Avast anti-virus cannot start

OK, here's the thing had put end to my 30 day trial of Nod32 Antivirus ESET then I uninstalled and then find a new anti virus I download this anti virus AVAST and installed correctly, but it does not start. The AVAST main menu works, but my laptop is not protected, so there isn't this HOTFIX NOW on top, I clicked it but he needs my permission to run so I clicked the button continue after I clicked on continue the same window came out so I clicked again then the same thing happens so I clicked again the last pop up was then AVAST saying theres something on the Firewall. And so I am irritated and wanted to delete AVAST antivirus but I couldn't find it in Add/Remove programs so I tried to find its location and manually delete its folder, but when I tried to delete the folder it says Destination folder access denied: you need to confirm this operation so I clicked on continue, then the file operation clicked on continue , but the window of folder of Destination refused but this time, the only choice is to Try again or cancel so I clicked the try again button but the same window just keeps jumping up to his irritating so I can't insert my USB on this laptop because it is not protected T_T pls help

Hello

Run the ESET removal tool to make sure it is completely removed as leftovers can cause strange problems.
After you run the tool and did a reboot and re - install Avast.

===============================================================

Here's what I use and recommend: (these are all free and very effective versions.)

Avast and Prevx proved extremely reliable and compatible with all I have
launched on them. Microsoft Security Essentials and Prevx have also proven to be very
reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

Avast Home free - stop any shields is not necessary except leaving Standard, Web, and
Operation of the network.

Prevx - Home - free

Windows Firewall

Windows Defender (is not necessary if you use MSE)

Protected IE - mode

IE 8 - SmartScreen filter WE (IE 7 phishing filter)

I also IE always start with asset if filter InPrivate IE 8.
(It may temporarily turn off with the little icon to the left of the + bottom
right of IE)

Two versions of Avast are available 5.x and 4.8 x

Avast - home - free - 5.x stop shields you do not use (except files, Web, network, &)
Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
disabled - click OK
http://www.avast.com/free-antivirus-download

Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
Finish those you don't use).
http://www.avast.com/free-antivirus-download#TAB4

Or use Microsoft Security Essentials - free
http://www.Microsoft.com/Security_Essentials/

Prevx works well alongside MSE or Avast

Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
or use Google to see how to remove.

http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
(not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
never find anything of note that I started to use this configuration.

  • My 8 victory... infected with the virus cannot start in safe mode...

    recently, my computer of windows 8 has a virus... (miss click an ad pop up and it's on the computer)

    I already got Malewarebytes Anti Maleware and installed AVG, but this virus that bypassed and infected my computer. I tried the standard F8 during startup to go into safe mode and run my anti virus scanners, but apparently it does not work in windows 8. Some say SHIFT F8, that does not work either. Also any other method of setting up safe menu starting boot or mode does not work as it should connect on the desktop to go threw the settings and activate it for the next boot upward. This does not work for me since the virus I have apprently made my fall display driver, after I get my user password to start the desktop computer, so I don't see anything but the pointer of the mouse, everything is black. Y at - it another way to start in safe mode or trigger a recovery system or restore without actually being on the desktop?

    Why windows might change?

    I already ordered a recovery disk as that seemed to be my only option. But the works of windows 8 way I will NEVER buy a computer with it again. Cannot start in safe mode and can't do the simplest task without being a great test. It's crazy. I thought that windows 8 was supposed to be simple and easy to use!

  • Action Center does not detect Avast Anti-virus after system restore

    I had to do a system restore to a point a few days earlier due to some bad drivers.  After you get things restored, I found that the Action Center are most recognized Avast (free version) as my anti-virus software.  It is fully updated and running and work very well.  I tried several suggestions available online, including suggestions on the avast website to check the consistency of the standard WMI (https://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=580&nav=0, 1.20). I also checked that there isn't an underlying virus and tried to 'fix' the installation of Avast in the menu programs and features, as well as a few reboots.  Nothing has worked. This PC is only about two weeks, and everything worked well until the bad drivers and system restore.

    I came here as a last resort...  Any help is appreciated.

    Don't know if this will work for you, but last night I ran a scan with Avast and this morning that action Center of the window said Avast was running but according to Avast started it was running.  Then I disabled the Avast shields then turned on their return and Action Center were more like Avast is not running

  • Impossible to remove or uninstall anti-virus administrator software

    I tried to remove this virus protection software, but I keep getting these messages who turns essentially the same: "Confirmation of necessary administrator" or "access denied user administrator account needs. Despite everything, I am the registered owner, the user only and open a session as an administrator. but, apparently, cannot remove this software at will.  This issue is seriously interrupt my work schedule by blocking programs opens once the downloads have reached the end. I know that these programs are safe and harmless but this "free antivirus software" is controlling my computer and now it seems that I am stuck. I want this program off my computer now, so any help will be most appreciated!

