Annoying Infection

[adkinsjr]

My Dell Inspiron (laptop) is only a few months; 64 bit and running Windows 7. 

 

 Several months ago I discovered this very unusual infection that caused my cursor to have a "mind of its' own," at times it would jerk around spontaneously when scrolling with the sidebar, sometimes the cursor would jump up to the "x" and I would accidentally click out,  when I would be typing  I might have an entire paragraph be highlighted real quick and I'd hit a key and erase everything. At first I didn't suspect it was an infection, but I ran malewarebytes anyway and  to my surprise it detected and removed several items; the problem was fixed for several months. 

 

Now it seems to be back again....I have the jerky cursor and sidebar issue, accidentally closing stuff, it's also refreshing pages spontaneously, and it zooms in and out on pages. It's really annoying, I even caught my cursor moving slightly when I wasn't even toughing anything. However, this time malewarebytes nor MSE detect anything after a quick scan, and I update the data base every time before scanning. I also ran a full scan, malewarebytes did find a few objects, I removed them, but it didn't solve the problem, the annoying behavior is there and no scan (quick or full) will detect anything.

 

Any suggestions? 

 

Thanks

Hi adkinsjr,

 

My only suggestion at this point is that you check out the topic about Available Assistance for Possibly Infected Computers. This topic mentions some options you've got. The free one is explained further here, it explains how to get help via the forum.

 

I hope this helped and if you have any questions, please post&ask.

I should have seen earlier that you are an 'honorary member', so you were probably already familiar with getting assistance for possibly infected computers.

The reason I advised it is simply because the symptoms it showed where (most likely) caused by malware in the past (as removing malware seemed to fix it), so my best guess of the symptoms of your computer is, basicly, malware. That the scans show up empty could be, but those are my non-expert guesses, that you got a newer version not yet detected by MBAM or that it got a trick to hide from anti-malware scanner this time. I'd advise you to rule out this possibility first.
