Chrome Gets Urgent Patch for Zero-Day Exploit

Google has issued a third zero-day bug warning for Chrome this year. While the browser will auto-update, it's a reminder not to leave it open indefinitely. In short, a zero-day bug refers to the time developers discovered the problem and were able ... to roll out a fix. Ideally, they'll have a head start and can either get the patch in place before would-be attackers even start working on exploiting it. In this case, however, attackers not only know about the bug but are already taking advantage before developers can roll out a fix. Memory Compromised This particular bug is described as a "type ... (view more)

UltraRAM Would Merge Memory and Storage

A new form of computer memory could cut costs and storage space. "UltraRAM" would combine storage and memory on a single unit. Historically computers have always had to use separate units for memory (which is only needed temporarily) and file ... storage (which needs to be available until intentionally deleted or altered). As a rough analogy, file storage is like a filing cabinet, while memory is more like an in-tray, holding information to hand for quick access during the current task. Today many machines use flash memory for both RAM (the main memory on a PC) and solid state drives (a quicker ... (view more)

Chrome Gets Speed And Memory Boost

Google says Chrome will be faster and use less memory with the latest updates. That may not be enough to bring back users who've switched away though. The browser has received three key updates, the first being to the "omnibox." That's the single ... box at the top of the browser used both for typing website URLs and inserting search terms. When users start typing a term, they will now see suggestions, which update as users type more characters. The theory is that they will be able to click on a term and start the search more quickly than typing the term in full. (Source: t3.com ) The ... (view more)

Windows 10 May Get Key Security Boost

Microsoft is testing a new Windows 10 security measure that could neutralize a malware technique. It's called Kernel Data Protection and will protect part of a computer's memory from tampering. The idea is to protect two key software parts of a ... computer: the operating system kernel and drivers. The kernel is the most central part of a system and acts a little like a central command point, deciding what the computer does at any precise moment. Meanwhile, drivers control the way the operating system communicates and interacts with hardware devices. Within the computer's memory, the kernel is ... (view more)

Chrome to 'Freeze' Unused Tabs, Reduce RAM Usage

Google is introducing more options to deal with the Chrome browser using too much computer memory. It's implementing less severe options for users with multiple tabs open. The way Chrome was originally designed means every open tab uses up computer ... memory (RAM). That can mount up substantially if you are accustomed to having many tabs opened when Chrome is launched, or even with Chrome is idle. In turn this will significantly slow the computer down on older systems that don't have enough RAM to begin with. Since 2015 Chrome has had a feature called "Tab Discarding" that kicks in ... (view more)

Scientists: Internet Usage Affects Brain Waves, Memory

Psychiatry experts say using the Internet could "affect our brain's structure, function and cognitive development." An international group of researchers say that as a result of Internet use, we may be losing our abilities to concentrate on a single ... task. The theory has to do with the way many people access the Internet - particularly with email and social media, which often means getting a string of notifications that oftentimes demand immediate attention. This means people spend less time consistently working on one task uninterrupted, which then creates a "use it or lose it" effect on ... (view more)

Can Malware (Spectre, Meltdown) Spy After Reboot?

In regard to last week's article on the Spectre and Meltdown CPU exploits, which affects 100% of all computers made since 1995, user 'rep' had the following question to ask: " Dear Dennis, [Being that this is a hardware exploit], am I right in ... thinking that any passwords, etc, which are stored in the CPU's memory are lost when the computer is shut down? If so, could I simply shut off the computer and reload it every time I want to use Internet banking and would that keep me safe from these exploits? " My response: I posted my original response in the comments section of Friday's article, but ... (view more)

Windows Bugs Could Be Much More Serious

A key security feature in Windows doesn't work as planned. It's not a vulnerability in itself, but means that hackers who find bugs in software are much more likely to be able to do damage. The problem is with Address Space Layout Randomization ... (ASLR). It deals with the way a computer organizes different programs in memory. As an analogy, it's like organizing vehicles of different sizes and makes in a parking lot. Most operating systems support ASLR, which means that when a program starts up and needs to use the computer's memory, it's assigned a random location. In the analogy, think of cars ... (view more)

How to Fix: Uninstall, Reinstall ScreenConnect Server (Mono Out of Memory Error)

Infopackets Reader Steve V. writes: " Dear Dennis, I came across your post on screenconnect.com, entitled ' Mono eating too much memory (Linux) ' and am having the same issue. It seems that ScreenConnect is uncontrollably eating memory - for ... example, when I click on client previews, the mono process eats 300mb+ of RAM and will continue to do so for each click. Surely this is not right! At this point I receive 'Internal error' on my ScreenConnect browser control panel (where I can view my clients). Ultimately, /var/log/messages reports 'Out of memory: Kill process xxxx (mono) score xxx or ... (view more)

How to Fix: Make Firefox Faster; Enable Multi-Processor Support

Infopackets Reader Jesse T. writes: " Dear Dennis, A friend of mine told me that the new version of Firefox is a lot faster, but requires special configuration changes in order to get the speed boost. Do you know what she is referring to? How can I ... make my Firefox faster? " My response: Your friend is correct - the latest edition of Mozilla Firefox (version 48) includes a major overhaul to allow for multi-processor support, though it may not be enabled by default on some systems. That is because some systems may use older add-ons that may interfere with the multi-processor support feature, ... (view more)
