Not only does this allow for the malware to launch at Windows startup, but it can then be run under a local system account with elevated privileges. Keep in mind that this behavior is common for many software installers and, if monitored for changes, can be a source of false positive hits. That said, it remains a great spot for malicious software to dig its heels into your endpoints. Any unknown software should be scrutinized if it is making changes to this part of the registry. So now that you know what these types of Windows Registry attacks look like, what can you do to defend against them?
Consider practical steps to build your defenses. One of the best defense mechanisms against Windows Registry attacks is whitelisting software or maintaining local group policy restrictions.

Last, but not least, a persistence mechanism is put in place: This leads us to our next tactic… Tactic 2: Using run keys and the Windows startup folder to establish persistence Once an actor or piece of malware is on an endpoint, it will usually make sure it can continue to utilize the resources through persistence mechanisms.
Tactic 3: Exploiting weaknesses in Service Registry permissions to establish persistence Another means of establishing persistence while also allowing for privilege escalation is by way of modifying the parameters of services that start each time Windows is launched.

It translates into an excess of supply over demand! Another cause of freezes can be failing hardware, most commonly the hard drive, related cabling or defective RAM.
These defects are often easy to detect but not always so. You should also ensure that you have the latest BIOS and motherboard drivers. They can be out of date on a brand new computer if the person selling you the computer has not updated immediately before handing you the computer.
If the freeze always involves the same programme then you should uninstall and reinstall the programme and check that you have the latest updates. You can also use Google to find out whether others have or have had the same problem. Focus your searches using key words, extracts from Event Viewer descriptions perhaps, and limit results to those within 12 months. Many programmes have dedicated forums where other users may be able to help. A freeze is often be the result of a malware infestation.
In this situation you should not rely on your existing installed software. You need to carry out scans with software like Malwarebytes and Superantispyware. Perversely freezes can be caused by security software. Poor or no maintenance will result in poor system performance. You need to have a maintenance routine. This may include compacting some mail programmes , and should include cleaning with Disk CleanUp or cCleaner and defragmenting.
You do not defragment solid state drives. The most common reason for freezes where the whole system locks up and then seems to play "catch-up" is down to disk issues. Try looking for a S. Thanks for your feedback. All day I've been trying to figure this out, but I've finally come to ask the community. A few days ago I'd get a problem with Windows 7 Home Premium with which it seemed like the Escape key was stuck down. I tried removing the keyboard, trying a new one, and did so twice once before rebooting and once after.
Both times the problem persisted, but only about 30 minutes after the reboot. This went on for a few days until it became an actual problem, coming up right as I was at the user login screen for Windows.
I couldn't keep the password field up long enough to enter it before the Escape key appeared to have been pressed. Logging into a "Guest" type user just less permissions, and time restrictions I noticed I could not even open any windows, as they would immediately be either minimized or a respective "Help" window would pop up.
