My Acer computer 4745G only bought 2G memory, 1G graphics card, i3 quad-core processor 370M, needless to say. It's much better than someone else's book. Anti-nonsense aside, that's the end of it.

First of all, use security antivirus software to scan the computer, and remove the existing virus threat, if there is no security software, then please ** security one, because antivirus software can only achieve the commonly used virus removal, and they may be different for the surface, so it is recommended that you can use the two antivirus software together.

Secondly, if there is a deeper level of virus in the computer or the virus deleted by the antivirus software in the same way, then it is recommended that the user format the entire hard disk and repartition, format the hard disk and repartition can refer to the "U boot U disk boot disk for hard disk repartitioning tutorial";

Finally, then reinstall the computer system, the system reinstallation can be solved by referring to the "U boot U disk boot for ASUS Win7 system use tutorial";

After the system is reinstalled, change the passwords used on the computer, including online banking, QQ, email, social networking, etc. Prevent individual users from being misappropriated for fraud, pyramid schemes, etc.

The above is the basic solution for the virus, users must be careful not to enter some unknown ** during the use of the computer, to prevent poisoning. Of course, after the computer is poisoned, we should solve it in time to ensure the security of the user's personal information.

If the laptop is poisoned, it must be particularly troublesome, you can try the antivirus software, if the antivirus software can't be removed, then you, you should take some special computer stores to take a look.

My book is also Acer's. Find the answer online, I hope it can help you.

When the computer is turned on, there will be a self-test process for the motherboard and the peripheral devices on the motherboard, and then it can enter the operating system. During the motherboard self-test process, there will be a specimen flashing in the upper left corner of the screen, under normal circumstances, it will flash once, if the motherboard or external equipment fails, there will be a phenomenon that the cursor in the upper left corner of the screen has been flashing after booting.

Here we divide the problem of cursor flickering after boot into several possible reasons for analysis:

1. The boot cursor flashes for a long time, but it can enter the system.

This phenomenon may be due to bad sectors on the computer's hard drive, but it is still barely usable. Therefore, if such a phenomenon occurs, you should quickly back up the important data stored on the hard disk to other computers, so as not to cause trouble when the hard disk is completely broken. Of course, if your drive is still under warranty, you can return it to the factory for repair.

Second, it can be self-tested when it is turned on, and it has been stuck in the screen of the cursor flashing after the self-test.

This fault is also the possibility of hard disk damage, but it does not rule out the possibility of damage to other peripheral devices on the motherboard. It is recommended to do a full scan of the hard drive, preferably using a general hard drive scanning tool such as MHDD. Once it is determined that the hard disk has bad sectors, etc., the hard disk should be repaired or replaced with a new hard disk immediately.

3. The computer can not be self-tested when it is turned on, and a black screen appears directly after the motherboard brand logo appears, and the cursor keeps flashing in the upper left corner of the screen.

This fault is very troublesome, and it is mostly caused by the aging of the motherboard. We can use the minimum system method to unplug all the interface cables on the motherboard except for the power cable, and then use a screwdriver or key to short-circuit the boot jumper on the motherboard. If the self-test can be normal, then we can use the elimination method to add the same boot detection to the other devices on the motherboard at a time until the failure occurs.

The last device added is the faulty device, and of course, the interface connected to the device on the motherboard cannot be ruled out. If the minimum system method also fails to self-test and the cursor flashes, then the motherboard can only be repaired or replaced with a new motherboard.

360 software only checks and does not kill, and it can't be killed, you can only redo a new system, either use the software that costs money, or use Kingsoft NetShield to try it.

If you can't get it right, go directly to the after-sales service.
