Windows 10: Need help restoring PC - possible virus attack and/or serious corrupted data in ssd

Hi guys, Here's what happened as in a timeline so you get an idea. I could still feel that my laptop is not running well. Background:My laptop specs are 16gbram, 3050, ssdI have bitdefenderAll win11 updates are installedTimeline:1. My laptop Asus ROG Zephyrus 14 crashed all of a sudden and booted to BIOS. I try save and quit but it keeps booting to BIOS. That's when I noticed, BIOS is not detecting SSD Storage: No storage device present. I turned off and turned on again. It went to disk repair screen Fixing :C Stage 2 etcetc.2. Laptop booted after that. But as if its a clean install. Locks

Possible Virus attack

Recently I scanned my Windows PC using Avast and it showed the presence of some weird malware in the result. It couldn't remove all of them nor it could move all the malware to the chest.

Now I am facing some serious trouble:

1. My start menu is not working nor Cortana (search) is opening.
   
2. Task bar icons are not showing up. I am able to click the task bar icons but I can't see the icons.
   
3. My internet connection (modem) is getting disconnected by itself.
   
4. When I click on the personalize settings, it says "This file has no program associated with it."
   
5. There are some serious troubles.
   

Please help me. Will restoring to a previous point remove the malware?

 

Attacks Discovered that can Corrupt MLC-based SSD Data

It appears that although MLC NAND-based SSDs have many advantages to HDD's from a physical-reliability point of view, the old spinning rust drives might still have one advantage over SSDs: A specially crafted write operation can't corrupt your data.

That's what a new report from Carnegie Mellon University, Seagate, and ETH Zürich is showing: That MLC-based SSD Drives are vulnerable to data-corrupting attacks as simple as a specially crafted write operation.






The first attack is compared to a "row hammer" attack, in which thrashing the drive with read or write operations along the border of a cell can corrupt legitimate data in nearby cells. Most attacks operate in variations of this principle, but some also rely on techniques such as special sequences of operations that will cause cached data and pages to be lost, effectively ruining your precious file the SSD was waiting to write to its media.

HDDs for their part, are not completely data safe even when they are operating correctly. They have a UBER (unrecoverable bit error rate) rating that indicates how often the HDD will make a (mostly random) mistake reading its data from the platter. This phenomenon (often referred to as "bit-rot") is not common in a correctly functioning HDD, but it does happen. The difference is it's not directly triggerable by a specially crafted write: Bit-rot errors are more or less random. Needless to say, the potential for malware to utilize this trigger-able corruption on your SSD is not a good thought at all.

If you want the technical details, they are available in the source link. For now, all you need to know is pretty much all SSDs are vulnerable to what was discovered here, but no exploits are live yet and due to there being no money in just wrecking your stuff (as opposed to say, ransoming it), there probably won't be a significant amount of malware featuring this exploit. Just practice good data hygiene as per usual and chances are all will be well. We don't mean to chase you back to HDD land just yet.

Oh, and one final caveat: SLC SSDs are immune, but good luck finding one that isn't outrageously expensive.
