I've just recently downloaded the latest version and definitions for SAS and I'm now having scanning problems. I should note the the problem I'll describe occurs in both the "Quick" and "Full" scan modes. This problem began with version 2.27 and continues in 4.29.
After initiating a scan, the scan of the "Memory" and "Registry" go fine. I can then see files being scanned, however, there is NO count being shown under "Files" for nearly 20-25 seconds. Then the counter starts to register, but it only reaches 5, then the PC freezes-up. It's appears that SAS has scanned hundreds of files before the counter even moves from "0" based on the activity being shown near the top of the window.
I've uninstalled and reinstalled the program using your SAS Uninstall Assistant, but nothing changes. I even went into MS Install Cleanup and noticed that it was still showing a prior version the latest SAS I updated, and I removed it. I also noticed that after a couple of reboots following the "freeze-up", I'd open SAS and it would ask if I wanted to see what was updated (I had previously declined on this window earlier). It now stops doing that, and recognizes that definitions are current. The program version I'm running is 4.29.1002, and the definition database version is Core 4110 and Trace 2050.
I've no reason to suspect any type of infection. I've run SAS on a weekly basis for quite some time and have no problems. I also tried Malwarebytes (during that time that SAS was taking so long to load and update). By the way, improvements in this regard are significant. I'm not showing any current problems based on doing a full scan using Malwarebytes today.
Please advise, and thank you for your help. -SA Jack
