Hi, if I can just stick my nose in here, being an SSD drive and a year old I am wondering about the condition it is in.
First question is has it ever been defragmented?
As we are in the Vista/Windows 7 threads was the automatic defragmenter turned off when the SSD was new? It should have been by the way.
Although SSD's can be defragmented it is not recommended and should not normally require it to be done, as it seriously overworks the read/write cycles and can hasten the end of the drive.
SSD drives read/write cycle times is finite and though supposedly guaranteed for many thousands of cycles, defragmenting them can rapidly use up those cycles.
Not too sure how it can be determined if this is a problem, though possibly the first thing to look at is what physical size is reported in disk management against the size it should be, or was when new. If certain sectors have died due to over read/write cycling, hopefully it will show up as a smaller drive than it should be.
If the drive doesn't show any problems, and you have the background thought of malware or virus, I suggest posting in the malware section and let the guys look into it for you.
