device manager menu opens an closes constantly

Hello Guy,



Thank you for your advice. Let me tell you the whole story.



I couldn't view and download photos from a SanDisk memory card using a SanDisk ImageMate card reader as I usually do. I opened the device manager and the menu opened and closed continuously, blinking about every second nonstop. I found nothing with Malwarebites, and also found no Rootkits. A 2.5 hr long search by Avast Antivirus turned up some trojan horses that I think are copies of the same viruses . HTML:Iframe - ov (trj) Threat severity High and C:\AppData\Local\Windows\...\wbk XXXX.tmp where XXXX = four different letters or numbers for each copy. The trojans were placed in the chest. But the device manager menu just kept on blinkeng. I consulted Seven Forums and got your advice.



I don't have a restore point from before this began.



I booted to safe mode as you suggested and the problem continued. I started disconnecting devices and when I removed the SanDisk ImageMate memory card from the card reader, the menu starting blinking slower, closing for about a half second every 10 seconds. When I removed the SanDisk ImageMate card reader, the menu stopped blinking and stayed open as it should whether or not I was in safe mode. I tested the card reader and card on a different computer and the photos could be displayed and downloaded normally. The card and card reader evidently are working OK. Also the card displays the photo normally in my camera.

I don't see any other problems except I can't use the card and card reader on my computer. I think I may be able to download the pictures directly from the camera with an USB cable. What do you recommend I do?