    Thanks for your response and I apologize for not naming software, but I thought that we were warned not not provide company names, etc.  This program is of Avast, referred to as Avast anti-virus program. Let me clarify that I have not installed this software. It was installed by an outfit without my authorization, which announced themselves as a computer repair shop. I took my laptop to this company for an estimate of cost to repair a hardware problem with the speakers. As you can imagine it's a story for another day.

    Respectfully,.

    Avast provide a removal tool to remove the program if you have problems using other uninstall methods:

  • Cannot start place 8 Pro

    I have updated Avast Anti Virus on my place of 8 and there was a problem, so I need to do a clean uninstall and reinstall. Avast has a utility for this purpose. It should run in safe mode. During his run, he asks if you want to start in safe mode and I replied in the affirmative. Once in safe mode I can not select anything utility clean because it appears that the touchscreen does not work in safe mode. If you try to restart it immediately goes to the cleanup utility.

    Any suggestions how I can choose the options in the cleanup in safe mode utility or an option to get out of this loop.

    Any help would be greatly appreciated.

    Thank you

    Hi Lenny,

    As Jeff mentioned rightly Leites, coming 8 Pro tablet comes with a single micro-USB 2.0 port, which is a load and connect the port of combined device.  MIC USB OTG (On The Go) cable is required to connect all USB devices to the Tablet, including the mouse, keyboard or storage for data transfer device.  Here is a link to an example of the OTG cable: http://dell.to/1lCvTGS

    Please use an external mouse to select options in safe mode. I hope this helps.  Let me know if you need more information.

  • Free anti-virus is this useful?

    Is a free anti-virus with a value of use on any PC?
    Because I know spyware and viruses of days now are developing every day, steal or damage to our PC.
    I want to know what is the best to use.

    Should I get a licensed software that is reliable like Norton, McAfee, PC Tools, Live One Care etc. or get a free anti-virus, because a lot of people say it's better that it detects a wide range of viruses, spyware and can repair our PC etc., better than Norton, McAfee, PC Tools and Live One Care.

    In these days of multiple and different types of infections (virus, Trojan, Malware, spyware, etc., you need more of a bloated anti-virus Security Suite to protect you.

    The big 3, Norton, McAfee and Trend are trying to be everything to everyone and fail miserably.

    You are much better running of more specialized programs, particularly for the Malware/Spyware removal.

    I recommend a combination of the following 4 programs:

    http://www.avast.com/eng/download-avast-home.html

    Avast anti-virus is XP and Vista (32-bit and 64-bit Versions) FREE, - automatic update and a user of low resources from your computer.

    And, don't have 1 (one) anti-virus installed / running on your computer at any time.

    Conflicts can occur if you have more than 1 (one).

  • can I use Firefox with other anti virus programs such as avast?

    I have heard do not use more than one anti virus.
    I just buy avast and want to know if I can keep FF on computer?

    The good news is, Firefox is a web browser, not an antivirus program, then Yes, you can use Firefox and Avast.

    You were using before another antivirus program installed a toolbar in Firefox? You can remove those as part of your switch. You can see and disable or remove toolbars on this page:

    Firefox orange (or the Tools menu) button > addons > Extensions category

  • Satellite A300 - cannot logon Windows after you run anti-virus software

    Hello

    I need URGENT help with my A300.
    I have AVG as my anti virus. I ran some scans earlier, and showed a number of threats that heals the VA and clean infections.

    Then, I thought to run it again just to make sure - then 2nd scan. I left do this while I went about my normal activities.
    Some time later, I went back to it. He had put into hibernation. I went from the power button and then loaded up as usual.

    FYI, I have a user account that gives full administrator rights must be able to access as usual.
    After clicking on it, it starts to load for subject a second and then straight away, says saving settings, end the session.

    It continues to be. I tried to log on in safe MODE. The same thing happens. It will not go beyond this point.

    Help, please!

    Memory/University thesis, I have my sister here! I don't know when it was backed up last! :(

    Thank you

    Hi cheekymonkey1882,
    seems that your system is infected with a root kit...

    get a linux live cd or a victory on cd and save important files!
    You must not start from the cd, so no code hard drive will be loaded!

    After saving the files (make sure that you can read!, usb device or other)
    restore the system to factory settings...

    You can try to disinfect the hard drive with the live cd too...
    but remember: If a file is infected it will remove the scanner.

    Good luck!

  • Satellite A300 does not start after the installation of the anti-virus

    Hello

    I brought a Satellite A300 today and loaded it up and it was fine.
    I uninstalled the google toolbar, office and land it came preinstalled with also the mcafree anti virus.
    So I could install my own anti virus.

    After that the system asked me to restart my pc I did.
    Since then, the system cross the 'Please wait' screen
    But it won't let me boot into safe mode. I tried a system restore.

    Any ideas?

    Hello

    To me, it seems that you 3rd party antivirus software caused this strange and confusing problem the Vista OS installed.

    In my eyes a simply, new installation of operating system using the Toshiba Recovery disk would solve this problem.

    If you are able to start the operating system in safe mode and then try to remove your installed Antivirus software, then clean the registry and operating system using the free tool called CCLeaner and try to start the laptop again.
