What did system restore do to my virus?

Anonymous

I got a virus from a sketchy website which told me that my files could not be found whenever I tried running a program, even system restore wouldn't load. I knew about the virus only because windows kept popping up every second telling me about it and telling me to buy their anti virus ____ while I already had Norton. I got Norton to work and ran a complete scan to find nothing. So, since I was scared watching the pop up windows appear one by one saying they have lost my files to various things, I panicked and took out my battery and put it back in(I didn't know how else to get into safe mode).  Once in safe mode, I ran the restore to a few days ago when i know i didn't have the virus.  Every thread I read says that system restore cannot remove viruses but doesn't explain why.  My computer is fine now so where did the virus go then?? Will it come back? Norton says everything is fine but then again it didn't find it before either. 

I don't know if tis matters but I have a toshiba laptop(L655) that I got a few months ago.

    Hi,

    Some virus can be removed by using System Restore however the danger is that using it

    will allow many types of malware to infect the Restore Points.


    If you need to check for malware here are my recommendations - these will allow you to do

    a thorough check and removal without ending up with a load of spyware programs running

    resident which can cause as many issues as the malware and maybe harder to detect as the

    cause.

    No one program can be relied upon to detect and remove all malware. Added that often easy

    to detect malware is often accompanied by a much harder to detect and remove payload. So

    its better to be overly thorough now than to pay the high price later. Check with these to an

    extreme overkill point and then run the cleanup only when you are very sure the system is clean.

    These can be done in Safe Mode - repeatedly tap F8 as you boot however you should also run 

    them in regular Windows when you can.

    TDSSKiller.exe. - Download to the Desktop - then go to it and Right Click on it - RUN AS ADMIN

    it will show any infections in the report after running - if it will not run change the name from

    tdsskiller.exe to tdsskiller.com. Whether it finds anything or not does not mean you should not

    check with the other methods below.

    Download malwarebytes and scan with it, run MRT, and add Prevx to be sure it is gone.

    Hi,

    SFC only repairs some Windows files, it does not check for malware and you could have malware

    even thoough and SFC scan shows no issues. Running SFC before malware is clear carries the

    same risk as running System Restore in that it can actually help spread some malware.

    Please use the methods in the reply above to do a thorough check.

    Are you still getting the messages from the scan antivirus that you need protection? If so is there

    any name or site associated with it?

    Windows will notify you that your are not protected (popup in lower right corner). However in your original post "I got a virus from a sketchy website which told me that my files could not be found", if the website originated the warning it fake.

    What version of Norton do you have? N360V3 or 360V4, NIS 2010 or 2011, NAV 2010 or 2011 or other.

    The windows pop ups telling me to get an anti virus software looked like it was part of windows.  It didn't look like any anti virus scams I've seen before(and I've had a lot unfortunately).  It looked really legit.  So will windows ever ask me to get their preferred brand of anti virus software(does it even have one)? and are you sure this was fake?  The sfc scan said everything was fine.

    The web site was trying to fool you into installing their software to remove a non existant virus. The popups may have been the tip of the iceberg and system restore fixed that. As long as you did not download the fake AV software or run their online scan you should be OK.

    Run the SFC  /SCANNOW  command. This will check and repair if necessary any critical Windows system files.

    Click on Start/All programs/Accessories then

    Right click on Command Prompt option and select 'Run as administrator'.

    At the command prompt enter:  SFC  /SCANNOW
