A few weeks ago, my friend opened her computer and this window popped up with helper.dll and helper.sig files showing up. She downloaded a few different malware/spyware/adware programs and ran them, not at the same time of course, and each time her computer seemed to remove those things and work normally.
Then, as time went by, the pop up kept showing up, then she would do the same, get rid of the files and so on. Today however, the pop up only showed the helper.dll files, without the .sig file. Her computer works normally, she scanned for viruses or any other treats, but nothing comes up from her antivirus program.
I was wondering if any of you know what can possibly be doing this and why does it keep repeating itself, if she removes those files with an antivirus program. It's obvious that something causes those files to get back in her system, or to not even remove them completely.
And now, she just recently told me that when she closes out IE, the file iexplore.exe is still in her task manager. And sometimes, there's two of them. Someone told her it might be a virus in her registry, but do you know why wouldn't a virus come up after scanning the computer? And what's with the .dll and .sig files?
Thank you.
