![]() It wound up installed on more than 700,000 computers. Researchers now believe that the hackers behind it were bent not only on mass infections, but on targeted espionage that tried to gain access to the networks of at least 18 tech firms.Įarlier this week, security firms Morphisec and Cisco revealed that CCleaner, a piece of security software distributed by Czech company Avast, had been hijacked by hackers and loaded with a backdoor that evaded the company's security checks. But now it's becoming clear exactly how bad the results of the recent CCleaner malware outbreak may be. Hundreds of thousands of computers getting penetrated by a corrupted version of an ultra-common piece of security software was never going to end well. Other readers, note that this fix works only for Surface computers introduced before 2014 later models didn’t use Windows RT.Į-mail tech questions to Include name, city and telephone number.Update: On September 25, Avast confirmed that of the 18 companies targeted, a total of 40 computers were successfully infected with a secondary malware installation at the following companies: Samsung, Sony, Asus, Intel, VMWare, O2, Singtel, Gauselmann, Dyn, Chunghwa and Fujitsu. What can I do?Ī: Your tablet computer needs a manual update so that it can automatically update itself in the future (see /ychyn2uz). Q: My Microsoft Surface tablet computer using Windows RT 8.1 won’t download any updates. ![]() He believes that any PC that ran an early version of the operating system should be upgradeable to the latest one if the owner uses the “Windows 10 Update Assistant” (download it at /mommev8) instead of the built-in Windows Update. It appeared that his HP PC could no longer be updated to newer versions of Windows 10, and the version he had was no longer receiving security updates from Microsoft (see /yc7m5ekn).īut William Miller of Hamilton, New Zealand, said Larriviere’s PC should be upgradeable, even though it’s not listed among the HP PCs that can run newer versions of Windows 10. More on the Windows 10 upgrade issue: Last month I suggested that Francis Larriviere of Opelousas, La., buy a new PC. If that doesn’t solve the problem, your PC may suffer from a software flaw, a conflict between two programs or the accidental deletion of a Windows file (see /y7s7hxxc). ![]() It’s also a good idea to run the free versions of PC cleanup programs such as CCleaner (/okyvdo7) or AdwCleaner ( /huoodp2). To clean these files from the PC, run the free version of the Malwarebytes security program (see /jsdacdk). (To run System Restore, see the Windows 7 section at /kxanto5).īut that might not be enough to prevent infections from reoccurring, because the malware installation files you inadvertently downloaded may still be present on the PC’s hard disk. To rid your PC of malware, try running System Restore to return your PC settings to an earlier date, called a “restore point.” If you choose a restore point before the infection occurred, it will effectively eliminate any malware installed on your PC since that time. Why haven’t you been able to detect malware on the PC? A virus sometime conceals itself as a normal regsvr32.exe file your security software may simply have missed it (no antivirus program catches everything.) But it’s often misused to install malware.Įxcessive “regsvr32.exe” activity that doesn’t trigger an error message suggests that your PC is infected. What’s wrong?Ī: The “regsvr32.exe” file is a legitimate part of Windows that gives programs access to the PC. I have antivirus software, but it hasn’t detected anything. If I cancel these processes, or restart the PC, all is well for a while, then the processes start running again. They keep using more and more of the processor chip’s capacity until the speed of the PC slows to a crawl. Q: After my Windows 7 PC has been running for a while, the Windows Task Manager shows as many as 17 “regsvr32.exe” processes running at once.
