infection

There are no files. Just the message that protection is turned off. Everything I try to turn it back on fails. All  the scans say zero malicious activity.

But there is something that's causing a severe slowdown and "seizures" I don't know how else to describe it. suddenly screens start stacking up. Hundreds of them one on top of the other out of control , so fast it's unreal, sometimes the computer just goes black then restarts with the message that it hadn't had a proper shutdown. But sometimes there is no way to stop it except to pull the battery. There is nothing in the event log,  nothing on Webroot scans  and nothing on Malware scans.  I took it in for service, but it wouldn't fail while they had it and there was no evidence of these catastrophic events.

Can anybody tell me how to stop these things from happening? I have a 3 year old Dell computer, run windows 7, intel , Webroot antivirus and Malwarebytes  premium. Help!

Hello catcat25 and welcome to Malwarebytes, Continue with the following: Download Farbar Recovery Scan Tool and save it to your desktop. Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version. If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way... Be aware FRST must be run from an account with Administrator status...   Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.) Make sure Addition.txt is checkmarked under "Optional scans"   Press Scan button to run the tool.... It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply. The tool will also make a log named (Addition.txt) Please attach that log to your reply. Let me see those logs in your reply... Thank you, Kevin....

Dear Kevin, I tried to reply last night, to another respondent who offered the same advice but it would not allow me to post. I ran the threat scan which as usual came up with zero threats. My antivirus would not allow me to access farbar due to a signature that didn't meet their approval. Then I read the blog, and it seems that that recommended "fix" is fraught with problems. Inasmuch as I'm not even certain who is offering this advice, I'm reluctant to introduce a questionable download into my computer and further exacerbate the problem.  Thank you for responding, but, for now I will probably hold still and hope this ghost just disappears. Best regards, Cathy

Hello Cathy,

FRST is 100% trustworthy, it is used many times every day not only at this forum but several other forums. Regarding the initial scan, no changes are made and nothing is removed from your system, the two produced logs give an overview of your system and nothing more...

If you do not want to run FRST by allowing your AV to accept it, or even turning your AV off then we cannot progress any further...

Regards,

Kevin..
