While online my computer began beeping over and over again. I believe it is my Comodo Firewall because the beeps are simultaneous to each suspicious attempt that is blocked when I look at the Firewall Summary screen. It keeps blocking the same application and target. This is what it is blocking: Application: C:\Windows\System32\rundll32.exe. and the Target is C:\Windows\System32\imm32.dll. What is this? Is this some type of virus or harmful program? If not, then how do I get the firewall to stop blocking it? Right now it has already blocked it 1,383 times and keeps on going. Any help would be appreciated.
Update: Ok, when I turned off my printer the beeping stopped and the blocking of the suspicious attempts stopped as well. Where do I go from here?
Sometimes, and if it is your situation, antiviruses cannot detect malware, while the malware runs. In such cases, the best way is to create a bootable cd/dvd/pen with antiviruses. You have Kaspersky, BitDefender, Avira, F-Secure. Those are the ones I know about.
although imm32.dll is a filename of a legitimate system DLL it won’t hurt running Microsoft sigverif to confirm it’s authentic.
Sigverif will list all unsigned files and since imm32.dll is not supposed to be unsigned, it should not be listed.
sigverif will also be able to point out legitimate but unsigned files (eg 3rd party drivers/dlls/executables) but any unsigned microsoft executable in system 32 folder should be examined.
The same goes with rundll32.exe (running sigverif will allow to confirm if it is an authentic MS ffile)
In this case it is likely that rundll32.exe. and imm32.dll are legitimate apps and those enties in D+ logs are caused by a too much restrictive policy previously applied to rundll32.exe.
