed out, you NEVER run the system restore after the removal of the malware! Which could only bring him back! That you have to turn it off and then put it again, which will REMOVE all previous restore points. You really all gone!
  • Lost access to the programs, not a virus or registry problem. Lost the rights to the user (?) but cannot access restore or modify user accounts

    1st, I tried almost every fix suggested on this relatively common problem with no joy.  It is not a virus, unless it's something very new not found by all the usual scanners.

    Only way to access the programs EXE is to run the command prompt by going to with CTRL - tour of the new task (run) in the Task Manager menu and then navigate to the appropriate directory and run the program from the command prompt.   Run virus checker and run various registry fixes recommended here with no joy.  Safe mode does not help with the launch of the EXE.

    Because I get the 'Windows cannot access the specified device, path or file.  You can not have the appropriate permissions to access the item.  When I try to run an exe from a link, I think I have lost the user privileges.  But, since I can't change the accounts of users or the restore, I can't try to do anything there.

    This problem occurred after uninstalling several old unused programs followed by performing a disk defragmentation.  (everything is done using Microsoft System Tools).  PC worked after doing these things in vain after the next reboot.

    Curiously, I CAN start the web browser from the start menu to post this message.

    Another clue: I can't start programs by clicking on them, but I CAN run the program by opening a file type associated with this program, i.e., opening a file named text.doc will cause Word to open.

    I am a fairly experienced user, but I'm stumped.  Any suggestions?

    Found solution...

    Looked user accounts change program but cannot find or identify it was so impossible to try it.

    I was finally able to identify (in trial & error) the restore program and run it using the command window.

    The program (rstrui.exe) was found in C:\Windows\System32\Restore\rstrui.exe

    I was able to run and to restore to a date when this problem started and that fix.   Still don't know what was the problem of the root but happy to be able to fully use this PC back again.
     
    Thank you to everyone who made suggestions.
