Microsoft Security Essentials filling my C: Drive

I installed new windows 7, make C: drive 40 GB, install some softwares and Microsoft Security Essentials. but the system had some viruses due to early internet usage. so i scan the system. but after scanning Microsoft Security Essentials keeps on cleaning viruses from 2 days and it is continuously filling my C: Drive. now the space is 1 GB left. how can i free up the disk space. i already cleared all temporary files etc checked program files space etc... i dnt knw how to free this space. i am pretty sure that it is caused by Microsoft Security Essentials.

Run Windows Defender Offline tool , then download and run Malwarebytes. You can free up some space by running Disk Cleanup. But, I doubt that microsoft security essentials is filling your drive. It is most likely the virus you have that is doing it.

your problem is not MSE!

Please follow the excellent advice you received in post #2 by Essenbe.

Here is how to run WDO.

HOW TO USE WINDOWS DEFENDER OFFLINE ON A USB STICK
Windows Defender Offline
is a free standalone, bootable malware and virus remover from Microsoft.
performs an offline scan of an infected PC to remove viruses, rootkits and other advanced malware.

Download Windows Defender Offline (about 764 kB)

You will have the choice of downloading the 32bit version (x86) or the 64 bit version (x64).
The link will help you determine whether you are running a 32 bit version or 64 bit version of Windows

NOTE!! You can download and prepare a 32 bit version using a 64 bit version of Windows
NOTE!! You can download and prepare a 64 bit version using a 32bit version of Windows.

You run the 32 bit version on a 32 bit version of Windows.
You run the 64 bit version on a 64 bit version of Windows.

The 32 bit download file name is: mssstool32.exe
The 64 bit download file name is: mssstool64.exe

For the curious, this program was originally name Microsoft Standalone System Sweeper.


INSTALLATION:
You will need an Internet Connection.
Insert 512 mB (Microsoft’s 256 mB is no longer accurate) or larger USB stick into a usb port.
Run the downloaded program--mssstool64.exe or mssstool32.exe
NEXT button
Choose the option On a USB flash drive that is not password protected
NEXT button
NEXT button
.
The install program will format the usb stick using the NTFS format.
The install program will download about 210 mB.
The install program will name the USB stick WDO_Media32 or WDO_Media64
The WDO_Media32 usb stick will have used space of 255 mB (268,140,544 bytes)
The WDO_Media64 usb stick will have used space of 282 mB (296,165,376 bytes)
You can expect the number of mB to increase as more malware appears.

UPDATE Windows Defender Offline USB stick:
reinsert the usb stick
run the installation program, mssstool64.exe or mssstool32.exe, again.
the update will download about 66 mB (mssstool32.exe) and 68 mB (mssstool64.exe).

Since the malware database is sometimes updated several times in a day, always update before running.

PERFORM AN OFFLINE SCAN
Bootup your computer from the USB stick
Windows Defender Offline will automatically perform a quick scan.
After the quick scan finishes, Choose Full Scan
Select all of your drives

The initial, full scan can easily take several hours, but
Remember, your computer is being very thoroughly checked for all types of malware.


RESULTS OF THE SCAN
The results will be in 4 log files on your computer's disk in:
\Windows\Microsoft Antimalware\Support
======================================================
======================================================
After that, then you will probably have a workable system.

Assuming the system is usable after WDO has done its job, then following will produce a file containing your log files. Attach the resulting ZIP file to your next post.

mse problems

hey all i to have had several problems with mse. first was MPKSL that kept trying to load legacy drivers for hardware that did not exist. second problem is it said that i always need to run a scan even though i didn't. got tired of trying to fix it so i removed it. i also run vista home premium on a different pc and have no problems with mse. seems to me to be a windows 7 compadibilty problem. perhaps i am wrong. i am testing other free antivirus to see how it runs on Windows 7. i have also had problems with viper antivirus and Windows 7 so it may be a compadibilty problem. weird because redman designs mse and windows 7 from what i have read on other sites. oh well bottom line is that they are free and so if i don't like them or are having some issues with them i can always remove them. just my two cents. thanks for the space. poorguy

PoorGuy,
If your version of Win 7 has not been validated or is hacked, then one will have problems.

MSE is Microsoft Security Essentials and is anti-malware software.

Microsoft designs microsoft software.

Redmond is a Microsoft location.

When you encounter a problem or when you have a question, then please start a fresh thread stating your problem or your question, and we will be qlad to help.

I, and I'm in the company of many outstanding experts, use Microsoft Security Essentials and ONLY Microsoft Security Essentials.

Enjoy your Windows 7 software,
karl

mse problems

hey all, as for my copy of Windows 7 it is a legit retail version and not a hacked or pirate version. i do not know why i have the problems that i have with mse on Windows 7 because i do not have them with my iso version of vista home premium which i run mse on. i like mse however i have had some issues along with other people i know that have had the same issues. i have found a solution to my problems by changing to a different antivirus and it is all good at this point. i know that with all new os and other software some quirks can arise and as time progresses things get fixed. i also have had hardware driver issues also but went back to native drivers and solved those problems. i use alot of old pc components from my parts box. i am talking to you from a 12 year old dell that everyone said would not run Windows 7 and that could have been why i had some minor hardware issues which are all resolved. i have used advise from this site in the past on other issues and have good results for the most on the fixes and advice. very useful knowledge from this site and i am thankful for that. as for now all is good and i am going to leave it be cause it ain't broke. awsome site,people and advise. thanks for the space. poorguy
