regsvr.exe rosource drainer

R

dear friends,
off lately my cpu usage is showing 100% always when I havn't installed any big software and antivirus.
when I go to task manager>processes i find two regsvr.exe image name eating away around 100% of the cpu usage. As a result of this my lappy works very slow, even if it has a 2gb RAM.
pls help to get rid of the problem

That might be a virus. In most cases it is a trojan masquerading as the regsvr32.exe. On the other hand, sometimes, it may be launched by an innocent program running in the background. I recommend that you post a hijackthis log.

Analyse your Hijack this log file here: *www.hijackthis.de/ You can see there are some unknown/nasty processes running on your system

Have a Full Scan with Updated Definition using: *www.superantispyware.com/download.html

Do report back

Those two 'regsvr.exe's are not listed in the Running Processes list. Nevertheless, they might have been executed by MSN messenger or Zoom Player.

However, what caught my attention were these two lines:-

C:\WINDOWS\system32\28463\svchost.exe
and
O4 - HKLM\..\Run: [svchost Agent] C:\WINDOWS\system32\28463\svchost.exe

'svchost.exe' is a Windows process which exists in the System32 folder, not the System32\28463\ folder. You'd better fix this in HijackThis. Try to delete this file manually (NOT the System32 one! Delete the System32\28463\svchost.exe file). After that, run a virus scan.

About your regsvr.exe problem, search for regsvr.exe on your PC. Delete all instances which are not present in the C:\Windows\System32 folder. Also, scan the one present in C:Windows\System32 folder with a good antivirus.

If all is clean, try to exit MSN messenger and Zoom Player and then check the task manager for any remaining 'regsvr.exe' precesses.

One more thing, this seems weird:-

F2 - REG:system.ini: UserInit=C:\WINDOWS\system32\userinit.exe,C:\WINDO WS\system32\wscript.exe C:\WINDOWS\system32\VirusRemoval.vbs

Check your startup list. I reckon you might find a few surprises. Oh, and upgrade to SP3! It's more secure.

Yes, it's malware!! You should ckeck the drives with Malwarebytes Antimalware and Trojan Remover! Also delete the autorun.inf files in the partitions if there is any!!

the two regsvr.exe is not showing in hijackthis tool becoz I hav deleted the two images by ending the processes. Now when I am doing a search for regsvr.exe no search search result found shows. But on restart it again comes..

M

Have you scanned your computer????

R

pls suggest which antivirus to use for scanning

*www.superantispyware.com/download.html

Update it to latest definition and than go for full scan. Do report back after scan

@ritish

The geniune file is "Regsvr32.exe"

If you are not getting startup errors like "Windows cannot find regsvr.exe" or errors in startup of any other programs, its fine.

"Trojan Remover" was a good suggestion. Hard to get past its boot-time scan. If you still got problem after scan suggest you give it a try.

If nothing works, try to block it with the help of a firewall!!
