Last Saturday, my computer started acting funny. The mouse lagged. The internet was freezing. The entire computer was sloooooow.

 

Then, I got a Blue Screen, but it came and went too quick for me to read and write what the error was. When the computer came back on, it was doing a CHKDSK. 

 

I didn't use my computer until Sunday afternoon, and when I did, it was still running rather slowly, so I decided to run my MalwareBytes and AVG Antivirus. Both indicates pretty quickly that there were infections on the computer. But, they would freeze up a quarter way through the scan and not finish. For MalwareBytes for example, it took 2 hours to scan 3,000 files. Clearly, there are far more files on my computer than 3,000 and who knows how long it would have taken. 

 

I cannot install Windows Updates. I have downloaded and executed a number of different programs, all of which freeze in the middle of the process. I downloaded HiJackThis and it can't create a log. I have tried sfc/scannow and it gives me an error message as well. I have tried all these things in Safe Mode, and even in safe mode, it will not execute.

 

I did look at the Event Viewer back to around the time it started acting funny, and around that particular time, there were a lot of errors with the name iaStor, which according to Google seems to be a virus. The problem is, without an ability to scan, I am unsure how to get the computer cleaned up.

 

Once the computer gets working, it is fine. Symptoms: Upon booting up the computer, it takes a long time to boot up. Everything seems to be Not Responding at first. Eventually, I am able to bring up the task manager and close all the programs that are eating up memory. Most of the time, about 5 minutes after booting up, a little box pops up about Windows Explorer not responding, and I click to close and nothing happens. Another weird thing is....several minutes after the computer is turned on, the Windows sound goes, the one that plays when a computer is first booted up. Once that sound plays, all the other programs seem to come to life, and from there, I am able to at least use the internet.

 

Suggestions?
