My system was slow to startup & shut down, downloads were sluggish and at start of each session got the virtual memory is too low message.
Suspecting malware I followed suggestions in the guide:
Downloaded SysRestorePoint, but it would not run.
Ran ERUNT successfully
Uninstalled spybot, installed and scanned with Malwarebytes which found 23 infections.
Downloaded SP3, which took two hours to install.
Start up is better, but still getting the memory message. I ran RegCure, which found numerous errors but would only repair two.
C:\WINDOWS\ has many 4.4 GB & 24,000 files in 1763 folders, most of them $NTUNINSTALL. Is this normal?
Just wanted to make sure I'm on the right track before I proceed any further.
