malfunctioning svchost.exe

hello friends !!! i am new to this forum. i need some help. my svchost.exe file malfunctions and the programs stop running at intervals. sometimes a mesage comes up:some data got to be written somewhere but got written somewhere.after which the svchost.exe malfunctions. thx in advance ???

Hello Pulock2009,

1)upload the file svchost.exe to www.virustotal.com and paste the link here.

  1. get mbam, do an update, perform full system scan, remove the infections and reboot if needed.

  2. please, post the log here. (use additional options while posting.)

out of the 2 tasks that u advised me to carry out only one of them was successful:i could only upload the svchost.exe file. when i tried to download the mbam through my mozilla firefox browser the download finished message appeared 2 early.later the exe file when double clickd showed that it was corrupted.interesting to note that this problem has occured earlier also a lot many times.i have not yet checked my e-mail. i wonder how long the report would take to reach?thanks for ur advice!!

I think you forgot to paste the link to virustotal.

get the mbam setup file from other clean pc on to a pen drive and aslo the mbam rules : http://www.malwarebytes.org/mbam/database/mbam-rules.exe

disconnect your pc from the internet so you don’t infect other guys on the net.

install it in your pc. run the updater and scan. if mbam doesn’t start, change the name of the file to xxx.exe and then try.

post back the log.

i couldnot upload properly:it took too much time!!! so i sent it by e-mail. i have not yet recieved the confirmation e-mail.i checked my e-mail account just a few minutes back!!!i have started doing all my activities through a guest account.will that be helpful???personally, i have seen reduction in virus activities like slowing down , hanging, suddenly the antiivirus showing virus alerts etc.(i have avast .i update it regularly).as for the mbam i will try doing something.thx anyways!!

if you use guest account its very safe. as it 97 % of malware can do nothing to your system due to limited access to system files. you will be very much helpful if you use a limited user account like the guest one.

Gateway Operating System Windows XP Pro Edition SP2: SVCHOST.EXE, svchost.exe
( Microsoft )

the md5 is at the top. by the way my guest account login has even failed to stop malware activities.i have again started getting avast alerts out of nowhwere and there were some *.scr files in my network settings
folder in the documents and settings folder. should i upload them to virustotal??upon right-clicking they show options like modify and install.!!thanks for ur advice anyways ::slight_smile:

Running Gateway Operating System Windows XP Pro Edition SP2 leads to infections as WinXP SP3 has been available for over a year so you should go to Tools then Windows Update in Internet Explorer and install all updates as it provides performance enhancements and several Critical updates.

Go to Control panel then Automatic updates then at least enable Notify me but do not download updates.

Get Malwarebytes Anti-Malware (MBAM) then update it then run a Quick scan and let it remove all it finds:

Post its log here after it completes.

Run Secunia Online Software Inspector to see what applications are vulnerable:
