Suspicious network connections

MemTest64 – check your system memory for problems at the hardware-level.


TechPowerUp Memtest64 is a free lightweight, standalone utility that lets you check your system memory for problems at the hardware-level. It has a graphical interface, and can be run from within Windows.

Memory hardware errors can cause major application crashes, blue-screens of death (BSODs), and data corruption. It is caused due to either faulty hardware, or bad memory timings/frequency. Memtest64 lets you test your memory without having to pull out an MS-DOS boot disk. The utility loads your physical memory with test-patterns, and can push other applications into the pagefile to free up memory for testing.
It can also be useful to overclockers who are looking to maximize memory performance by playing with timings and DRAM speeds.

Features
Runs on Windows XP, Vista, Windows 7, Windows 8, Windows 10. 64-bit OS only
Supports all modern processors, including Intel Core and AMD Ryzen
No reboot or DOS-mode required
You can control how much memory to test, to reduce operational impact
Memory is tested using various detection algorithms
Errors will be detected automatically
Does not require Administrator privileges
No installation or registry modifications required.

GSmartControl – Hard disk drive and SSD health inspection tool.


GSmartControl is a graphical user interface for smartctl (from smartmontools package), which is a tool for querying and controlling SMART (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk and solid-state drives. It allows you to inspect the drive’s SMART data to determine its health, as well as run various tests on it.

GSmartControl supports ATA drives (both PATA and SATA), various USB to ATA bridges and drives behind some RAID controllers. See Smartmontools USB Device Support page for an (incomplete) list of supported USB to ATA bridges.
Supported RAID controllers:

Adaptec (Linux, some models only)
Areca (Linux, Windows)
HP CCISS (Linux)
HP hpsa / hpahcisr (Linux)
Intel Matrix Storage (CSMI) (Linux, Windows, FreeBSD)
LSI 3ware (Linux, Windows)
LSI MegaRAID (Windows)
Note: Smartmontools supports even more RAID Controllers. The drives behind such controllers can be manually added to GSmartControl using “Add Device…” functionality or --add-device command-line option.


Features
automatically reports and highlights any anomalies;
allows enabling/disabling SMART;
allows enabling/disabling Automatic Offline Data Collection – a short self-check that the drive will perform automatically every four hours with no impact on performance;
supports configuration of global and per-drive options for smartctl;
performs SMART self-tests;
displays drive identity information, capabilities, attributes, device statistics, etc…;
can read in smartctl output from a saved file, interpreting it as a read-only virtual device;
works on most smartctl-supported operating systems;
has extensive help information.
